摘要： Provided is a machine tool control device that can realize a desired scrap length while suppressing deterioration in machining accuracy. This control device 1 is for a machine tool which performs machining while causing a tool and a workpiece to oscillate relative to each other, the control device 1 being provided with: an oscillation command generation unit 13 for generating an oscillation command on the basis of an oscillation condition; an oscillation command correction unit 14 for correcting the oscillation command so that main-axis phases in given oscillation phases are not identical to each other; and a position/speed control unit 18 for causing the tool and the workpiece to oscillate relative to each other on the basis of a superposition command generated by superposing the oscillation command corrected by the oscillation command correction unit 14 on a movement command.

摘要： A system for reprofiling a wheel set of a railway vehicle allows the center of rotation of the wheel set to move relative to supporting rollers. A cutting tool used to reprofile the wheel profile on a wheel set is moved relative to the center of rotation of the wheel set to maintain a constant distance between the center of rotation and the cutter. The rollers are maintained in a fixed position during the cutting process. The system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.

摘要： A control apparatus for machine tool, in accordance with user set conditions, feeds a cutting tool in a feeding direction while reciprocatively vibrating the cutting tool, smoothly cuts a workpiece, and achieves a machined surface having an improved appearance. In a machine tool and a control apparatus thereof, a control means is configured to set the number of rotations of relative rotation and the number of vibrations of reciprocating vibration during one rotation of the relative rotation in accordance with a vibration frequency attributable to a cycle during which an operation instruction can be issued, and the control means includes adjusting means configured to adjust the number of rotations or the number of vibrations set by the control means.

摘要： This invention provides a machine tool that, in addition to sequentially separating a chip generated from a workpiece in a reliable manner, improves the roundness of the finished workpiece and improves the visual appearance and roughness of a machined surface of the workpiece, and a control apparatus of the machine tool. A machine tool or a control apparatus thereof includes a vibration frequency setting unit for setting vibration frequency of the reciprocal vibration with respect to one relative rotation when machining a workpiece so that the intersections of paths of a cutting tool during forward movement and backward movement are dispersed on a circumferential surface of the workpiece.

摘要： A machine tool and a control apparatus thereof include an amplitude control unit to control the amplitude of reciprocal vibration by a vibration unit. The amplitude control unit is configured to reduce the amplitude of the reciprocal vibration by the vibration unit as a cutting tool is fed in a feeding direction when the cutting tool reaches a predetermined cutting tool work stopping position on a workpiece in the feeding direction (Z-axis direction) to prevent the cutting tool from cutting the workpiece beyond the cutting tool work stopping position.
