CNC Machinist Calculator UltraG61 Exact stop mode
Fanuc G-code · Mill
Every move slows down and stops at its end before the next starts. Gives sharp corners at the cost of time.
Format
G61
How it works
Modal, group 15. Cancel with G64, G62 or G63.
Example program
G61 (EXACT STOP MODE ON)
G01 X2. Y1. F30. (SHARP CORNER HERE)
G64 (BACK TO CUTTING MODE)
G01 X2. Y1. F30. (SHARP CORNER HERE)
G64 (BACK TO CUTTING MODE)
Example is in inch. Check offsets and clearances first.
Watch out for
- Adds cycle time on programs with many short moves.
- Use G09 if only a few corners need it.
