Kontaktdetektor für eine Werkzeugmaschine |
摘要 |
<p>A contact detecting system for detecting the contact of a tool element, supported by a main shaft of a machine, with a workpiece comprises exciting and detecting coil assemblies, an electric power source for supplying a high frequency electric current to the exciting coil assembly to cause the latter to produce an induction current flowing in a loop circuit constituted by the machine shaft, the tool element and a framework of the machine, and a detector unit for generating a detection signal indicative of the actual contact of the tool element with the workpiece when the detector unit has detected the presence of a current component, which has resulted from the induction current generated by the exciting coil assembly, in the output signal from the detecting coil assembly.</p> |
