Abstract
When cutting a groove of a predetermined contour through a plate shaped workpiece with a fret saw blade, various program data regarding the direction of movements of the fret saw blade and the contour of the groove to be cut are stored in a memory device. The fret saw blade is moved in a direction instructed by the memory device and the orientation of the saw blade is controlled at the starting point of each segment of the groove.
