Manufacturing
Computer Aided Manufacturing
CAD – Computer Aided Design:
conceptual designs for new products
bill of materials
Computer Aided Manufacturing
CAD – Computer Aided Design:
Advantage:
no requirement for physical prototypes
Disadvantage:
CAD software data needs to be manually
converted into manufacturing instructions
Computer Aided Manufacturing
CAM: Computer-Aided Manufacturing
bridges the gap between the conceptual
design and the manufacturing of the
finished product.
Computer Aided Manufacturing
How?
CAM software directly converts CAD
software data into a set of manufacturing
instructions in the form of G-code
What is G-code?
Programming language for machine tools
Computer Aided Manufacturing
Why is G-code important?
G-code instructs machine tools to
manufacture a large number of items with
perfect precision.
Machine tools linked into “cells“ can
therefore perform single steps of a process.
