CONTROL DEVICE FOR MACHINE TOOL AND MACHINE TOOL INCLUDING THE CONTROL DEVICE

摘要

To provide a machine tool and a control device for the machine tool that can smoothly cut a workpiece while segmenting chips by feeding a cutting tool in a feed direction while reciprocally vibrating the cutting tool along the feed direction on the basis of a condition set by a user. The machine tool (100) or the control device (C) includes the control section (C1) that determines a number of rotations of the relative rotation and a number of vibrations of the reciprocal vibration per rotation of the relative rotation when the workpiece (W) is machined in accordance with a vibration frequency dependent on a period in which an operating instruction can be executed.

1. A control device for a machine tool provided in a machine tool having cutting tool for cutting a workpiece, a rotating unit for relatively rotating the cutting tool and the workpiece, a feeding unit for feeding the cutting tool and the workpiece in a predetermined feed direction, and a vibration unit for relatively reciprocally vibrating the cutting tool and the workpiece,
the control device control section to make the machine tool machine the workpiece via the relative rotation of the cutting tool and the workpiece and via the feeding of the cutting tool in the feed direction to the workpiece with the reciprocal vibration, wherein the control section determines a number of rotations of the relative rotation and a number of vibrations of the reciprocal vibration per rotation of the relative rotation when the workpiece is machined in accordance with a vibration frequency dependent on a period in which an operating instruction can be executed.
