Individual tooth
measurement
December 2001
The measuring tolerance is changed according to the following table:
Tool radius
Up to 30 mm
30 mm to 60 mm
60 mm to 90 mm
90 mm to 120 mm
MP6507=2: Constant probing feed rate
The probing feed rate remains the same, regardless of the tool radius. The
absolute measuring error grows proportionally with the size of the tool radius.

The TNC attempts to maintain the tolerance from MP6510.0 during the tooth
search for individual tooth measurement. At the same time MP6510.0 is used
to calculate the probing feed rate.
If the tolerance from MP6510.0 cannot be maintained during the tooth search,
e.g. due to the missing spindle accuracy, the TNC attempts to maintain the
tolerance from MP6510.1. If this also cannot be maintained, the error
message Tolerance in MP6510 too small appears.
