Measurement of a groove (measurement type 12)

Measuring points for determining the position of a groove ($AC_MEAS_TYPE = 12)
A groove is measured by approaching the two outside corners or inner edges. The groove
center can be set to a setpoint position. The component of the approach direction determines
the groove position.
