Parameters
| Parameter | Description |
|---|---|
| X,Y | pocket center coordinates. |
| K | pocket diameter (negative = clockwise cutting). |
| Q | internal diameter. |
| I | stock allowance (default value I=0). |
| J | distance between passes in tool radius units (default value J=1.6). |
| D0 | machining mode selection: D0=0 concentric cuts and Z – increment only (default). D0=1 spiral path cuts and Z – increment only. D0=2 spiral path cuts and X, Y, Z – increment. |
| D1= | pocket starting depth. |
| D2= | pass depth. |
| D3= | pocket bottom depth. |
| D4= | clearance distance (default value D4=2 mm). |
| D5= | radius value for tool automatic approach and exit during the finish pass (default value D5=I).. |
| D6= | wall taper rate (default value D6=0- vertical wall). |
| D7= | percentage of feed rate variation during depth increment (default value D7=1). |
| D9= | clearance value from pocket walls during tool repositioning at end of cycle (D9=0.5mm by default). |
