PREFACE

This module series was created to introduce new product designers or students in the

Engineering Design subject offered in several program at the Terengganu Advanced

Technical Institute. Basically the participant will learn the basic usage of the software on

how to create or design simple part. Then the module will continue onto more difficult

design task.

The exercises were added specifically on Basic Block Design parts. They are meant to be

user initial approach on how to understand the basic knowledge of the software.

The module does not emphasize all Pro Engineer commands but instead make use relevant

capabilities that the software has, to create a design concept. Pro Engineer is a tool in this

module. Any relevant features that the software has and can be utilize during the design

concept will be dealt in the text.

Starting with several simple block design, individuals’ product to create and then following

is a complete Bell Roller assembly. The series of lessons indicates numbering systems,

which identifies the sequences needed to follow in order to complete certain task.

Sometimes notes outside the sequence also important to read through. As the user progress

with the module, notice that some sequences are left out and assuming that the user already

understand the demands to proceed without showing how to start.

It is imperative to realize that this is not the best way of designing given products.

Designing concept is very universal and there can be lots of means and ways of creating

certain product such as the one provided in this module. It is mainly to provide an open

window for the designer or students to be able to strive themselves into design field, which

is very interesting and also demanding especially in 3D world.

This module can be made as a self-learner completely. But by having an instructor to assist

would be the best way of learning courses such as this. Included in this module is a

complete files of all part designed as a reference assuming that the participant may got lost

in the middle of the design phase. But it is advisable not to look onto the files unless are

told to do so.

ACKNOWLEDGEMENTS

The inspiration for this module comes from the PTC Global Services modules, which has

brought me up to this level. Since PTC concentrates more on the software features, why not

create a module that can utilize the software into engineering course such as product

design.

I would like to thank Mr C.H. Lim and Mr. Ratnarajah, my former bosses in Grundig

Research and Development during my years of being a Product Design Engineer who has

taught me ample of knowledge in design field especially in plastic product.

Acknowledgment is also due to other companies that I’ve work with such as Mattel Tools,

MEC, and also Likom Research and Development. These four companies have provided

me great knowledge about design approach with different product background.

As always, special thanks are due to my wife, Norelizai Ilias, for tolerating my late nights

and weekends spent on this project, and to our children Aina, Sofiah, Fahim, and Adam for

their patience. Thank you for accepting my absent-minded and pre – occupied father.

To users of this module, I sincerely hope you enjoy the journey towards designing field.

Thank you.

INTRODUCTION

PRO ENGINEER WILDFIRE

WHAT IS PRO ENGINEER?

A suite of programs that are used in the design, analysis, and manufacturing of a

virtually unlimited range of products.

It is a parametric, feature – based, solid modeling system.

Feature – based:

Create parts and assemblies by defining features like extrusions,

sweeps, cuts, holes, slots, rounds, and so on.

Features are specified by setting values and attributes of elements

such as reference planes or surfaces, direction of creation, pattern

parameters, shape, dimensions, and others.

Parametric:

The physical shape of the part or assembly is driven by the values

assigned to the attributes of its features.

Any changes will automatically propagate through the model.

Can also relate the attributes of one feature to another.

Solid Modeling:

The computer model created is able to contain all the information

that a real solid object would have.

It has a volume and therefore, if a density is provided, the mass and

inertia can be found.

An important aspect of feature – based modeling in Pro E is the concept of

parent/child relationships.

A change to the parent feature will potentially affect the child.


vi Introduction

HOW TO START?

Below is the default start – up when entering into the program.

Default Start – Up Screen.

Navigator.

Shows the folder structure on the machine, with the current work

directory highlighted. The working directory is where Pro/E will

look for and save your files.

Allows the user to organize folders and web sites into group of

favorites accessed using the four tabs at the top.

Browser.

Allows the user to launch regular web pages and, for example,

download part files from the web directly into Pro/E.

The browser functions in the same way as normal web browsers.

Sashes.

Open and close Navigator and Browser screens.


Introduction vii

The Pro Engineer Screen.

Main graphic area where most of the action will take place.

The prompt/message window below the graphic area shows brief system messages

(including errors and warnings) during command execution. It is also where text or

numerical input is sometimes typed in response to command prompts that ask for

information (such as feature names or dimensions).

Pull-Down Menus is basically similar function to familiar Windows commands.

Short-cut Buttons provides immediate excess onto various commands compared to

pull-down menus.


viii Introduction

The right side of the graphics window is also the short-cut buttons that deals most

with the developing of the solid modeling.

