A controller of a machine tool includes a plurality of feed axes that feed a tool, machines a workpiece while making the tool oscillate and includes: an oscillation command creation unit which creates an oscillation command based on a machining condition; and a control unit which machines, based on the oscillation command and a movement command, the workpiece while making the tool oscillate, and the oscillation command creation unit creates, when the machining condition indicates machining by an interpolation operation of one feed axis of the plurality of feed axes, the oscillation command so as to make the tool oscillate in a direction along a machining path and changes, when the machining condition indicates machining by a simultaneous interpolation operation of the plurality of feed axes, the oscillation command so as to change the direction of the oscillation with respect to the machining path.

Disclosed is a machining center. The machining center includes a bed structure deflected along a deflection curve by a load distribution thereon, a palette structure secured to a first end portion of the bed structure, a spindle assembly to which a machining tool is secured and secured to a second portion of the bed structure, a table movably secured to the bed structure such that a table loading is applied to a load point of the bed structure and an automatic aligner automatically detecting first and second installation errors of the table and the spindle assembly and automatically correcting the first and the second installation errors such that the workpiece and the tool are aligned with each other. The misalignment between the workpiece and the tool is automatically detected and corrected in the machining center.

A shot treatment apparatus ejects shot material from a nozzle towards a workpiece, and has the nozzle; a nozzle moving mechanism; and a three-dimensional information obtaining sensor; a pattern storage portion storing a nozzle reference operation pattern when the workpiece is installed at a reference position and a reference pose within the treatment compartment; a model data storage portion storing workpiece three-dimensional model data; a position/pose displacement calculating portion comparing the position and pose information and reference position and pose data when the three-dimensional model data is at the reference position in the reference pose to calculate a displacement in a position and pose of the workpiece from the reference position and pose data; and a nozzle movement control portion correcting the pattern based on the displacement in the position and pose, and controlling the nozzle moving mechanism to move the nozzle based on the corrected pattern.

To change or update each operating pattern and/or an operating condition according to a workpiece feeding state and/or an operating state of a robot. A workpiece transfer system includes: a workpiece infeed device for feeding a workpiece; a robot for transferring the workpiece being fed; a control device for selecting an operating condition of the robot based on a condition related to the workpiece and/or a condition related to the robot, the control device including a storage unit in which plural operating conditions are stored and a selection unit for selecting, as the operating condition of the robot, an optimum operating condition out of the plural operating conditions.

A machine system includes a transport control section which controls transport of a workpiece based on a transport deceleration line provided upstream of an operation limit line of a machine in a direction of travel of the workpiece and a transport acceleration line provided upstream of the transport deceleration line, wherein the transport control section reduces a transport speed of the workpiece when the workpiece passes through the transport deceleration line in an incomplete operation state and increases the transport speed of the workpiece after the operation on the workpiece present between the operation limit line and the transport acceleration line has completed.

A universal rotating chuck system capable of accommodating multiple small-batch or one-off machining jobs, involving workpieces of different diameter and composition, comprises a rotating chuck having multiple jaws that may be adjusted positionally inward or outward towards the longitudinal centerline of the workpiece or removed entirely. The chuck is rotated by a dual-motor system driving an inner and outer shaft, where the inner shaft is selectively coupled to the outer shafts to rotate independently and adjust the jaws, or rotate alongside the outer shaft to rotate the chuck. In operation, the system is capable of conducting numerous machining operations independent of direct user intervention, including loading/unloading workpieces, loading/unloading tools, measuring tools and workpieces for quality control, and storage.

An automated workpiece conveying vehicle included in a conveyance system that conveys a workpiece to each of a plurality of processing apparatuses is provided. The automated workpiece conveying vehicle includes: a workpiece support part that supports the workpiece; a traveling mechanism provided on the workpiece support part; a vibration detection unit that detects vibration of the workpiece support part and records the vibration as vibration data; and a receiver that receives a control signal transmitted from a control unit included in the conveyance system, the control signal instructing conveyance of the workpiece to the processing apparatus.

A control device of a processing machine controls a first drive source based on detection values from a first sensor so that a reference workpiece other than a workpiece is processed from a first direction by a tool into a prescribed target shape. The control device measures a shape of the reference workpiece based on a detection value from the first sensor at the time when contact in the first direction of a touch sensor with the processed reference workpiece by the touch sensor. The control device specifies a first deviation amount of a position of the tool in the X-direction based on a deviation amount in the first direction between the target shape and the measured shape, and corrects control for processing the workpiece based on the specified first deviation amount.
