Abstract
A control device that causes multiple systems included in a machine tool to operate independently of each other according to NC programs, which are multiple machining programs associated with the multiple respective systems, includes a shaft feeding speed determination unit that adjusts a feed shaft moving speed of a speed-adjusted system when one of the multiple systems is set as a system under monitoring, where the speed-adjusted system is a system other than the system that has been set as the system under monitoring.
Claims7
A control device that causes a plurality of systems included in a machine tool to operate independently of each other according to a plurality of machining programs associated with the plurality of respective systems, the control device comprising:
- shaft feeding speed determination circuitry to adjust a feed shaft moving speed of a speed-adjusted system by multiplying a feed speed by an override setting value described in an applicable one of the machining programs associated with the speed-adjusted system, the speed-adjusted system being one of the systems in which the feed shaft moving speed is adjusted on a basis of an operational state of a system under monitoring, when one of the plurality of systems is set as the system under monitoring by a command described in an applicable one of the machining programs associated with the one of the systems, and another one of the systems other than the system that has been set as the system under monitoring is set as the speed-adjusted system by a command described in the applicable one of the machining programs associated with the another one of the systems.
A machine tool control method for controlling a machine tool, to be implemented by a control device that causes a plurality of systems included in the machine tool to operate independently of each other according to a plurality of machining programs associated with the plurality of respective systems, the machine tool control method comprising:
- adjusting a feed shaft moving speed of a speed-adjusted system by multiplying a feed speed by an override setting value described in an applicable one of the machining programs associated with the speed-adjusted system, the speed-adjusted system being one of the systems in which the feed shaft moving speed is adjusted on a basis of an operational state of a system under monitoring, when one of the plurality of systems is set as the system under monitoring by a command described in an applicable one of the machining programs associated with the one of the systems, and another one of the systems other than the system that has been set as the system under monitoring is set as the speed-adjusted system by a command described in the applicable one of the machining programs associated with the another one of the systems.
