7.3.3 Coordinate system of the active machining operation (TOWSTD, TOWMCS,
TOWWCS, TOWBCS, TOWTCS, TOWKCS)
Function
Depending on the kinematics of the machine or the availability of an orientable toolholder,
the wear values measured in one of these coordinate systems are converted or transformed
to a suitable coordinate system.
Coordinate systems of active machining operation
The following coordinate systems can produce tool length offsets that can be used to
incorporate the tool length component "wear" into an active tool via the corresponding G
code of Group 56.
● Machine coordinate system (MCS)
● Basic coordinate system (BCS)
● Workpiece coordinate system (WCS)
● Tool coordinate system (TCS)
● Tool coordinate system of kinematic transformation (KCS)
Syntax
TOWSTD

Significance
TOWSTD
Initial setting value for offsets in tool length wear value
TOWMCS
Offsets in tool length in MCS
TOWWCS
Offsets in tool length in WCS
TOWBCS
Offsets in tool length in BCS
TOWTCS
Offsets of tool length at toolholder reference point (orientable toolholder)
TOWKCS
Offsets of tool length at tool head (kinematic transformation)
