Cutting, Shaping And Forming
Akopọ
Once a part is marked out it has to be brought to shape, and that means removing the material you do not want and forming what is left. Cutting, shaping and forming is the heart of practical workshop skill: choosing the right saw, file, drill, machine or CAM process for the material in front of you, and using it in a way that is accurate, efficient and safe. The same shape can often be reached several ways, and a designer who understands the processes makes the choice that gives the best result for the least effort.
This note works through cutting and material removal for woods, metals and polymers: the hand saws, files and chisels; the power and machine tools such as the pillar drill, scroll saw, lathe and sanding machines; the forming processes including line bending, vacuum forming and bending sheet metal; and the CAM routes of laser cutting and CNC routing. It explains how to match the process to the material and why each tool cuts the way it does.
