摘要
In connection with a machining program used in machining a workpiece by means of a machine tool controlled by a numerical controller, interpolation data, a command position point sequence, and a servo position point sequence for each processing period are determined by simulation by designating speed data for giving a machining speed and precision data for giving a machining precision. A predicted machining time for workpiece machining is determined based on the determined interpolation data, and a predicted machining error for workpiece machining is determined based on the determined command and servo position point sequences. Further, the precision data and the speed data are determined for the shortest predicted machining time within a preset machining error tolerance, based on a plurality of predicted machining times and a plurality of predicted machining errors.
