1, material of 　 of workpiece of machine tool of cut of numerical control electric spark and spare parts of work of semifinished product mould are used commonly forging semifinished product, treatment of its line cut often is in quench as junior as temper travel. Because suffer material oil to show sexual effect, mix when metal of large area purify when cutting off treatment, can make material interior leftover the relative balance position of stress is destroyed and generation is out of shape, the influence machines precision, create material in cut process even abrupt craze. To reduce this kind of effect, except should choose when the design forging good, temper by dipping in water shows performance quality good, heat treatment is out of shape little alloy tool steel (outside making mould material like Cr12, Cr12MoV, CrWMn) , forging to mould semifinished product reach heat treatment craft to also should undertake correctly. 2, the preparative working procedure of base of model of working procedure of modular base preparation is the full treatment working procedure before showing online cut machines punch or sunken model. (The makings below the 1) of 　 of preparative working procedure of 1) sunken model cuts off place to require data with sawing machine. 2) forgings improve in-house organization, and the form that forge wants into place. 3) anneal is eliminated forging internal stress, improvement machines function. 4) dig (mill) dig 6, leave grinding surplus 0.

4 ～ 0.

6mm. 5) is ground grind a fluctuation plane and photograph adjacent two flank, to angle square. 6) underlines contour line of lay off point and aperture (screw, sell the aperture, aperture that wear silk to wait) the position. Part of 7) treatment aperture is become when sunken standard is older, process a volume to reduce line cut, need will model mill of part of aperture leakage makings (car) piece, the stuff that; of cut point height shows a gender to differ to temper by dipping in water, but will model the partial data purify of aperture, leave surplus of cut of 3 ～ 5mm.

Screw of treatment of 8) aperture treatment, sell the aperture, aperture that wear silk to wait. 9) quenchs amount to design requirement. 10) grinds grinding fluctuation plane and photograph adjacent two flank, to angle square. 11) demagnetization handles 　 (the prepares working procedure punch preparation working procedure of 2) punch, but the structural characteristic according to punch, consult the preparative working procedure of sunken model, the working procedure take out that will not need among them can. But, should notice the following: 1) is facilitating treatment and outfit clip, cause semifinished product forge the parallelepiped commonly. Identical to dimension, appearance, the punch with section lesser dimension, can become moulding of a few protruding a semifinished product. Enough cut surplus should leave between the cut contour line of 2) punch and semifinished product flank (do not be less than 5mm) commonly. On semifinished product even put apart outfit places place. 3) falls in some circumstances, to prevent semifinished product of the model when cut generation is out of shape, want to machine an aperture that wear silk on modular base. Of cut introduce a program to begin from the aperture that wear silk. CNC Milling CNC Machining
