Title: SHOT PROCESSING APPARATUS AND SHOT PROCESSING METHOD
Abstract:
In shot processing in which a workpiece is pinched by a clamping device, the occurrence of unprocessed points on the workpiece is prevented. A shot processing apparatus according to the present invention that performs shot processing by projecting a projection material onto a workpiece comprises a clamping device that detachably pinches the workpiece, a projector that projects the projection material onto the workpiece pinched by the clamping device, a movement mechanism that moves the workpiece and the clamping device relative to each other, and a control device that controls the operation of the movement mechanism. The control device operates the movement mechanism in such a manner that the clamping device pinches the workpiece using at least two pinching positions that do not overlap each other.
