Coordinate systems for offsets in tool length
G codes TOWMCS, TOWWCS, TOWBCS, TOWTCS and TOWKCS can be used, e.g. to measure the wear tool length
component in five different coordinate systems.
The calculated tool length or a tool length component can be represented and read out in one of these coordinate
systems using the GETTCOR function (predefined subprogram).

TOWSTD
Initial setting (default behavior):
• The wear values are added to the other tool length components.
The resulting total tool length is then used in further calculations.
In the case of an active toolholder with orientation capability:
• The wear values are subjected to the appropriate rotation.
