PROCESSING APPARATUS

A processing apparatus includes a processing feed unit and a control unit. The processing feed unit moves a holding unit along guide rails between a processing zone, and an imaging zone in which a workpiece is imaged by a camera. The control unit includes a correction amount calculation section configured such that, after forming a cut groove in the workpiece, the cut groove is imaged by the camera, and correction values in a Y-axis direction or a correction angle for the chuck table are or is then calculated from Y-coordinates of two points apart from each other in a processing feed direction on the cut groove, whereby when carrying out processing feed of the chuck table in the imaging zone, the camera is corrected in position in the Y-direction based on the correction values or the chuck table is rotated by the correction angle.
