Detailed Description
2.10 Working with tool environments
MD20360 $MC_TOOL_PARAMETER_DEF_MASK
The two least significant bits of this machine data specify how the wear (bit 0) and tool length
(bit 1) are to be evaluated if a diameter axis is used for turning and grinding tools.
If the bits are set, the associated entry is weighted with the factor 0.5. This weighting is
reflected in the tool length returned by GETTCOR.
Example:
MD20360 $MC_TOOL_PARAMETER_DEF_MASK = 3 (definition of tool parameters).
MD20100 $MC_DIAMETER_AX_DEF="X" (Geometry axis with face axis funtion)
X is diameter axis (standard turning machine configuration):
