G641 Continuous path with rounding distance
Siemens 840D 828D G-code · Mill and lathe
Continuous path mode where block transitions are rounded within a programmed distance. ADIS= applies to feed moves and ADISPOS= to rapid moves.
Format
G641 ADIS= ADISPOS=
Addresses
| Address | What it does |
|---|---|
ADIS= | Rounding distance for G1, G2 and G3 moves |
ADISPOS= | Rounding distance for G0 moves |
How it works
Modal, G group 10 (exact stop or continuous path).
Example program
G641 ADIS=0.05 ; ROUND CORNERS BY 0.05 MM MAX
G1 X50 Y0 F2000
X50 Y30
G60 ; EXACT STOP FOR NEXT CORNERS
G1 X50 Y0 F2000
X50 Y30
G60 ; EXACT STOP FOR NEXT CORNERS
Example is in inch. Check offsets and clearances first.
Watch out for
- Large ADIS values cut off corners. Keep it smaller than the part tolerance.
- Without ADIS= the rounding distance is zero and the path behaves like G64.
