Automatic retract control method when an error occurs in the machining center

摘要

According to the present invention, when an error occurs during the machining of a workpiece in an automatic workpiece changer, a pallet magazine, or an FMS line of a machining center, it is possible to automatically retract (i.e., return to the origin of the machine and eject the workpiece) by identifying the error status. The present invention relates to an automatic retract control method when an error occurs in a machining center, which determines whether an error has occurred during workpiece machining (S5), and if so, stores the error state in memory (S11), The system is reset (S12), and a specific machining program is called (S13), and it is determined whether an error is caused by a tool break (S14). If a tool is broken, a broken tool is skipped so as not to be called again. After that (S15), the operator stores the interruption information in the memory so as to check the state of the workpiece later (S16), and determines whether the error state is pallet ejectable. (S17), if the discharging state, a characterized in that the return of each axis of the machine zero point to the next processing (S18), by discharging the workpiece (S29), automatic exchange of the workpiece (S4).
