Contour Toolpaths —Part 2 Lesson 3 Page 3—1

LESSON 3 ! CONTOUR TOOLPATHS ! PART 2

INTRODUCTON:

This lesson builds on the basic procedures you were introduced to in the first Contour lesson. You will gain ex!

perience in additional geometry selection (Chaining) techniques that will allow you to cut most Contour shapes

you come across. The toolpaths will consist of several new types of contours.

Overview of Exercise:

In this lesson we will machine the part shown by first Facing the 5.0 X 8.0 stock, then machining the yellow

areas shown by using several different types of 2D contour toolpaths and tools.

NEW CONCEPTS COVERED IN THIS LESSON:

! Facing rough stock

! Multi!pass contour to cut an open pocket shape

! Removing excess stock

! Chamfer contour toolpath

! Multiple techniques for contour chain selection

! Chain Manager options

! Review of basic Mastercam for SolidWorks general workflow procedures





Contour Toolpaths ! Additional Reference Information:

REFERENCE INFORMATION: 2D GEOMETRY SELECTION OPTIONS Single Edge: Click the edge. (The Mastercam Chain Manager gives the option to automatically propogate along tangencies.) Multiple Edges: CTRL-Click each edge. (The Chain Manager will display all individual edges. The CHAINS tab will show how Mastercam has connected continuous edges into a single Chain.) Select Tangency: Right Click on Edge and choose the option from the menu. (This will select all of the edges tangent to the one highlighted and put them in the Selection list in the Chain Manager.)



Select Loop: Right Click on Edge and choose the option from the menu. (This will select every connecting edge on a face, whether tangent or not. If the wrong Loop is chosen by SolidWorks, click the yellow arrow to toggle to the other option.) Partial Loop: Click the first entity, then CTRL-RIGHT Click on the second entity to choose the option from the menu. NOTE: When CTRL-RIGHT Clicking on the second entity, you must select on the end of the entity nearest the direction you want to close. For more information, see the SolidWorks Help menu. (This will allow a faster method of selecting a large number of individual edges on complicated contours.)

Select Face: Click on a Face. (This will select every individual edge on a face, including interior edges, whether tangent or not. The Chain Manager gives the option to use only outer loop on faces. This is useful if you only want to cut the outer shape.)



In this task you will choose the view to machine from

and locate part on the machine. Due to the shape of

the model, there is no good location for the origin. We

will use SolidWorks to create the origin location first.

1. Open the part “CONTOUR 2.SLDPRT”

2. From the SolidWorks Drop!Down View Menu, make

sure View Sketches is selected.

(We will need to see Sketches in a later step.)

3. Select this face and select Insert Sketch from the

pop!up icons or from the SolidWorks Insert menu.

(This will start a new sketch on this top face. The

following steps will have us create a single point at

the theoretical sharp corner of the stock. So we can

locate the machining origin where we want it.)

Process Step 1: Prepare and Orient Model for

Machining

CONTOUR TOOLPATHS ! PART 2 ! TUTORIAL



4. Rotate the model similar to the view shown and

select both of the edges by pressing the Control key

and selecting these two edges.

5. Select the Point icon from the SolidWorks Sketch

toolbar or from the drop down menu Tools – Sketch

Entities – Point, to create a point entity at the

intersection of the two lines.

(Note: You must select the (2) edges first to get

the point at the intersection.)

6. Exit the Sketch.

(Right Mouse Click and Select Icon.)



7. From the Mastercam drop down menu, select

View Manager.

8. View Manager Dialog settings:

9. Select the Geometry button.

10. Rotate the model as needed so you can pick the top

Solid Face to be the Machine View.

11. Rotate XY as desired for Direction.

(We will leave at 0° in this example.)

12. Click OK to accept.

13. Give the new view a Name.

(“2D Machining View” in this example.)



14. Set the Current View and Origin equal to this new

view by clicking the “EQUALS” button.

15. Select button to choose the desired Origin Point.

16. Select the sketch point previously created

as shown.

(In order to see this sketch Point,

View Sketches must be on. See Step # 2)

17. Click OK to accept.

18. Click OK to Accept again to exit and save the View

Manager settings dialog.

(The Mastercam Origin should be located on the

point entity as shown.)



In this task you will supply Mastercam with information

about tool information and stock size prior to beginning

the machining operations.

19. Select the Mastercam Toolpath Manager Icon from

the Property Manager page.

20. Expand the Properties in the Toolpath Manager.

(Click the plus (+) sign if the Files, Tool Settings

and Stock Setup icons are not visible.)

21. Select the Tool Settings icon

22. Change or confirm the highlighted parameters as

shown:

Process Step 2: Create the Job Setup

REFERENCE INFORMATION For further information on other settings, see the Mastercam Help file by clicking Program # Identifies the program in the output NC machine code. Feed Calculation from tool uses the feed rate, plunge rate, and spindle speed directly from the tool definition. Assign tool numbers sequentially assigns the next available tool number. This option overrides the tool numbers stored in the tool definition. Warn of duplicate tool numbers informs you when a duplicate tool number is entered and displays a description of the duplicate tool. Override defaults with modal values When selected, the default values for any of the checked items will be the value from the previous operation. These override the values found in the toolpath defaults file.



23. Select the Stock Setup tab.

24. Select the icon and then set the Stock View to the

previously created view. (“2D Machining View”)

25. Select the Bounding Box button.

26. Accept the default Bounding Box values as shown:

(In this example, the Stock size will be defined as

the extents of the solid model.)

27. Click OK to accept and close the Machine Group

Properties.



