Relevant setting data

SD42900- 42960
Setting data SD42900 - SD42940 can be used to make the following settings with reference to
tool offset:
● Sign of the tool length
● Sign of the wear
● Behavior of the wear components when mirroring geometry axes
● Behavior of the wear components when changing the machining plane via setting data
● Allocation of the tool length components independent of actual tool type
● Transformation of wear components into a suitable coordinate system for controlling the
effective tool length
Note
In the following description, the wear includes the total values of the following components:
● Wear values: $TC_DP12 bis $TC_DP20
● Sum offset, consisting of:
