Stepless variation of the tool orientation
The toolholder with orientation capability also enables the tool orientation to be varied
steplessly, in addition to providing further offsets or linear expansion fluctuations with the aid
of offset vectors l

Minor operator compensations
Minor compensations, however, must also be modified during the normal production mode.
The reasons for this are e.g.:
• Tool wear
• Clamping errors
• Temperature sensitivity of the machine:
These compensations are defined as follows:
Definition Wear components
Wear $TC_DP12 - $TC_DP14,
Total offsets fine $TC_SCPx3 - $TC_SCPx5,
Sum offsets coarse or setup offsets $TC_ECPx3 - $TC_ECPx5
In particular, compensations, which affect the tool length calculation, should be entered in
the coordinates used for measurement.
These workpiece-specific compensations can be achieved more simply using the G-code
group 56 with the three values TOWSTD, TOWMCS and TOWWCS and the setting data:
SD42935 $SC_WEAR_TRANSFORM (transformation of tool components)
