Measurement of tool lengths (measurement type 10)

Tool length measurement on a reference part that has already been measured
($AC_MEAS_TYPE = 10)
The tool length can be measured on a reference part that has already been measured.
Depending on the position of the tool, it is possible to select plane G17 for tool position in the
z direction, G18 for tool position in the y direction and G19 for tool position in the x direction.
