Abstract

PURPOSE: To measurably hold a workpiece, after it is worked, so as to immediately decide the workpiece for whether it is good or bad by providing a detecting means, having a force sensor for detecting reaction force of a measured part by pressing it by the predetermined dimension to generate the elastic deformation, and a comparing means for comparing the detected reaction force with the reference value.
CONSTITUTION: A workpiece 1 after turning work is held to a chuck 18 in the point end of a spindle 16 movable in a direction Z. A force sensor 27, which is fixed to a tool rest 25 on an X-axis table 23, can be attached to the workpiece 1. First by pressing the force sensor 27 to a point end 1a of the workpiece 1, a thin thickness part 4 is elastically deformed, and reaction force F corresponding thereto is generated. The reaction force F is output as a voltage value and judged for whether it is reference voltage or not in a comparator 53, and the voltage value, when it is within the range, is output to an NC work data processor 50. When the voltage value is out of the range, turning by a tool 26 of the tool rest 25 is commanded. Here the workpiece, left as held, can be measured and decided for whether the workpiece is good or bad, and inferior products can be reduced.
