Measurement of tool diameter (measurement type 11)

Tool diameter measurement on a reference part ($AC_MEAS_TYPE = 11)
The tool diameter 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.
