Relevant setting data

SD42900-42960
Setting data SD42900-SD42940 can be used to make the following settings with reference to
tool compensation:
• 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
