-13: The content of the _GEOAX parameter does not designate a geometry axis.
-14: Write attempt to a non-existent setup offset.
_CORVAL[3] REAL array
Designates the offset vector.
In this case, in the workpiece coordinate system (WCS) defined using _STAT the
following are assigned:
• _CORVAL[0] of the abscissa
• _CORVAL[1] of the ordinate
• _CORVAL[2] of the applicate
If only one tool component is to be corrected (i.e. no vectorial correction, see parameter
_CORMODE), the correction value is always in _CORVAL[0], independent of the axis on
which it acts. The contents of the other two components are then not evaluated.
If _CORVAL or a component of _CORVAL refers to the transverse axis, then the data is
evaluated as radius dimension. This means that a tool is e.g. "longer" by the specified
dimension; this correspondingly results in a change to the workpiece diameter that is
twice as large.
The dimensions refer to the basic system (inch or metric) of the control system.
_COMP STRING
String that comprises either one or two characters. The first or only character for the 1st
component (Val
1
) and the second character for the 2nd component (Val
2
), which are
processed according to the subsequent parameters _CORCOMP and _CORMODE.
The notation of the characters in the string (upper or lower case) is arbitrary. Any
number of spaces or tabs (white spaces) can be inserted.
The individual meanings are as follows:
C: Adapter or tool base dimension (whichever of the two alternative components is
active for the tool in use)
E: Setup offsets
G:Geometry
S: Sum offsets
W:Wear
_CORCOMP INT
This parameter specifies the component(s) of the two data sets that are to be described.
If this parameter is not specified then its value is 0.
