Fig. 4-28 G86 Machining Process
Process Description:
1. The cutter moves to the hole position (X, Y) in G00;
2. Moves down to the specified point R in G00;
3. Moves down to point Z at the bottom of the hole in G01;
4. Drill stops rotating;
5. Retracts to initial point (G98) or point R (G99) in G00;
6. Drill starts to rotate.
