Abstract:
To provide a workpiece processing method that facilitates the detection and setting of a working standard of a workpiece.SOLUTION: A workpiece processing method includes a position detection jig, which holds a workpiece by an indexing-controlled main shaft and which is brought into press contact toward inner and outer peripheral surfaces or an end surface of the workpiece. In the workpiece, a recess for detecting a working standard is provided on the inner and outer peripheral surfaces or the end surface. The main shaft is rotated while the tip of the position detection jig is brought into contact with the inner and outer peripheral surfaces or the end surface of the workpiece. The tip of the position detection jig detects a phase of the main shaft inserted into the recess. Thus, an indexing position of the main shaft is set.SELECTED DRAWING: Figure 1
