TR Reference tool for residual material
D Cutting edge of reference tool (1 or 2)
Z0 Reference point in Z direction (abs.)
Z1 Depth with reference to Z0 (abs. or inc.)
DXY Maximum infeed in the XY plane
Plane infeed in %: Ratio of plane infeed (mm)

DZ Maximum depth infeed (Z direction)
UXY Finishing allowance in plane
UZ Finishing allowance in depth
Retraction If more than one approach point is necessary, specify the retraction height to which
mode the tool retracts between approach points.
If there are no spigots or other elements larger than Z0 in the machining area, "Z0 +
safety clearance" can be selected as the retraction mode.
