Motion group. Machine and config dependent.
Example program
G0 G20 G90 G54 G18 G40 G49 G80 (SAFE START, XZ PLANE)
G0 X0.3 Y0 Z0.1 (CLEAR POSITION)
G97 S1000 M3 (1000 RPM)
G0 X0.22 (START DIAMETER)
…
G0 X0.3 Y0 Z0.1 (CLEAR POSITION)
G97 S1000 M3 (1000 RPM)
G0 X0.22 (START DIAMETER)
…
The full 7-line example is in the app. Example is in inch. Check offsets and clearances first.
Watch out for
- Overrides are fixed at 100 percent and feed hold waits until the move ends.
- Start and end with extra length so the axis is up to speed in the thread.
- Use G97 constant RPM, not G96, when threading.
