Parameter Description
Machining
● ∇ (roughing)
● ∇∇∇ (finishing)
● Chamfering
Machining direc‐ Machining in the programmed contour direction
tion
● Forward:
Machining is performed in the programmed contour direction
● Backward:
Machining is performed in the opposite direction to the programmed contour
Radius compen‐ ● Left (machining to the left of the contour)
sation
● 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 ∇∇∇)
DZ Maximum depth infeed - (only for ∇ and ∇∇∇)
UZ Depth finishing allowance - (only for ∇)
FS Chamfer width for chamfering (inc) - (for chamfering only)
ZFS Insertion depth of tool tip (abs or inc) - (for chamfering only)
UXY Finishing allowance, plane - (only for ∇ and G code, not for radius compensation off)