The top toolbar (default).

Filter Setting helps identify only required selection during the development

process of the model.

MOUSE FUNCTION.

Wildfire is meant to be used with a 3 – button mouse with a middle scroll wheel all

the better.

“select”, “click”, “pick” a command or entity, this is done with the left mouse

button (LMB) unless otherwise directed.

The functions controlling the view of the object in the graphics window are all

associated with the middle mouse button (MMB) and scroll wheel. These are the

important Spin, Pan, Zoom functions.


Introduction ix

Some of these are used in combination with the Shift and Control keys on the

keyboard.

All dynamic view operations involve dragging the mouse. The dynamic view controls are

to display the 3D objects. When viewing 2D objects, some of the mouse functions change

slightly.

Right mouse button (RMB) is normally to open pop – up menu for further

selections of command.

Common Pro/E mouse functions 3D.

Note:

More commands and feature of Pro Engineer Wildfire will be dealt in detail when going

into the module completely. Off course not all features all used in this module. Once you

get to know the fundamental of the software, you should be able to explore yourself more

on the software capabilities with additional references from PTC or any other sources

available.

GOOD LUCK.


x Introduction

BASIC BLOCK DESIGN


Corner Bracket - 1 -

CORNER BRACKET

First off all you need to set your working directory so that all your design work will be

properly saved into appropriate location. Once having done that you may follow the

sequence provided for you below.

1. Create a new file name CORNER_BRACKET. Click onto an icon and you will

notice that a NEW dialog box opened as shown below.

Figure 1-1: “NEW” dialog box.


- 2 - Corner Bracket

2. After completing the above task, click OK to continue and change the unit into mm

by selecting the shown template below. Then click OK again to proceed further.

Figure 1-2: Change unit dialog box.

3. Make sure that all default datum icons are off except the datum plane icon. Below

are the relevant icons to be adapted.

Figure 1-3: Datum icons.

You will notice that on the screen, there are only three datum planes provided for you and

this is the common initial steps that you will always encounter during the design process.

First is to create a solid block using the top plane as the sketching area.

4. Select the Top plane> > placement > define > Sketch to go onto the sketching

mode.

5. Next is to click icon and start your sketching by clicking onto point 1 > point 2

> point 3 > point 4 > point 5 > point 6 and back to > point 1.

6. Drag your mouse away from point 1 and middle click to detach the line

construction. Middle click again to see the weak dimensions.

Your sketch should follow as shown in figure 1-4.



Figure 1-4: Sketched lines.

Notice that if your sketch is almost similar to the above, the provided dimension should be

as close as shown given below. When creating the lines, make sure that they are in exact

vertical and horizontal position except the last line when to detach it from the loop. Also do

not let the design intent activate the L1 symbol which indicates that you intended to create a

same length of lines. Otherwise your dimensions will be different than the one as shown in

figure 1-5.

Figure 1-5: Default dimensions sketched lines.

Do not worry about the value of the dimensions and its positions. Next we will reallocate

the dimensions and update the value according to the given specification of the corner



bracket. Assuming that your dimension position is as shown in figure 1-5 and you need to

change the dimension 69.49 to a different position.

7. Click icon and select the vertical line as shown in figure 1-5. Middle click

somewhere at the right side of the line to position the new dimension. Then click Ok

to accept the chosen sequence.

Notice that the dimension changes and positioned onto the desired location. You can do the

same sequence if the other dimension is not to your expectation.

8. Click the other dimensions by pressing it and drag them to a better location and

then released.

By having done the above, your sketch with the appropriate dimensions is as shown in

figure 1-6.

Figure 1-6: Adjusted position of dimensions.

Now you need to update the dimensions as per given by the bracket specification. To do

this, you need to select all dimensions before you change them. This is to avoid ambiguous

of values that might contradict to the sketches done earlier.

9. Middle click to active icon . Click from top left and drag until bottom right to

select all dimension and click icon to open the modify dimensions window.

Notice that all dimensions are highlighted to confirm that they are selected during the

grouping procedure.

10. Uncheck Regenerate before changing the value of the dimensions.



This is to make sure all dimensions are updated first before regeneration took place. The

dialog box is as shown in figure 1-7.

Figure 1-7: Updated dimensions.

11. Click to complete the sequence. Then click icon to go back to 3D. In the

dashboard area change the default depth value to 50mm and click to

complete.

The dashboard is shown in figure 1-8. You can also change the depth value by double

clicking the active value on the model.

Figure 1-8: Dashboard view.

By selecting an icon and choose the default orientation, your solid should look as

shown below in figure 1-9.

Figure 1-9: Solid created.



You may rotate your solid by pressing middle mouse button and drag it to any position you

desire. Next is to cut the first top portion of the block according to the given dimensions.

Make sure that the solid is at default orientation position.

12. Select insert > Extrude > placement > define and select the top surface of the

solid,> Sketch to go onto the sketching plane.

You need to add additional references before you do the sketching. This is to make sure the

line snap onto the created references.

13. Select Sketch > References and click onto the two edges shown in figure 1-10. Then

click Close.

Figure 1-10: Additional references.

14. Click icon and draw a rectangle from top left to bottom right as shown in

figure 1-11. Middle click to see the weak dimensions.

Figure 1-11: Shaded rectangle created.

Make sure that the rectangle snaps onto each sides of the block except the left vertical line.

That is why a horizontal dimension is given.



15. Change the dimension 54.93mm to 50 mm. Press middle buttons and then double

click onto the dimension and change the value. Press <enter> to proceed. Click

to continue with the next step. Click icon > Default Orientation.

At this point you will notice that the solid is added instead of removed. So you need to

change it from the dashboard area.

16. From the dashboard area, click onto icon and change the depth value to

30mm.

Figure 1-12: Remove icon on dashboard.

17. Change the direction of the cut if the arrow is showing away from the solid block.

You can click on the relevant arrow to do it. Finally click icon on the

dashboard to complete.

By selecting a default orientation, your solid should look as shown below in figure 1-13.

Figure 1-13: Solid model created.

The last process to complete the design is to cut the second small area. The same procedure

can be followed as before.

18. Select insert > Extrude > placement > define and select the top surface of the solid

as shown on figure 1-13, >Sketch. Select Sketch > References and pick two

additional edges for references as shown on figure 1-13. Click Ok > Close.



19. Click icon to change from solid to no hidden lines for easy sketching process.


figure 1-14. Press middle button and then double click on the dimension. Update

the dimension to 10mm > <enter>.


Again make sure it snaps to the reference edges. If there is more than one dimension then,

your rectangle does not snap to the created references.

21. Click icon to continue with the next step. Click icon > Default

Orientation. From the dashboard area, click onto icon and change the depth

value to 20mm > <enter>.

Figure 1-15: Arrow showing the correct direction.



22. Change the direction of the cut if the arrow is showing away from the yellow frame

block. You can click on the relevant arrow to do it. Then click icon on the

dashboard to complete. Click icon to change back to solid shading.

Finally your complete Corner Bracket should look like this:

Figure 1-16: Final Corner Bracket.

Save your final work. Click icon > <enter>.

Now you should have the basic understanding on how to create a solid protrusion and also

removing the solid area. Continue with the next solid creation to gain more experience in

designing simple solid block.

Good luck.



Notes:


Corner Block - 11 -

CORNER BLOCK

Again the initial stage is to set your working directory by presetting a folder before entering

into Wildfire program. Then the sequence to create this block is as follows:

1. Create a new file name CORNER_BLOCK. Click onto icon and you will notice

that a NEW dialog box opened.

Figure 2-1: “NEW” dialog box.


- 12 - Corner Block

2. Make sure to uncheck Use default template before clicking OK to continue. Next is

to change the unit into mm. then click OK to proceed for the next step.

Note that the sequence is the same as per the previous creation of solid block. We are

assuming that you are already familiar with the steps. Otherwise, please refer back to the

earlier section to recap.

3. Make sure that all default datum icons are off except the datum plane icon. Below

are the relevant icons to be adapted.

Figure 2-2: Datum icons.

Again this is to ease your design criteria only. If you feel comfortable with all datum icons

are active, then you may continue doing so. Sometimes too many datum icons may

complicate design creation. For this block, first we create a solid rectangle using top plane

as the sketching plane.


mode.

5. Next is to click icon and start your sketching by clicking onto the intersecting

point of the datum.

6. Pull down your mouse to the right and you will notice a rectangle has been created

as you move the mouse. Left click to detach the construction. Middle click to go to

a default icon .

Figure 2-3: Sketched rectangle.

Notice that we did not use the line construction but instead we use the rectangle icon. This

is another way of constructing simple rectangle block. Also there are only two dimensions

given because we snap the starting point on the intersecting of datum planes.


Corner Block - 13 -

Next is to update the two dimensions according to the given specifications of the corner

block.

7. Double click onto each dimension and change the horizontal value to 100mm and

the vertical value to 60mm. Press <enter> for each updated value.

