Learning Aim
To be able to differentiate between
machine beds.
Success Criteria
All 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.
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).
