摘要： A numerical control apparatus includes: a drive unit controlling a main shaft rotating a workpiece, a first drive shaft feeding a cutting tool relatively to the workpiece along a perpendicular direction to a lead direction of a thread, and a second drive shaft feeding the cutting tool relatively to the workpiece along the lead direction; and a vibration unit superimposing, on movement of the first drive shaft, vibration having a period having a predetermined ratio with a rotation period of the main shaft, and forms a thread on the workpiece by moving the cutting tool and the workpiece relative to each other and performing cut processes on the workpiece. The numerical control apparatus includes a thread-cutting vibration adjustment unit controlling the drive unit to shift phase of the vibration with respect to phase of the main shaft by a predetermined vibration phase shift amount every time in the cut processes.

摘要： A numerical control device is for machining a machining object by moving a tool and the machining object relative to each other along a movement path while applying vibration, by use of a drive axis provided for the tool or the machining object. The device includes a storage unit that holds an invalid frequency region, and a vibration condition determining unit to determine a frequency for the vibration, based on a rotational speed of a main shaft for rotating the machining object, a number of vibrations of the vibration in each one rotation of the main shaft, and the invalid frequency region.

摘要： A machining time calculating apparatus calculates operation schedule information indicating the operation time of each of a plurality of systems that is included in a machine tool and can be controlled independently of one another. The machining time calculating apparatus includes a system cycle time calculation unit. On the basis of wait commands among the plurality of systems described in a machining program (PG) for the machine tool, the system cycle time calculation unit calculates the operation schedule information in which the operation start times of blocks in the machining program of each of the systems are adjusted while maintaining wait timings among the plurality of systems.