8. Then click icon to go back to 3D. In the dashboard area change the default

depth value to 40mm > <enter> and click to complete.



Now is to cut the big area from the top of the block. Make sure additional edges of the

block is selected during the reference identification. From here it is good to inactive the

datum planes and change from shading to no hidden view.


solid, >Sketch. Select Sketch > References and click onto the vertical right edge

and bottom edge line of the solid block. Next click Ok > Close.

10. Sketch a rectangle shape as shown in figure 2-5. by selecting icon . Update the

dimensions shown in the figure.



- 14 - Corner Block

11. Click to continue with the next step. From the dashboard area, click onto icon

and change the depth value to 30mm.Click icon > Default Orientation to

see the 3D profile. Also click icon if the direction is away from the solid.

Figure 2-6: Remove block area.

From figure 2-6, you notice that the remove block is in the original solid and there are two

yellow arrows showing that this is a cut procedure and not protrusion. Also here you can

use the icon to flip the cutting position instead of clicking onto the yellow arrow.

12. Finally click icon on the dashboard to complete.

By selecting a default orientation with shading, your solid should look as shown below in

figure 2-7.


Next is to cut the right top portion as given in the specification. The same procedure can be

followed as before. Make sure all necessary references are identified before going to the

sketching mode.


Corner Block - 15 -

additional edges for references as shown on figure 2-7. Click Ok > Close.



figure 2-8. Update the dimension to 30mm.


16. Click icon to continue with the next step. From the dashboard area, click onto

icon and change the depth value to 10mm.


You can click on the relevant arrow to do it. Then click icon on the dashboard

to complete.


Figure 2-9: Solid shown in no hidden view.

The last process to complete the design is to cut the bottom left side of the block.


- 16 - Corner Block


as shown on figure 2-7, >Sketch. Select the relevant edges as a reference. Then

click Ok > Close. (Or double click twice to close the references).

19. Click icon and draw a rectangle from top left to bottom right on the desired

area. Update the dimension to 20mm.

20. Click icon to continue with the next step. From the dashboard area, click onto

icon and change the depth value to 20mm.


Then click icon on the dashboard to complete.

Finally your complete Corner Block should look like this:

Figure 2-10: Final Corner Block.

Save your final work. Click icon > <enter>.

Hopefully up to this point, you should have confidence in using the protrusion and cut

process. Also using default and created references helps to ease your sketching process.

Keep it up.

Notes:


Guide Block - 17 -

GUIDE BLOCK

This guide block needs additional process to complete. You need to use cut by sketching on

side walls and use different features than giving depth value. The rest of the feature

creation is basically the same as the first two blocks that you’ve encountered.

The first steps to design this block is to create a solid piece looking from the top view with

a depth of 60mm.

As a reminder, set your working directory properly before starting your design creation.

The sequence is as follows:

1. Create a new filename GUIDE_BLOCK. Uncheck the use default template to

change the unit into mm.

2. Make sure that all default datum icons are off except the datum plane icon.

point of the datum. Pull down your mouse to the right and you will notice a

rectangle has been created as you move the mouse. Left click to detach the

construction. See figure 3-1.



- 18 - Guide Block

5. Click on icon to create a slanting line and a small rectangular within the big

rectangle shape created earlier. See figure 3-2.

Figure 3-2: Additional lines sketched.

6. Next is to remove unwanted lines by clicking icon . Click at one position and

drag it across the unwanted lines and release the button. See figure 3-3.

Figure 3-3: Removed lines.

7. Do the same process to remove the right vertical line of the smaller rectangle. The

final sketch with rearrange and updated dimensions should look as shown in figure

3-4.

Figure 3-4: Final sketch complete.


Guide Block - 19 -

Now is to update all the dimensions according to the given specification from the Guide

Block.

8. Select all dimensions and click icon to update them. Make sure to uncheck the

regenerate command before updating. The value are given in the modify dimensions

dialog box shown in figure 3-5.

Figure 3-5: Dialog box.

9. Then click icon to complete the sequence. Click icon to go back to 3D. In

the dashboard area change the default depth value to 60mm and click to

complete.




- 20 - Guide Block

The next step would be to cut the big portion of the block which is on the right side. Use

the top surface of the block as the sketching plane. Always starts your next feature creation

with the block at its default orientation to avoid orientation confusion.


solid, >Sketch. Select Sketch > References and click onto the vertical right edge,

bottom horizontal edge, and slanted edge line of the solid block.

