Tool coordinate system T-CS
Application
In the tool coordinate system T-CS the control implements tool compensations and tool inclinations.
Description of function
Properties of the tool coordinate system T-CS
The tool coordinate system T-CS is a three-dimensional Cartesian coordinate system. Its coordinate origin is the tool tip TIP.
You make entries in the tool management to define the tool tip relative to the tool carrier reference point. The machine manufacturer usually defines the tool carrier reference point on the spindle tip.
You define the tool tip with the following columns of the tool management relative to the tool carrier reference point:
- L
- DL
You use positioning blocks in the input coordinate system I-CS to define the position of the tool and therefore the position of the T-CS.
You can use miscellaneous functions to also program in other reference systems, such as M91 for the machine coordinate system M-CS.
Traversing in the machine coordinate system M-CS with M91
The orientation of the T-CS in most cases is identical to that of the I-CS.
If the following functions are active, the orientation of the T-CS depends on the tool angle of inclination:
- Miscellaneous function M128 (#9 / #4-01-1)
Compensating the tool angle of inclination automatically with M128 (#9 / #4-01-1)
- The FUNCTION TCPM function (#9 / #4-01-1)
Compensating the tool angle of inclination with FUNCTION TCPM (#9 / #4-01-1)
Use the miscellaneous function M128 to define the tool angle of inclination in the machine coordinate system M-CS using axis angles. The effects of the tool angle of inclination depend on the machine kinematics:

You can also define a tool angle of inclination in the working plane coordinate system WPL-CS, for example with FUNCTION TCPM or a straight line LN.

Transformations in the tool coordinate system T-CS
The following tool compensations have an effect in the tool coordinate system T-CS:
- Compensation values from the tool management
- Compensation values from the tool call
- Values of the compensation tables *.tco
- 3D tool compensation with surface normal vectors (#9 / #4-01-1)
