[0002] The bottom plate of a table tennis racket is generally made of multiple layers of materials bonded together and cut into shape according to different needs. The traditional cutting process is that workers use a mold to hand-draw the outline on the surface of the board and then cut it. The hand-drawing process causes a certain deviation in the outline due to reasons such as the pen angle, and the hand-drawing efficiency of a large number of boards is low, and the workload is large. The cutting process will use a saw blade or a wire saw for cutting, and a large number of burrs will be generated on the edge of the board after cutting. In severe cases, defects will occur on the surface of the board, affecting product quality.
