Abstract: A cutting apparatus includes a chuck table that holds a workpiece, a processing unit that forms a processed groove in the workpiece, an imaging unit that images the workpiece, a display unit that displays a captured image of a processed groove imaged by the imaging unit, and a control unit that executes display control of a display screen of the display unit. The control unit causes a mark that indicates the latest processed groove based on the Y-coordinate of the latest processed groove to be displayed on the display unit while being superimposed on a captured image.

Abstract: A restrictive control system for a differential which drives both drive axles at the same time but allows them to turn at different speeds during turning. The system variably generates a restrictive force, with which the differential is restricted in differential action, during turns. The restrictive force is reduced when a change in engine load is detected which is greater than a predetermined value and a steering angle is detected which is greater than a predetermined angle.
