The 15° main cavity machining is simpler and not much described. The processing of the flutes of blood 37° 30' is difficult, and is described below. It can be seen from the perspective view of the workpiece stereograph 2 that the dihedral angle M-AC-N needs to be obtained first. Pass D point as the vertical plane of AC, pay AC to point F, pay M and N faces to EF and DF respectively, and cross the top surface to DE. Make
