S4: smooth bottom surface: the light plane was observed with an R0.8 fly. To ensure the accuracy of the bottom surface precision data, a knife is used for back chipping, the bottom surface is connected in the same direction, and the allowance of 0.1mm is kept on the side wall to prevent the vertical surface of the side wall from being damaged.
S5: processing a straight body groove on the back or the side: in a straight groove on the back or side, such as a water collecting block groove, a large fly cutter can be used for directly cutting the groove to be as thick as 0.1mm, and high-cutter particles are used for cleaning the groove according to the size of an R angle of the groove.
