Radius Machining to the left of the contour
compensation
Machining to the right of the contour
Machining along the center path
Machining type Roughing
Finishing
Chamfer
Machining Forward: machining is performed in the programmed contour direction
direction Backward: machining is performed in the opposite direction to the programmed
contour
Z0 Reference plane (abs. or inc.)
Z1 End depth (abs. or inc.) (not for chamfer)
DZ Infeed depth (not for chamfer)
FS Chamfer width (for chamfer only), inc.
ZFS Insertion depth tool tip (for chamfer only), abs. or inc.
UZ Finishing allowance base (not for chamfer)

You can choose between planar approach/retraction and spatial
approach/retraction:
• Planar approach:
• Spatial approach:
• Retraction is performed in reverse order.
Mixed programming is possible, for example, approach in the
plane, retract spatially.
A programmed contour can also be machined along the center-point
path if the operation has been activated under radius compensation
(no radius compensation)
is only possible along a straight line or vertical. Vertical
approach/retraction can be used for closed contours, for example.
