It is mounted on the turret and used for gauging the parts during the automatic cycle. The values identified by a probe are transmitted to the NC for a control with the programmed data. The transmission of the signal is made by an inductive way. The gauging cycle, depending on the type of use to be made, can envisage:
- No correction for the minimum values obtained.
- Correction of the part program according to the values programmed.
- Replacement of the tools with other ones, if present in the turret, when exceeding the values.
- Cycle stop.
