Abstract: A workpiece machining device with a calibration function, which is capable of correcting for positioning such that zero points of an industrial robot and a workpiece coincide with each other, is capable of: simplifying a configuration of a workpiece support as compared to when movement of the work support holding the workpiece is controlled for correction to reduce size and cost of the workpiece machining device, and automating positioning work of making the zero points of the workpiece and the industrial robot coincide with each other to achieve labor-saving of work machining work. Three-dimensional machining data is calibrated based on displacement data in X-, Y-, and Z-axis directions computed by a comparison unit to make the zero points of the industrial robot and the workpiece. The industrial robot is then driven and controlled based on the calibrated three-dimensional machining data to perform machining for the workpiece.

Abstract: To provide work processing apparatus capable of positioning and stably supporting various types of works of different shapes and capable of performing processing effectively by supporting a work in an arbitrary posture. A work processing apparatus positions a reference support member to a center portion of a work, moves support members in directions in which they approach and separate from each other and an up-down direction in accordance with supporting portions of the work, and performs required processing by controlling movement of a work processing section in a state where the work is supported in a given posture by the reference support member and two support members.
