Tool Length Compensation For Orientable Toolholders (Tcarr, Tcoabs, Tcofr, Tcofrx, Tcofry, Tcofrz) - Siemens SINUMERIK 840D sl Programming Manual

3.13.9 Tool length compensation for orientable toolholders (TCARR, TCOABS, TCOFR,
TCOFRX, TCOFRY, TCOFRZ)
When the spatial orientation of the tool changes, its tool length components also change.
Z
After a reset, e.g. through manual setting or change of the toolholder with a fixed spatial
orientation, the tool length components also have to be determined again. This is performed
using the TCOABS and TCOFR path commands.
For a toolholder of an active frame that can be orientated, when selecting the tool with TCOFRZ,
TCOFRY and TCOFRX, it is possible to define the direction in which the tool should point.
