Step=by=step workpiece machining system - carries out measurement after each step and uses results to control next step

摘要

The machining takes place in stages in subsequent machining station, esp. as regards honing of bores. After each honing station a measurement is taken, the result being used for the control of the the operation of the next preset station in machining of the following workpiece. The measuring results of at least one machining pass are used for the control of the following honing station. Pref. at least one honing station is controlled by both a following and a previous measuring stations, i.e. by the differential values of these stations. At least one measuring station may provide a different forward and rearward effect. This station may carry out measuring at several points of the bore. The control system of the machining arrangement contains a comparator for signals of both measuring stations, which controls the honing station in response to the difference of both signals.
