1. Positioning Control

2. 1. Point to Point Control (G0)
programming instructions that only identify the next position required. Usually for drilling, boring, reaming, tapping, etc.

3. Three movement systems
1. Axial path
2. 45 degree line path
3. Linear path

4. Operation steps 1. Position (usually at maximum feed rate) 2. Machine
3. Retract
cycle repeat

5. 2. Continuous Path Control (G1)
Also known as contouring
Synchronizes axis of motion to produce a path, usually a line or arc
Two or three distinct slide movements are involved, each slide movement being independent of the other and results in an angular path
Can cut contours in 2 axis (most in 3 axis) and some up to 6 at a prescribed feed rate

6. Continuous Path involves
Linear interpolation (G1) and Circular interpolation (G2 & G3)
