5.8 Programmable tool offset (TOFFL, TOFF, TOFFR)

5.8 Programmable tool offset (TOFFL, TOFF, TOFFR)
Function
The user can use the commands
the effective tool radius in the NC program, without changing the tool offset data stored in the
compensation memory.
These programmed offsets are deleted again at the end of the program.
Tool length offset
Depending on the type of programming, programmed tool length offsets are assigned either
to the tool length components L1, L2 and L3 (
