The geometry component of the tool remains unchanged due to _CORMODE = 1. The compensation vector
defined in the WCS (rotation about y axis) must be included in the wear component such that the total tool length
in the figure refers to point P
2
. Therefore, the resulting wear component of the tool is given in relation to the
distance between points P
1
and P
2
.
However, since the wear is evaluated negatively, due to setting data SD42930, the compensation determined in
this way has to be entered in the compensation memory with a negative sign. The contents of the relevant tool
parameters at the end of the program are thus:
The effect of setting data SD42930 on the L3 component in the Y direction can be recognized without the
additional complication caused by the frame rotation.
Example 9:
2 (tool length must be valued in the diameter axis with the factor 0.5) is the value of machine data:
MD20360 $MC_TOOL_PARAMETER_DEF_MASK (definition of tool parameters).
X is diameter axis:
