Tool length components (optional)
<Comp>:
Data type:
The character string consists of two substrings, which are separated from one
another by a colon.
General form: "<SubStr_1> [: <SubStr_2]"
<SubStr_1>:
<Substr_2>:
Name of the data set for describing a tool environment (optional)
<_Stat>:
Data type:
If the value of this parameter is the null string (""), or is not specified, then the
current status is used. The current tool is used if a tool is not specified.
STRING
The first substring designates the tool length components to be
taken into account when calculating the tool length.
The order of the characters in the substrings, and their notation
(upper or lower case), is arbitrary. Any number of blanks or
white spaces can be inserted between the characters.
Note:
It is not permissible that the characters in the substring are pro‐
grammed twice.
Charac‐ Minus symbol (only allowed as first character)
-
ters:
The complete tool length is calculated, minus
the components specified in the next string.
Adapter or tool base dimension (whichever of
C
the two alternative components is active for the
tool in use)
Setup offsets
E
Geometry
G
Kinematic transformation (is only evaluated for
K
generic 3, 4 and 5-axis transformation)
Summed offsets
S
Toolholder with orientation capability
T
Wear
W
If the first substring is empty (except for white spaces), the com‐
plete tool length is calculated allowing for all components. This
applies even if the <Comp> parameter is not specified.
The optional second substring identifies the coordinate system,
in which the tool length is to be output.
The second substring only comprises one single relevant char‐
acter.
Charac‐ Adjustable coordinate system (ACS)
A
ters:
Basic coordinate system (BCS)
B
Tool coordinate system of kinematic transfor‐
K
mation (KCS)
Machine coordinate system (MCS)
M
Tool coordinate system (TCS)
T
Workpiece coordinate system (WCS)
W
If no coordinate system is specified, the evaluation is performed
in the MCS (machine coordinate system). If any rotations are to
be taken into account, they are specified in the tool environment
defined in <Stat>.
