Parameter Description
Machining Machining in the programmed contour direction
direction
Forward:

Machining is performed in the programmed contour direction
Backward:

Machining is performed in the opposite direction to the programmed contour
Radius
Left (machining to the left of the contour)

compensation
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
approach/retraction can be used for closed contours, for example.
Slot side Slot side compensation on or off (only for machining surface, peripheral surface C)
compensation
(only ShopTurn)
D Offset to programmed path
- (only for slot side compensation on)
CP Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
C0 Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
Z0 Reference point Z
Z1 Final drilling depth (abs) or final drilling depth referred to Z0 or X0 (inc)
DZ Maximum depth infeed - (only for machining ∇ and ∇∇∇)
UZ Depth finishing allowance - (only for machining ∇)
UXY Finishing allowance, plane
Approach Planar approach mode:
Quadrant:

Part of a spiral (only with path milling left and right of the contour)
Semi-circle:

Part of a spiral (only with path milling left and right of the contour)
Straight line:

Slope in space
Perpendicular:

Perpendicular to the path (only with path milling on the center-point path)
