Abstract: A control device comprises a first interface, a second interface, a processor, and a third interface. A first interface is configured to acquire a captured image of an article. A second interface is configured to transmit and receive data to and from an input/output device. A processor is configured to cause the input/output device to display an article image based on the captured image, receive an input of a position and an angle of a grip portion model of a grip portion that grips the article from the input/output device through the second interface, display the grip portion model on the article image, and generate a gripping plan. A third interface configured to transmit the gripping plan to a control unit of a gripping device including the grip portion.

Abstract: Disclosed are improved apparatus and method for effecting a required machining on workpieces with working liquid flushing to the tool-and-workpiece contacting place. Gas such as air is ejected to the tool-and-workpiece contacting place, thereby making the working liquid to forcedly invade into the tool-and-workpiece interface. Thus, cooling effect is enhanced to maximum while saving the quantity of working liquid, still assuring that the products of comparable or even higher quality are provided.
