G94 Feed per minute mode / End facing cycle
Haas NGC G-code · Mill, Lathe
On mills: Feed per minute mode
F is in inches per minute, or millimeters per minute in metric. This is the normal milling mode and cancels G93.
Format
How it works
Modal, feed group 05. Default mode.
Example program
G01 Z-.1 F10. (10 INCHES PER MINUTE)
X2. F20. (20 INCHES PER MINUTE)
Example is in inch. Check offsets and clearances first.
Watch out for
- Put G94 in the safe start so an old G93 or G95 does not stay active.
On lathes: End facing cycle
Faces one pass: feed in X, feed out in Z, rapid back to start. Add more Z values on the next lines for more passes. K adds a cone.
