DISLOCATION-OF-FEEDING-SHAFT MONITORING METHOD OF NC MACHINE TOOL

摘要

PURPOSE: To enable accurate and high-efficient' machining by setting optimum allowable values to the dislocation of the feeding shaft of n NC machine tool in accordance with the degree of machining such as finish machining, intermedi ate and rough machining. ;CONSTITUTION: The dislocation (c) between the command position of the feeding shaft that is defined on the basis of the machining command information from an NC device 20 and the actual position that is detected by an encoder 109 is obtained, and a plurality of dislocation allowable values W, T1, and T2 that have been determined in accordance with the degree of machining are set, and when the detected dislocation (4e) exceeds the set allowable value, warning, alarm, and the like are output.;COPYRIGHT: (C)1993,JPO&Japio
