W1: Tool offset
18.11 Sum offsets and setup offsets
Minor operator compensations
Minor compensations, however, must also be modified during the normal production mode.
The reasons for this are, for example:
● Tool wear
● Clamping errors
● Temperature sensitivity of the machine:
These compensations are defined as follows:
Definition
Wear
Total offsets fine
Sum offsets coarse or setup offsets
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 $SC_WEAR_TRANSFORM (transformation of tool components)
SD42935
Which of the wear components:
● Wear ($TC_DP12 - $TC_DP14)
● Setup offsets or sum offsets coarse ($TC_ECPx3 - $TC_ECPx5)
● Sum offsets fine ($TC_SCPx3 - $TC_SCPx5)
are to be transformed in the transformations:
● Adapter transformation
● Toolholder with orientation capability
are to be or not to be transformed, can be defined via the setting data:
SD42935 $SC_WEAR_TRANSFORM (transformation of wear values)
With the setting data in its initial state, all wear values are transformed.
