3 <CorComp>: Specifies the component(s) of the tool data sets that are to be described (optional).
Data type: INT
Value: 0 Offset value <CorVal>[0] refers to the geometry axis transferred
in parameter <GeoAx> in the workpiece coordinate system – or
in the tool coordinate system (also see a description of param‐
eter <Comp>). This means that the offset value must be calcu‐
lated in the designated tool components so that, taking account
all the parameters that can influence the tool length calculation,
a change of the total tool length by the specified value in the
specified axis direction is obtained.
This change should be achieved by correcting the component
specified in <Comp> and the symbolic algorithm specified in
<CorMode> (see the following parameters). The resulting cor‐
rection can therefore have an effect on all three axis compo‐
nents.
1 Like "0", however, vectorial. The content of vector <CorVal>
refers to abscissa, ordinate and applicate in the workpiece co‐
ordinate system or tool coordinate system (see the description
of parameter <Comp>).
Subsequent parameter <GeoAx> is not evaluated.
2 Vectorial offset, i.e. L1, L2 and L3 can change simultaneously.
In contrast to the versions from "0 and "1", the offset values
contained in <CorVal> refer to the coordinates of Val
1
compo‐
nents (see following parameter <CorMode>) of the tool.
Any possible inclination of an existing tool compared with the
workpiece coordinate system has no influence on the offset.
3 - 5 Correction of tool lengths L1 to L3 ($TC_DP3 to $TC_DP5) or
the corresponding values for wear, setting up or additive offsets.
The offset value is contained in <CorVal>[0]. It is measured in
the coordinates of the Val
1
component (see following parameter
<CorMode>) of the tool. Any possible inclination of an existing
tool compared with the workpiece coordinate system has no
influence on the offset.
6 Correction of the tool radius ($TC_DP6) or the corresponding
values for wear, setting up or additive offsets. Bits 10 and 11
(evaluation of the diameter and/or diameter wear data, either
specified as a radius or diameter) in machine data
MD20360 $MC_TOOL_PARAMETER_DEF_MASK are taken
into account.
7
– 11
Correction of $TC_DP7 to $TC_DP11 or the corresponding val‐
ues for wear, setting up or additive offsets. These parameters
are treated just like the tool radius.
If this parameter is not specified then its value is "0".