11. Next click Ok > Close. Sketch a rectangle shape as shown in figure 3-7.



and change the depth value to 40mm. Also click icon if the direction is

away from the solid.

Figure 3-8: Removed block area.


Note that there is no dimension constraint during the cutting process. This is because the

references selected are enough to justify the created rectangle. Also you notice that creating

a cutting block does not have to be the same shape as the block area to be removed.


Guide Block - 21 -



The next process is to cut the V shape using the front wall as the sketching plane.

14. Select insert > Extrude > placement > define and select the front wall of the solid

as shown on figure 3-9, >Sketch. Select Sketch > References and pick all

additional edges for references from the front wall except the bottom edge. Click

Ok > Close.


16. Open icon line to select the centerline, as shown in figure 3-10.

Figure 3-10: Choices of lines.

17. Draw a centerline going through the center of the front wall. Left click on top edge

line somewhere in the middle. Move the cursor down and left click again once the

line created is vertical. See figure 3-11.

Figure 3-11: Centerline creation.

18. Click icon to create a V shape as shown in figure 3-12.


- 22 - Guide Block

Figure 3-12: V shape lines.

From figure 3-12, notice that you need to change the position of the dimensions according

to the specification given for the Guide Block.

19. Click icon and select right vertical edge with point 1 and middle click

somewhere on top. Do the same sequence with the left vertical edge and point 2.

20. Next click both V shape lines to active the angle created. Your final dimension

should look as shown in figure 3-13.

21. If there is an extra dimension appear, click icon and pick point 1, point 2, and

centerline to make them equal divided.

Note that you can find the constraint icon by expanding the default icon as shown below in

figure 3-13.

Figure 3-13: Expanded constraints icon.

Figure 3-14: Updated dimensions.


Guide Block - 23 -

22. Update the dimensions as shown in figure 3-14 and click icon to go to the 3D

view.

Use your mouse to rotate the solid and from the dashboard, you need to change the

command of extrusion path to thru all instead of given depth. Also don’t forget about the

remove material icon.

23. Change the command from the dashboard as shown in figure 3-15.

Figure 3-15: Dashboard command.

24. Also change the direction of the cut if the arrow is showing away from the solid

block. Then click icon on the dashboard to complete.

Change your solid view to default orientation and your solid should look like this:

Figure 3-16: Solid block.

Finally is to add another V cut across the bigger V cut as shown in the specification. Same

procedure can be done here. The only different is the sketching plane will be on either side

of the side wall of the solid. Here we will choose the left side wall as the sketching plane.

Rotate the solid so that the left side wall is facing you.

25. Select insert > Extrude > placement > define and select the left side wall of the

solid, >Sketch. Select Sketch > References and pick all additional edges for

references from the left side wall except the bottom edge. Click Ok > Close.


- 24 - Guide Block

26. Draw a centerline going through the right side of the left side wall. Click icon

to create a V shape. Then update the required dimensions as shown in figure 3-17.

Figure 3-17: Update dimensions.

27. Click icon to go to the 3D view. Change the command from the dashboard as

shown in figure 3-15.

28. Also change the direction of the cut if the arrow is showing away from the solid

block. Then click icon on the dashboard to complete.

Note that the dimension for the centerline may be omitted if you add constraint of equal

divided for the triangle created.

Finally you’ve created the Guide Block and it should look like this:

Figure 3-18: Final solid block.

Save your final work.

Notes:


Base - 25 -

BASE

Base design block looks difficult to create for some users. But in fact it is not that difficult

if we study it thoroughly. Basically, what we need to do first is to create a solid block

shaped look like from x-direction with a depth only half the total value of 190mm. The rest

is adding and removing materials and with a bit of chamfering procedure which is the new

feature given here. Finally we can copy mirror the solid to create the other half of the

complete Base design.

Locking Base - 31 -

LOCKING BASE

Even though this Locking Base solid looks easy to design, you may find it intriguing at

certain aspect that some means of thinking needs to be done before actually going into it.

The area A and B are not as easy as it looks. There are various ways of tackling this

problem and one of the ways is to use the sweep cut with a pre sketch trajectory. So for this

design you will learn how to make use of sweep feature. The rest of the design is again

basic and should be an additional practice for you.

PILLOW BLOCK

The reason why we are to design this block is to make use of the feature rounds. It can be

as your first steps of using such features. Unless you’ve already master most of the features

from Wildfire, then you may omit this portion of the design stage. Anyway it would still be

a good exercise to improve your basic knowledge in design field.



