8.14 Tool length compensation for orientable toolholders (TCARR, TCOABS, TCOFR)
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.
It is possible for an orientable toolholder of an active frame to determine the direction of the
tool when a tool is selected with TCOFRZ, TCOFRY, and TCOFRX.
