Coordinate System Of The Active Machining Operation (Towstd/Towmcs/Towwcs/Towbcs/Towtcs/Towkcs) - Siemens SINUMERIK 840DE Programming Manual

SD 42930 WEAR_SIGN
Setting data not equal to zero:
the sign of all wear dimensions is inverted. This affects both the tool length and other
variables such as tool radius, rounding radius, etc.
If a positive wear dimension is entered, the tool becomes "shorter" and "thinner", see chapter
"Tool offsets, Special handling, Activation of changed setting data".
8.17.3 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.

Parameters
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.
1. Machine coordinate system (MCS)
2. Basic coordinate system (BCS)
3. Workpiece coordinate system (WCS)
4. Tool coordinate system (TCS)
5. Tool coordinate system of kinematic transformation (KCS)
