Cimatron is a software of outstanding CAD/ CAM that faces industry pattern manufacturing industry, provided whole modelling design, cartography, analysis and function of treatment process designing not only, and right model the whole production process of antrum mould, can offer a good solution. Cimatron is aimed at model the 3 axes milling with the most wide application in antrum mould treatment machines process designing, apply what its achieve formerly to be based on the technology of intelligent NC process designing of knowledge of semifinished product surplus, union machines all sorts of distinctive functions of mould spare parts, make its make one of solutions of CAM of model of current optimal antrum. The application of Cimatron of the following union in be machined actually introduces his to be opposite model the commonly used strategy of antrum model CNC Machining. The commonly used strategy of CNC Machining of model of 1 Cimatron antrum is in model milling of 3 axes numerical control machines antrum model spare parts in, handle to finishing from regular form semifinished product (basically point to polishing) the spare parts treatment before, treatment craft can divide its milling to process type of 4 kinds of working procedure for Ji Qinggen of rough machining, semifinishing machining, finish machining commonly. In the rough machining of semifinished product, although can be used,insert cut wait for other treatment form, but waiting for tall cutting still is the most commonly used form in be being machined actually. Cimatron offerred POCKET, ZCU T, WCU T 3 kinds of working procedure will support form of this kind of treatment. Because working procedure of ︱ ROU GH has WCU T to surround efficiently,cutting takes the advantage such as the feed setting that Dao Jizhi can change, have function of the treatment between distinctive layer at the same time, because this is working procedure of the most commonly used a rough machining. Of the semifinished product after ideal semifinishing machining should be based on rough machining leave incomplete to undertake knife course is calculated, cimatron has distinctive optimal beforehand to optimize a technology, working procedure of ︱ ROU GH of use WCU T, choose to machine the WITHSTOCK option in parameter, can make cutting tool contrail is generated according to the rudimental circumstance of the semifinished product after rough machining, not only comb-out empty knife phenomenon, and the cutting load of cutting tool is more reasonable, orbit is fluenter, optimize a technology to be able to build course of idealer semifinishing machining knife than using after the event. Through parameter is being machined between reasonable setting layer, the rework that can make the semifinished product between two cut remains to machine a face through the edge gets keeping clear of, compare with the methodological photograph that raise spare parts surface to machine precision through reducing a layer to fall highly, can fall in the premise that achieves same result, improve treatment efficiency greatly. Be aimed at spare parts finish machining, cimatron offerred working procedure of a lot of kinds of treatment to back different finish machining kind. If line of SURMILL (parameter is machined) , SURCLR(limitation line is machined) , SRFPKT(edge face is machined) , three-dimensional step pitch of 3D STEP (is machined) reach FIN2ISH(contour line of ︱ of WCU T to machine) etc, reach FINISH of ︱ of WCU T in order to be aimed at the SRFPKT of face of whole spare parts among them most commonly used. To whole treatment the face is told, using process of a kind of finish machining commonly always is endless and reasonable. Accept the even scale that is bordering on horizontal to slope, it is better to use SRFPKT working procedure to undertake edge face machines the effect, and receive the abrupt face that is bordering on vertical plane to use working procedure of FINISH of ︱ of WCU T to machine the effect commonly to slope idealer. Accordingly, need to undertake to machining a face slope is analysed above all, using proper form taking a knife respectively according to machining the different characteristic of the face next is most good treatment way. Use process of FINISH of ︱ of WCU T, choose BETWEEN LAYERS in machining parameter: HORIZ, can undertake to machining a face slope is analysed automatically, the area that differs according to analysing a result to be opposite uses different treatment form to undertake. Working procedure of root of local Qing Dynasty is crucial also to the treatment of the mould, besides can use REMACHINE: The round horn center that PENCIL is based on a model to go up undertakes Chan Biqing outside the root, use REMACHINE:CL EANUP can be based on circumstance of semifinished product surplus to undertake much talk move back and forth root of automatic Qing Dynasty, in order to achieve cutting tool cutting the purpose with smooth, even load. Use this process, can use area slope automatically to analyse algorithm to make cent manage somewhere else to area of abrupt peace calm, produce corresponding cutting tool method. Model if the commonly used strategy of antrum model CNC Machining expresses 1 to show. The treatment parameter setting of spare parts of model of 2 Cimatron model antrum is typical model antrum model spare parts is handsome core, model antrum and the electrode that electric spark treatment needs. It is especially in each working procedure in rough machining working procedure, should the different characteristic according to the spare parts, set different treatment parameter, in order to achieve ideal treatment result. Main introduction is aimed at the typical parameter setting of rough machining of of all kinds spare parts under. 2.

