Step S502, the wire electrode of the wire cutting machine tool is passed through out of the slips main body (1) centre bore；
Step S503, the institute that the slips main body (1) makes the wire electrode enter any slips monomer (11) side is adjusted
It states in cutting gap (14), and makes to form preset angle between the wire electrode and the axis of the slips main body (1)；
Step S504, another to the slips monomer (11) along the direction perpendicular to the wire electrode by the slips main body (1)
The cutting gap (14) of side translates, and carries out cutting to the slips monomer (11) by the wire electrode and forms cutting inclination
Face (12), and the range of the slips main body (1) is the described of the wire electrode and slips monomer (11) other side
The position of cutting gap (14) intersection；
Step S505, the position for adjusting the slips main body (1) makes the wire electrode enter slips monomer (11) other side
The cutting gap (14) in, and keep the wire electrode coplanar with the cutting inclined surface (12)；
Step S506, by the slips main body (1) along the institute of described cutting inclined surface (12) Xiang Suoshu slips monomer (11) side
Cutting gap (14) translation is stated, the cutting inclined surface (12) is made to form the complete interior tapered plane (13), and the slips
The range of main body (1) is the cutting gap (14) of cutting inclined surface (12) and slips monomer (11) side
Intersection position；
Step S507, step S503 to step S506 is repeated, the cutting until completing all slips monomers (11) is formed more
A slips monomer (11).
13. according to the method described in claim 8, it is characterized in that, insertion angle between the multiple block teeth (21) and embedding
It is identical to enter depth difference, and the top of the multiple block teeth (21) is arranged in concyclic cylinder.
14. according to the method described in claim 10, it is characterized in that, the slips main body (1) include eight cutting lines to
The slips main body (1) is divided into eight slips monomers (11).
15. according to the described in any item methods of claim 8 to 14, which is characterized in that the slips main body (1) is integrally formed
Structure.
