Process for coordinate measurement on workpieces |
摘要 |
A sensor in the probe head of a coordinate measuring device supplies probe signals. The first, and if necessary, higher time derivatives of the probe signals are formed and evaluated for the exact determination of the moment of contact of the probe head with a workpiece to be measured. During the evaluation, the time course of the differentiated signals is examined by means of automatically generated trigger thresholds.
