Week 12: CAD/CAM Approach to part programming

Basically,
1. Part geometry is entered in 2D or 3D.
2. Tool geometry and machine tool type are entered.
3. Speeds and feeds are entered or calculated based on tool
and work material.
4. Inside/outside of geometry, and initial stock sizes are
selected.
5. Cutter paths are generated.
6. Cutter paths are converted to a machine specific language
(eg, G-codes).
These programs are usually built into better CAD systems or are
available as stand alone software
Some machine tools have these programmers built into the
controller.
