Specifies the component(s) of the tool data sets that are to be described (optional).
<CorComp>:
Data type:
Value:
If this parameter is not specified then its value is "0".
INT
Offset value <CorVal>[0] refers to the geometry axis transferred
0
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.
Like "0", however, vectorial. The content of vector <CorVal>
1
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.
Vectorial offset, i.e. L1, L2 and L3 can change simultaneously.
2
In contrast to the versions from "0 and "1", the offset values
contained in <CorVal> refer to the coordinates of Val
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 $TC_DP5) or
the corresponding values for wear, setting up or additive offsets.
The offset value is contained in <CorVal>[0]. It is measured in
the coordinates of the Val
<CorMode>) of the tool. Any possible inclination of an existing
tool compared with the workpiece coordinate system has no
influence on the offset.
Correction of the tool radius ($TC_DP6) or the corresponding
6
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.
Correction of $TC_DP7 to $TC_DP11 or the corresponding val‐
7
– 11 ues for wear, setting up or additive offsets. These parameters
are treated just like the tool radius.
