Functionality of the individual wear values

TOWSTD
Initial setting (default behavior):
• The wear values are added to the other tool length components.
In the case of an active toolholder with orientation capability:
• The wear values are subjected to the appropriate rotation.
TOWMCS
Wear data in the MCS (machine coordinate system):
In the case of an active rotation by means of a toolholder with orientation capability:
• The toolholder only rotates the vector of the resultant tool length. Wear is ignored.
If no toolholder with orientation capability is active or this does not result in a rotation,
TOWMCS and TOWSTD are identical.
162
Coordinate system for the evaluation of tool lengths
The resulting total tool length is then used in further calculations.
Then the tool length vector rotated in this way and the wear are added. The wear is not
subjected to the rotation.
