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:
$TC_DP3[1,1]
: 10.000 ; Geometry L1 (unchanged)
$TC_DP4[1,1]
: 15.000 ; Geometry L2 (unchanged)
$TC_DP5[1,1]
: 10.000 ; Geometry L3 (unchanged)
$TC_DP12[1,1]
: 2.010 ; Wear L1
;(= 10 -15*cos(30) + 10*sin(30))
$TC_DP13[1,1]
: -16.160 ; Wear L2
;(= -15*sin(30) - 10*cos(30))
$TC_DP14[1,1]
: -5.000 ; Wear L3
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:

data:
MD20360 $MC_TOOL_PARAMETER_DEF_MASK (definition of tool parameters).
