<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>:
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.
STRING
The first substring must always be available, and can either
comprise one or two characters. The first or only character for
the 1st component (Val ) and the second character for the 2nd
1
component (Val ), which are processed according to the sub‐
2
sequent parameters <CorComp> and <CorMode>.
Charac‐ Adapter or tool base dimension (whichever
C

for the tool in use)

G
Sum offsets
S
Wear
W
The second substring is optional. Alternatively, it can comprise
(individual) letters "W" or "T".
Charac‐ If the second substring is empty or contains
W
ters: the letter "W", then the offset values are
taken into account as if they had been
measured in the workpiececoordinate sys‐
tem (WCS).
If the second substring contains the letter
T
"T", then the offset values are taken into
account as if they had been measured in
the toolcoordinate system (Tool Coordinate
System, TCS).
