INTERFERENCE DETERMINATION METHOD AND INTERFERENCE DETERMINATION DEVICE FOR MACHINE TOOL

摘要

An interference determination method for machine tools which determines whether or not there will be interference between elements that move relative to each other, the method including: a setting procedure for setting a machine tool model obtained by combining the shape model of each of the elements including a work model corresponding to the work; a measurement procedure for measuring the position of the work attached to the work attachment part; a correction procedure for acquiring, at a predetermined timing, the position of the work measured in the measurement procedure, and correcting the machine tool model set in the setting procedure; and a determination procedure for determining whether or not there will be interference between the elements on the basis of the machine tool model corrected in the correction procedure.

1. An interference judgment method of a machine tool for judging a presence or absence of an interference between components of a machine tool when operating the machine tool according to a machining program, comprising:
a setting step of setting a machine tool model obtained by combining shape models of the components, the machine tool model including a workpiece model corresponding to a workpiece; a measurement step of measuring the workpiece mounted to a workpiece mounting part to determine a parameter relating to a workpiece coordinate system; a correcting step of reading the parameter relating to the workpiece coordinate system determined at the measurement step at a predetermined timing to correct the machine tool model set at the setting step; and a judgment step of judging the presence or absence of the interference between the components based on the machine tool model corrected at the correcting step.
