Claim One:
1. A machine tool performance evaluation apparatus which is provided for an NC machine tool equipped with a numerical controller for controlling operation of a motion mechanism in accordance with an operation command signal, and which evaluates performance of said motion mechanism, comprising: analysis data storing means for storing three dimensional model data of said motion mechanism and condition data for performance analysis; detecting means for detecting actual performance of said motion mechanism of said NC machine tool; analyzing means for analyzing the performance of said motion mechanism, based on said operation command signal in said numerical controller and on the three dimensional model data of said motion mechanism and the condition data for performance analysis stored in said analysis data storing means; data accumulating means for storing actual performance data of said motion mechanism detected by said detecting means and performance analysis data analyzed by said analyzing means; and evaluation determining means for evaluating the correctness of said performance analysis data by comparing said performance analysis data with the actual performance data of said motion mechanism stored in said data accumulating means.
