Title:
工作機械の制御装置
Document Type and Number:
Japanese Patent JP6748140
Kind Code:
B2
Abstract:
To provide a controller for a machine tool capable of shredding chips without use of oscillation during machining by cutting. A controller is for a machine tool used for machining by cutting of a work as a cutting target by means of coordinated motion of multiple axes including at least a spindle axis. The controller comprises: a movement command generation unit that outputs a movement command for cutting the work by moving a cutting tool and the work relative to each other in a machining direction; and a stop determination unit that outputs a stop instruction for intermittently stopping the relative move in the machining direction to the movement command generation unit. The movement command generation unit outputs a movement command for stopping the relative move between the cutting tool and the work in the machining direction based on the stop instruction. The stop determination unit outputs the stop instruction for a period when the spindle axis rotates 360 degrees or more.