1. Create a new filename PILLOW_BLOCK. Uncheck the use default template to



To start, you may need to create a rectangular block first before adding up all the necessary

rounds and holes. From the specification given above, you can calculate the sufficient size

for the block. Treat it as a raw material size before going into machining process.

intersecting point of the datum. Pull towards opposite direction and you will notice

a rectangle has been created as you move the mouse.

5. Make sure that they are equally divided. Left click to detach the construction.

Again, to justify that you have created an equally divided rectangle is by having only two

dimensions. Also notice the arrows on each end point.

6. Update the dimensions as shown in figure 7-1.

Your present solid should look like this:


Next is to create a full round on top of the block. You can either click onto the top edges by

pressing control button when selecting the other edge. Then right click to select round

edges. Or follow the next sequence.

8. Click Insert > Round and select the top two long edges from the solid. Press

control button to select the other edge together.

9. Next click Sets from the dashboard and select full round. Then click icon to

complete the sequence.

The tricky part of this feature is when selecting the edges. Sometimes you might select the

wrong edges. All you have to do is undo the steps and reselect the correct edge.

Guide Bracket - 49 -

GUIDE BRACKET

The best way to design a solid block like this is to look at the most common shape. You

should see that the least feature creation for this is by using the y-direction as the first

sketching plane. Probably you need to be skillful enough to sketch certain shapes during

the 2D sketching mode. Using a line icon would be ideal for this shape. It will be a good

exercise for you.

Again as a reminder, set your working directory properly before starting your design

creation. The sequence is as follows:

1. Create a new filename GUIDE_BRACKET. Uncheck the use default template to

Flanged Coupling - 91 -

FLANGED COUPLING

Here is another good exercise for you to do. It is a good practice to understand the types of

drawing information given and be able to extract necessary dimensions into the creation of

the solid part of the unit. Designing this flanged coupling makes use of the pattern features

and revolves protrusion. You will also need to sketch a diamond shape and add on to the

revolved solid creation. Final touch up would be rounds and a chamfer features.

Assembly Fundamental - 123 -


Assembly process can be easily assembled when all relevant references provided are in line

and fits to all necessary requirements given when designing each part separately. It is truly

important that the given specifications are vividly correct before pursuing the design

process. Otherwise the assembly of the components will be incorrect and will leads to time

wastage and efforts.

Assembly can be done after all relevant components are developed first, then each

components will be assembled one by one to compose as an assembly product.

Alternatively, components of an assembly product can be designed and developed in

assembly mode whereby all relevant references are determined during the development of

the product itself. This method is mainly for a much tougher product assembly. When

dealing with a simple assembly product such as the Bell Roller Assembly parts, such

components can be designed and developed separately and assembled at the end of the

design process.

Here, we will start with designing each component of the Bell Roller product. Then we will

assemble them together to produce the assembly required. To do this, we need to confirm

the references needed before designing them, for instance, the Roller part must be design

with the axis of revolution exactly symmetrical to the part itself. Also the Shaft part needs


- 124 - Assembly Fundamental

to be developed with a plane divided equally so that those references can be used as part of

the assembly utilities. Otherwise, you may encounter some difficulties during assembly

procedure without having appropriate references. New reference may need to be added just

to fulfill the basic requirement of assembly procedure which is definitely a waste of time

and effort.

Designing product needs a lot of patience and stringent focus onto the issue of the part or

parts to be developed. Composition of components into developing a new product needs a

head on thinking of how or what would be the best way of combining such designed

methods so that the complete assembly of the product would be the best solution achieved.

Probably by having rough sketches on various selections of methods for assembly would

definitely help to justify the best possible solution for any designed product especially

assembled parts.

As a starting point for intervening into assembly process, this Bell Roller product design

will help the user to understand the basic needs when dealing with product that needs to be

assembled either during development process or even after all of the design components

are complete. It is best that you follow all the sequences given and not to miss out any

notes provided in between the sequences.

Good luck…


Cast Iron Bracket - 125 -

CAST IRON BRACKET

First thing that we can see with this part is that it is symmetrical. So when starting to design

solid model, make sure that a datum plane is situated in the middle of the part. This datum

plane will help us align the component easily when doing assembly process. It should be

quite easy to develop solid model for this part.

Set your view to Default Orientation, and your solid will look as shown in figure 20-2.


Next we will add a vertical wall which is 5mm offset from the Front plane. So we need to

create a new datum to make use of it as a new sketching plane.

