加工物の位置検出装置。A workpiece equipped with an electric circuit and display means for detecting contact between a detection rod mounted in an electrically insulated manner on a tool mounting shaft of a processing machine and a workpiece placed on a processing table. In the object position detection device, the electric circuit includes an oscillation circuit, and the alternating output from the oscillation circuit reduces the electrostatic capacitance generated between the detection rod and the workpiece before they come into contact with each other. 1. A position detection device for a workpiece in a metal processing machine, comprising: a circuit for detecting a change in capacitance; and display means for displaying a detected change in capacitance.
