NUMERICAL CONTROL DEVICE

摘要

A numerical control device includes: a control unit controlling movement of shafts of a machine tool by a position command according to a machining program and acquiring position information on the shafts; a monitoring point determination unit determining a monitoring point in the machining program and a monitoring shaft according to the type of an instruction or an instruction related to travel described in the machining program; and a monitoring unit monitoring whether error or deviation based on the position information at the monitoring point of the monitoring shaft exceeds a predetermined threshold, wherein the control unit controls movement of the shafts based on the monitoring result of the monitoring unit, and the numerical control device further comprises an analysis unit presenting whether the cause of the error or deviation is a mechanical factor or a control factor based on the monitoring result and outputting the analysis result.

1. A numerical control device comprising:
a control unit that controls a movement of a plurality of shafts of a machine tool by a position command according to a machining program and acquires position information on the shafts; a monitoring point determination unit that determines a monitoring point, which is to be monitored, in the machining program and a monitoring shaft that is the shaft to be monitored, in accordance with a type of an instruction or an instruction related to a travel described in the machining program; and a monitoring unit that monitors whether an error or a deviation based on the position information at the monitoring point of the monitoring shaft exceeds a predetermined threshold, wherein the control unit controls a movement of the shafts on a basis of a monitoring result of the monitoring unit, and the numerical control device further comprises an analysis unit that presents whether a cause of the error or the deviation is a mechanical factor or a control factor on a basis of the monitoring result and that outputs an analysis result of the factor to an output unit.
