Measuring and tool offset
5.4.3.1
General information
Function
Using this measuring cycle and the _MVAR = x0xx
measuring variant, a hole, shaft, groove, a web, or a rectangle can be measured paraxially.
Automatic tool offset is also possible. This tool is specified in _TNUM and _TNAME.
The D number and type of offset are specified in coded form in variable _KNUM.
From measuring cycles SW 6.3, extended tool offset is available. With this function a tool
from a particular stored tool environment _TENV, and additive, setup offsets can be
corrected by specifying the DL number in _DLNUM.
Detailed information on the parameters: see Parameter description section "Description of
the most important defining parameters".
If the dimensions of a tool are corrected to this extent, the next workpiece can be
manufactured with lower tolerances.
