Parameter Description Unit
Machining
● ∇ (roughing)
● ∇∇∇ (finishing)
● Chamfering
Machining direc‐
tion
Machining in the programmed contour direction
● Forward:
Machining is performed in the programmed contour direction
● Backward:
Machining is performed in the opposite direction to the programmed contour
Radius compen‐
sation
● Left (machining to the left of the contour)
● Right (machining to the right of the contour)
● off
A programmed contour can also be machined on the center-point path. In this case,
approaching and retraction is only possible along a straight line or vertical. Vertical ap‐
proach/retraction can be used for closed contours, for example.
Z0 Reference point Z (abs or inc)
Z1 Final depth (abs) or final depth referred to Z0 (inc) - (only for ∇ and ∇∇∇) mm
DZ Maximum depth infeed - (only for ∇ and ∇∇∇) mm
UZ Depth finishing allowance - (only for ∇) mm
FS Chamfer width for chamfering (inc) - (for chamfering only) mm
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only) mm
UXY Finishing allowance, plane - (only for ∇ and G code, not for radius compensation off) mm
