2.7.2.2 Adding wear in surface normal direction
When the SURF_NORM_ORI processing type is used, it is possible to use automatic continuous wear
compensation and influencing via the PLC interface. The mode must be DISC or AUTO. The surface normal
is approximated based on the current tool orientation and path tangent (cf. RADIUS type). For a continuous
change in direction of the surface normal vector, the contour and orientation should be steady at all times.
The input of the first 3 axes is ignored All the axes in the following sequence can be influenced as usual by
the PLC.
OTC offset in tool direction
Description When this wear offset is set, wear in the direction of the tool axis can be
compensated. The offset value must be added to the third axis.
Special features Wear offset is adjusted by the CNC in the tool direction over several cycles.
