Wire cutting processing technique of allotype male die

The invention discloses linear cutting processing technology for an irregular male die, which comprises the following steps: (1) processing the male die reserved with an intersection point by slow wire processing technology; (2) cutting out a groove of which the shape and size are completely consistent with at least half of the male die through linear cutting on a knife edge plate; (3) inserting the male die into the groove, and arranging the part of the male die reserved with the intersection point out of the groove; and (4) finishing and cutting the intersection point by the slow wire processing technology. Because the technology inserts the male die into the groove of the knife edge plate, of which the shape and size are completely consistent with the half of the male die, the technology precisely finishes and cuts the intersection point of the male die by the slow wire processing technology.
