Parameter
Description
Unit
Machining direction
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 con-
tour
Radius compensation
• 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 verti-
cal. Vertical approach/retraction can be used for closed contours, for example.
Slot side compensation
(only ShopTurn)
Slot side compensation on or off (only for machining surface, peripheral sur-
face C)
D Offset to programmed path
- (only for slot side compensation on)
CP Positioning angle for machining area
- (only for ShopTurn, machining surface, face Y)
Degrees
C0 Positioning angle for machining surface
- (only for ShopTurn, machining surface, peripheral surface Y)
Degrees
Z0
Reference point Z
mm
Z1
Final drilling depth (abs) or final drilling depth referred to Z0 or X0 (inc)
mm
DZ
Maximum depth infeed - (only for machining ∇ and ∇∇∇)
mm
UZ
Depth finishing allowance - (only for machining ∇)
mm
UXY
Finishing allowance, plane
mm
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)
