Abstract:
The invention provides a control apparatus for a machine tool, which can perform reciprocating vibration in consideration of a vibration frequency, increase flexibility in machining a workpiece, and perform vibration cutting by means of an external spindle or the like without rotating a spindle. The control apparatus and the machine tool include control means. The control means includes an imaginary spindle regarded as a spindle for rotating a workpiece W or a cutting tool. The control means sets the number of rotations of the imaginary spindle and the number of reciprocating vibrations in accordance with a vibration frequency attributable to a cycle during which an operation instruction can be issued.

Claim (Index 19):
A machine tool comprising:\n a cutting tool configured to cut a workpiece; rotating means configured to rotate the cutting tool and the workpiece relative to each other; feeding means configured to feed the cutting tool and the workpiece in a predetermined feeding direction; vibration means configured to allow relative reciprocating vibration between the cutting tool and the workpiece; and a control apparatus including control means configured to perform cutting of the workpiece by feeding the cutting tool with reciprocating vibration toward the workpiece, wherein the control means includes an imaginary spindle regarded as a spindle for rotating the workpiece or the cutting tool, and the control means is configured to set the number of rotations of the imaginary spindle and the number of vibrations of the reciprocating vibration during one rotation of the imaginary spindle in accordance with the vibration frequency of the reciprocating vibration.
