Further information
Determine tool length compensation from the orientation of the toolholder (TCOABS)
TCOABS calculates the tool length compensation from the current orientation angles of the
toolholder; saved in the system variables $TC_CARR13 and $TC_CARR14.
For a definition of toolholder kinematics with system variables, see "Toolholder kinematics
(Page 503) ".
In order to make a new calculation of the tool length compensation when frames are
changed, the tool has to be selected again.
Tool direction from active frame
The toolholder with orientation capability is set so that the tool points in the following
directions.
● with TCOFR or TCOFRZ in the Z direction
● with TCOFRY in the Y direction
● with TCOFRX in the X direction
The tool length compensation is re-calculated when changing over between TCOFR and
TCOABS.