6. Click icon and select Front datum plane to offset 5mm inside towards the

solid. Key in 5mm in the translation box from the Datum plane dialog box as shown

As you should know that we can actually do the holes by using the hole features itself. But

sometimes using the cut features may be more convenient here because you can make use

of the round edges of the plate created earlier as the main references for this hole creation.

Next is to create a right angle triangle rib at the middle of the bracket. Here we can do the

sketches using the Right Datum plane and protrude the solid evenly. So you need to

Revolve feature is the best method to produce this part. We may need to look at the

assembly method that we are going to apply when assembling this part onto the other

component of the Bell Roller. Since the shaft should be in the middle of the complete

assembly product, it is best to have a datum plane situated equally divided between the

Bell Roller Assembly - 147 -

BELL ROLLER ASSEMBLY

First is that we need to know what are the parts to be assembled together and the parts must

be in the same folder with the assembly file. Also we need to be very careful with units’

correlation here. Different unit types can cause big problems into assembling any product.

Setting a proper unit when doing designing is very important and also the references of

each component plays major roles into developing an assembly product.

There are many ways to assemble this Bell Roller product. Which is the best way is the

question to be answered. First, we need to know which component of the assembly is the

fixed item. When assembled, no movement occurs on this component. This part would be

the best component to be as a default assembled part in the assembly. Here, we will

assemble the Cast Iron Base part first because it is a fixed component.

Please make sure that your working directory is correct.

1. Click icon and change the type from Part to Assembly and change the name

asm0001 to Bell_Roller. See figure 25-1 below.

3. Then click OK to complete the sequence.

At this point, we have created an assembly file but no parts or components available inside.

So we need to assemble or bring them into this file. Proceed to the next sequence.

4. Click icon and choose Cast_Iron_Base.prt part file from the Open dialog box.

Click Open to continue.

5. From the dashboard expand the Automatic Assembly and click Default as shown in

Now you have added first component into the file and the position at default orientation is

as shown below in figure 25-4.

Figure 25-4: Cast Iron Base Plate added.



Note that if the position of your base is not the same as shown above, do not be worried.

This is because that when designing your base, you may have chosen different plane as

your sketching or possibly your second reference during selecting the sketching plane

might have oriented differently. For assembly purposes this should not be an issue as long

as you know which reference to choose to assemble the component.

Additionally, you also will notice that the Model Tree section has change with the base

assembled.

Figure 25-5: Model Tree for the assembly file.

Next is to add another component and this time is the Cast Iron Bracket part. We know that

this bracket has two holes with the same position and size with the Iron Base. We will use

these holes as our reference to assemble them together.

box. Click Open to continue and click to active the axis for assembly purpose.

Figure 25-6: Assembly References.



8. Select surface Side A > Side B (bottom surface of the bracket) as the first

reference.

Figure 25-7: First Reference selected.

Notice that the bracket is shifted upwards to level with the side A of the base and side B of

the bracket surfaces.

9. Next select the first axis combination which is axis A4 (see figure 25-6).

Figure 25-8: Second Reference selected.

Even though the status mentioned Fully Constrained, this component still can rotate about

the Axis A4 combination. So we need to add one more constrain to prevent this from

happening.



Figure 25-9: Assembly dashboard.

10. Click Placement > New Constraint > select the second axis combination which is

axis A3 (see figure 25-6).

11. Finally select to complete the task.

You updated assembly product should look like this:

Figure 25-10: Updated assembled product.

According to the assembly process for this product, two brackets are needed for this

assembly. We need to add the same bracket onto the other side of the base using the other

two axes A1 and A2 as part of the references.

Note that your assembly axes numbering might be different that from this module, but the

sequences of assembly should be similar.

12. Click icon > select Cast_Iron_Bracket.prt > Open.



Figure 25-11: Assembly References.

13. Select surface Side C > Side D (bottom surface of the bracket) as the first

reference.

14. Next select the first axis combination which is axis A1 and A3 (see figure 25-11).

Figure 25-12: Updated assembly process.



Notice that the new bracket is shifted to align with A1 and A3 together but facing

backwards. So we need additional reference to rotate the bracket and that is by adding

another axes combination of A2 and A4. (See figure 25-12)

15. Click Placement > New Constraint > select the second axis combination which is

axis A2 and A4 (see figure 25-11).


By adjusting the position of the present assembly product, your solid should look like this:

Figure 25-13: Updated assembled product.

17. Save your work. Click icon > <enter>.

It is a good practice to save your work even though it is yet to be completed. This is to

make sure that back up is there for you to retrieve if sudden issues occurred such as power

failure or your computer systems hang, and no recent data is available.