During this section you will select the portions of the

solid model that CNC tool will cut. We will generate 5

separate operations to machine the part in this process

step. These will include:

Facing the Top of the Stock

Open Contour Toolpath with Multiple Passes

Partial Contour Toolpaths

Contour the Entire Outside Periphery

Chamfer the top edge

Facing the Top of the Stock

28. Select Facing Toolpaths from the Mastercam

Drop Down Menu or Command Manager.

(Facing operations will machine the entire top

surface of the model to prepare for subsequent

operations.)

29. Rotate model as needed and select the top face as

shown:

(Note: In this example, the shape is simple enough

to allow selecting the top face. In other cases,

additional sketching may be required to define the

stock shape for the facing operation.)

30. Click OK to accept and close the Chain Manager.

(In facing operations, the entire boundary must be

closed and the facing tool cuts inside the boundary,

so chaining direction and cut side is not required to

be set in this example.)

136. Results:



With this step, we will view all operations in the

completed toolpath on the computer screen to confirm

that we have the results we expected before we send

the NC code to the machine. This step will help avoid

costly mistakes.

Backplot the toolpath.

(Backplotting is the quickest way to confirm the

toolpath. With backplot, you do not see material being

removed, you only see tool motion compared to the

finished part.)

137. Make sure ALL operations of the toolpath are

selected.

138. Select the Backplot button.

139. Play the toolpath.

(These buttons are similar to a video recorder.

You can hover your cursor over each button to

see what their function is.)

Process Step 4: Backplot and Solid Verify the

Entire Toolpath



140. Backplot results:

141. Solid Verify the toolpath:

142. Make sure ALL toolpaths are selected.

143. Select the Verify button.

REFERENCE INFORMATION Display with Color Codes Shows the toolpath moves using the color codes from the Backplot Options. Display Tool Toggles the tool on and off Display Holder Toggles the tool holder on and off. Display Rapid Moves Includes the rapid moves in the backplot. Display Endpoints Shows the entity endpoints in the toolpath. This allows you to see how many tool moves actually occur. Display Quick Verify Displays a shaded path the width of the tool as the backplot progresses. Options Opens the backplot options dialog.

Details Gives tool location and other information

during the backplot.



144. Select to display the Holder and Tool.

145. Play the toolpath.

146. Results from Verify:

(Completed Toolpath)



(Mastercam for SolidWorks allows you to make changes

to your geometry and any parameters or settings

without requiring you to start over.

In this example, an Engineering Change Order requires

the slot to change dimensions. We will make the

necessary modifications and make the required changes

to get a correct new toolpath.)

ENGINEERING CHANGE ORDER:

A. Slot dimension to change from 2” wide by 1.75”

deep to 2.5” wide by 2.5” deep.

147. Double Click on an interior face of the slot on the

solid model to display the parametric dimensions.

Process Step 5: Making Changes—Editing the Toolpath



148. Double click on the text of the first dimension

value to be changed.

149. Change the dimension to the new value.

(In this example the 2.00 dimension needs to

be changed to 2.50)

150. Click the Regenerate button to rebuild the

solid with the new value.

151. Click OK to accept the new value.

152. Change the 1.75 dimension to the new value

by repeating the procedure.

(In this example the 1.75 value needs also

needs to be changed to 2.50)

153. Results:

(Make sure your model matches the

screenshot shown.)



154. Regenerate the toolpath to see the updated

toolpath.

(Note: Since we did not change the overall

dimensions of the model size, we will not need

to update the Stock Setup on this example.)

Select All Operations in the Operations

Manager.

155. Regenerate all Selected Operations.

156. Solid Verify all operations.



157. Results of Verify:

(NOTE: The dimensional changes caused a

problem with removing all of the material from

the open contour area. We will need to make

a change to the parameters to fix this.)

158. Select the Parameters icon under Operation

#2 from the Operations Manager.

(Note: Operation #2 is the operation that cuts

the open pocket area. You can confirm this by

hovering your cursor over the operation and

reading the comment we previously input to

identify this operation.)



159. Set the Multi Passes parameters as shown:

Rough Number = 4

(All other parameters should remain as shown.)

160. Click OK to accept and close the parameter dialog.

161. Click the icon to Select all Dirty Operations.

(Since we changed parameters, Mastercam

recognizes the toolpath needs to be regenerated

and marks it as “Dirty” in the Operations

Manager.)

162. Select the icon to Regenerate all Dirty Operations.

163. Repeat Solid Verify procedures.

(Select all operations then Solid Verify all

Selected operations.)

164. New Modified Verify results:



We now will take the toolpath information we have

created and post process it to a language that the

machine tool can read.

165. Select the operations to Post Process.

(Usually we will select ALL Operations to post.)

166. Select to Post Selected Operations.

Process Step 6: Post Process the Program to

Generate NC Code



167. Set the Post Processing options as shown:

168. Click OK to accept and Post Process the toolpath.

169. Give the program a name.

(CONTOUR 2.NC is used in this example.)



170. Resulting NC Code:

171. Close the Mastercam X Editor Window.

172. SAVE your SolidWorks file.

SUMMARY:

In this lesson, you added to your experience in the basic procedures of cutting contour shapes with Mastercam

for SolidWorks. You experienced multiple new ways to select geometry to identify chains to cut and created a

program with multiple operations. After completing this lesson and the practice exercises that follow you

should be able to:

! Select multiple sets of individual edges to create Chains to generate Contour toolpaths.

! Select Tangent edges to create Chains.

! Select Loop edges to create Chains.

! Face extra stock from the top of a part.

! Create a cleanup contour pass around the outside of a part.

! Chamfer edges of a part.

! Cut an open pocket area with multiple contour passes.

! Remove areas that have additional stock with multiple contour passes.

! Verify using Backplot and Solid Verify multiple operations.

! Modify parameters and solid model dimensions and have the toolpath update parametrically.

! Create NC code to send to the machine.
