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.

Presets in the machine

You define the tool tip with the following columns of the tool management relative to the tool carrier reference point:

  • L
  • DL

Tool carrier reference point

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.

Input coordinate system I-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:

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.