Next is to add or assemble the shaft. You can assemble different component such as the

roller if you know which reference to use. Here you will realize the benefit of pre-

arrangement of the datum plane in the component files.

18. Click icon > select Steel_Shaft.prt > Open.

19. Click to active the axis for assembly purpose unless it is already active during

the earlier session.



Figure 25-14: Axes reference.

20. Select the first axis combination which is axis A1 from the shaft and one of the

brackets (see figure 25-14).

At this point the shaft will move and aligned with the selected axes. You can actually move

the shaft by right clicking at the graphic area to pop-up a menu and select Move

Component.

21. Right-click at any graphic area > select Move Component > Left-click on the

shaft and move the cursor to adjust the position of the shaft to suit your needs (see

figure 25-15).

Figure 25-15: Pop-up menu.



When dealing with assembly files, you will need datum planes as references but not all are

required at a certain period of time. Also certain components which are already assembled

may not be relevant. So you need to hide it temporarily and you can do this when needed.

22. From the Model Tree, Right-click on the Cast-Iron-Base.prt > Hide to hide the

base part from the assembly.

23. Select icon > to deactivate datum axes and activate the datum planes.

Notice that the base part is not seen in the assembly. This will reduce the number of datum

planes activated and will ease the selection of datum planes needed for the next reference.

Continue with the next sequence.

Figure 25-16: Selected Datum Planes.

24. Click Placement > New Constraint > select Front Datum plane of the shaft and

ASM_Front Datum plane (see figure 25-16).

In the dashboard, make sure that the Align constrain is to make sure

that the shaft part is exactly in the middle of the assembly profile. Otherwise click

expansion mark and change it.

25. Finally select to complete the task. Click icon to close the datum planes.



Your updated assembly file is as shown below:

Figure 25-17: Updated Assembled product.

Remember that the Roller was designed with the datum planes created in the middle and

we know that this component is assembled in the middle of the shaft. So we do not have

any problems to hide both brackets in our assembly file as we did to the base earlier.

26. From the Model Tree, Press Ctrl Button > Pick on both Cast-Iron-Bracket.prt >

Right-click > Hide to hide the base part from the assembly.

27. Select > to activate the datum planes and axes.

28. Click icon > select Cast_Steel_Roller.prt > Open.

Figure 25-18: Selected Axes.



29. Next select the axis combination which is axis A1 from both the shaft and the roller

(see figure 25-18).

30. Right-click at any graphic area > select Move Component > Left-click on the

roller and move the cursor to adjust the position of the roller to suit your needs.

31. Click Placement > New Constraint > select Front Datum plane of the roller and

ASM_Front Datum plane.

32. Change the assembly constrain to > to complete the task.

Your updated assembly file is as shown below:

Figure 25-19: Updated Assembled product.

The last component to assemble is the bushing. This bushing is fixed to the center hole of

the roller and in between the shaft. So the main reference would be the axis of rotation for

both items and the mated surfaces between the bushing and the roller. The shaft can be

hidden too before the next assembly. Continue with the sequence.

33. From the Model Tree, Pick the Steel-Shaft.prt > Right-click > Hide to hide the

shaft part from the assembly.

34. Select to activate the datum axes unless it is already active.

35. Click icon > select Bronze_Bushing.prt > Open.

36. Select the axis combination which is axis A1 from both the bushing and the roller.

37. Next is to select surface A > surface B from the roller and the bushing respectively.

Figure 25-20: Selected surfaces.



38. From the dashboard, change icon to . This is to completely mate the two

surfaces.

39. Select to complete the task.

You can add another bushing with the same sequence but only on the other side of the

roller.

40. Click icon > select Bronze_Bushing.prt > Open.

41. Select the axis combination which is axis A1 from both the bushing and the roller.

42. Next is to select surface C > surface D from the roller and the bushing respectively.

Figure 25-21: Selected surfaces.

43. From the dashboard, change icon to . Change >

to complete the sequence.


After going thru this sequence, notice that every time we use axes as one of our assembly

reference, we only need minimum two references to complete the assembly requirement.

Also knowing the flexibility of hiding and unhide parts of the assembly will benefit the

user. Making use of the movement of parts during assembly sequence also helps the user to

rearrange the position for better and easier selection.

45. From the Model Tree, Press Ctrl Button > Pick all the hidden parts > Right-click

> Unhide to retrieve them back into the assembly view.

46. Save your work. Click icon > <enter>.



Your final assembly product should like this:
