Learning AimTo be able to differentiate between machine beds.

Success CriteriaAll of you will be able to list the properties that allows a machine tool to perform well.

Most of you will be able to draw a deep cross section bed.

Some of you will be able to evaluate guide-ways and produce 3D CAD drawings.

Learning Aim

To be able to differentiate between machine beds

What factors affect a machine tool’s accuracy?

What differentiates the best from the cheapest machine tools?

Learning Aim

To be able to differentiate between machine beds

Produce a PowerPoint presentation that covers the following information:

Slide 1 : Four properties a machine bed/tool must have to maintain accuracy

Slide 2 : Explain what a deep box section bed type is. Why is it an advantage? Include a diagram you have produced in AutoCAD

(Extension : Produce a 3D CAD Extruded Model of this bed type)

Slide 3 : What is a guide-way? What are the 8 principle requirements of a guideway?

Slide 4 : What are the four types of slide-way? Produce an AutoCAD diagram and explain the uses for each.

(Extension : Produce a 3D CAD Extruded Model of these slide-ways).
