Information contained in variables
The following variable information on tool data and your NC program
can be read out. The assignment of variables #518..#521 varies
depending on the type of tool.
Precondition: The variable is ”defined” as a result of a tool call or an
NC program call.
# variables Information on tool data

Positions and dimensions are always
indicated in metric form. This also applies
when an NC program is run in inches.
Primary and secondary machining direction:
0: undefined
1: + Z
2: + X
3: – Z
4: –X
5: +/– Z
6: +/– X
