How it works
Modal, group 05.
Example program
G95 (FEED PER REV)
G01 Z-.5 F.004 (.004 IPR)
G94 (BACK TO IPM)
G01 Z-.5 F.004 (.004 IPR)
G94 (BACK TO IPM)
Example is in inch. Check offsets and clearances first.
Watch out for
- F30. from a G94 program becomes 30 inches per revolution in G95. Always reset F after switching.
- In G95 the tap feed is the pitch itself, F.05 for 20 TPI.