1 antrum kind the treatment of the spare parts to general model antrum kind the rough machining of the spare parts, can use process of ROU GH of ︱ of WCU T. According to the characteristic of this kind of spare parts, following set can make in machining parameter to express: (1) walks along knife means parameter to be set commonly for SPIRAL CU T, make cutting tool is made around treatment face surround cutting. (The type parameter of 2) treatment model installs commonly for OPENPART: NO, be in with demarcate feed of less than of size range of pipe bent. If the spare parts is interior existence and model the islands with antrum underside different height, if the graph is shown 1 times, should install for OPEN + ISLAND, the feed outside introducing semifinished product with parting in different cut or interior beforehand aperture is in feed. (3) feed parameter uses AU TO ENTRYPOINTS(commonly automatic feed dot) , get when need beforehand when aperture is nodded, can set optimize feed dot for OPTIMIZED ENTRY PNT () , cooperate to install CREATE ENTRY PNT: YES, in order to arise less beforehand hole site, if pursue,1 is shown. (General setting of RAMP AN GL E of parameter of 4) feed angle is 5 ° ～ 10 ° , in order to use corkscrewed yarn feed, cutting order parameter at the same time the setting is INSIDE OU T, in order to facilitate of corkscrewed yarn generate. Can adjust helix radius when necessary through parameter of reset MAX RAMP RADIUS. (5) to deeper model antrum treatment, if use the cutting tool of existence treatment blind area (if enchase the annular knife of hard alloy razor blade) the phenomenon that put aside a knife may appear when be down cutting. Subtract through be setting of MIN PLUN GESIZE cutting tool diameter double of round horn radius, can prevent to cut the area with too small size range of pipe bent, in order to avoid the risk that the possibility produces. 2.

2 model core kind the treatment rough machining of the spare parts, use process of ROU GH of ︱ of WCU T likewise. (1) walks along knife means parameter to be able to be set for STOCK SPIRAL, make cutting tool is made around semifinished product surround cutting, in order to improve the cutting efficiency of semifinished product. Graph the contrail of 2 rough machining cutting tool that after using SPIRAL CU T and STOCK SPIRAL parameter to part, differ to what same part generates. (The type parameter of 2) treatment model is installed commonly for OPENPART:OU TER ONL Y, can make sure cutting tool is outside the spare parts so feed. Cutting order parameter is installed commonly for OU TSIDE IN, general setting of RAMP AN GL E of feed angle parameter is 90 ° . (3) feed parameter is installed commonly nod for automatic feed of AU TO ENTRYPOINTS() . If pay no attention to,think, DE2FINE ENTRY POINTS(of optional choose defines feed to nod oneself) . 2.

The machines electrode rough machining of 3 electrode is installed basically with model core is identical. Different point basically is in finish machining. Commonly model of direct basis antrum gets electrode model, when report is machined, ask however electrode and model clearance of a discharge exists between antrum. Because electrode model may be formed by a lot of curved surface, if do much curved surface directly on the model,slant buy can have certain difficulty. To compensate discharge clearance, need what measure certainly through machining a face to cut implementation too. Implementation machines what the face measures certainly to be cut too have a variety of methods, if lesser cutting tool is used when computation, when be being machined actually, use a bit bigger of cutting tool " the law that cheat a knife " etc. But the most commonly used method is the SRF in be being expressed to finish machining parameter.

OFFSET parameter installs the negative worth with an absolute value and discharge equal clearance. Using cutting tool of requirement of this kind of method must be ball knife or round horn knife, and round horn radius is more than this value. Additional, different face may need what the setting differs to cut an amount too. The face that this can have differred to cut a demand through will having is defined respectively reach 2 (PART2SURF) of group of spare parts face for 1 (PART SURF) of group of spare parts face, install slant differently buy value will come true. 3 application case 3.

The treatment hook forging die of 1 hook forging die antrum is typical HAL F pattern, model antrum fluctuation is symmetrical, the three-dimensional and hypostatic model of lower mould is shown 3 times like the graph. The attrib border dimension of semifinished product is 60 Mm of × of 240 Mm of × of 240 Mm, fluctuation plane and all around outline already finish machining. Need to finish fixed position on machining center now Kong Ji is whole model the treatment of antrum, generated treatment process is as follows: (1) rough machining divides a working procedure to have extraction antrum contour line by deepness, use ConTOURROU GH + FINISH of POCKET ︱ , cutting tool uses a diameter to be the flat bottom milling cutter of Ø12 Mm, treatment depth range 0 ～ - 1.

50 Mm, the rest of parts use the thick precision work that completes flash chamfer with the form taking a knife of SPIRALCU T ConTOUR ROU GH of ︱ of WCU T, cutting tool still is the flat bottom milling cutter of diametical Ø12 Mm, treatment depth range - 1.

Minpz of 50 Mm ～ , undertake with the form taking a knife of SPIRAL CU T model of antrum wait for tall rough machining. Because make the same score bottom milling cutter to cannot be machined model the partial curved surface with antrum flatter bottom, because this need uses ball knife,be opposite model antrum undertakes rough machining 2 times. (Semifinishing machining uses 2) ConTOUR ROU GH of ︱ of WCU T, cutting tool uses a diameter to be the ball head milling cutter of <10 Mm. Treatment parameter chooses SPI2RAL CU T, WITH STOCK, BETWEEN LAYERS:ON SRF, the rudimental surplus of treatment antrum bottom. (3) finish machining uses ConTOUR FINISH of ︱ of WCU T, cutting tool uses a diameter to be the ball head milling cutter of <6 Mm. Treatment depth range - 1.

50mm ～ Minpz, treatment parameter chooses SPIRAL CU T, BE2TWEEN LAYERS: HORIZ. Use the divisional region that is based on automatic slope to analyse a result to machine, abrupt face is used wait for tall treatment, flat surface uses edge face annulus to cut have precision work. (Treatment of 4) clear root uses CL EANUP of REMACHIN ︱ , use a diameter to be the ball head milling cutter of <4 Mm. Treatment parameter chooses PREV.

TOOL=BALL6, SPL IT HORZ VERT, the clear root that basically is used at place of hook protruding ear and cleared other are local curvature radius is lesser the remain of place. After be being machined via afore-mentioned working procedure, if the graph is shown 4 times,the treatment of hook forging die emulates a result. 3.

The electrode model of the antrum of model of electrode treatment key-press of model of key-press of 2 copycat face plate is shown 5 times like the graph, the attrib border dimension of semifinished product is 85 Mm of × of 100 Mm × 35 Mm, fluctuation plane and all around outline already finish machining, treatment depth range is 0 ～ - 15 Mm. Need to finish fixed position on machining center now Kong Ji is whole model the treatment of antrum, generated treatment process is as follows (1) rough machining divides a working procedure to undertake use process of ConTOUR ROU GH of ︱ of WCU T by deepness, use a diameter to be the flat bottom milling cutter of Ø10 Mm, treatment depth range 0 ～ - 15mm, the key-press of purify of form taking a knife with STOCK SPIRAL group the semifinished product surplus all round. Working procedure of ︱ ConTOUR ROU GH of use WCU T, use the flat bottom milling cutter of diametical Ø4 Mm, treatment depth range is Alexandrine, choose WITH STOCK, on purify one working procedure does not have the semifinished product surplus between the key-press of purify. (2) semifinishing machining because surplus of the semifinished product after rough machining is evener, can use ConTOUR FINISH of ︱ of WCU T to undertake semifinishing machining directly, use the ball head milling cutter of diametical Ø4 Mm. Parameter of the treatment between the layer chooses BETWEEN LAYERS: HORIZ, PARALL EL CU T, use automatic and divisional region to machine, electrode flank is used wait for tall treatment, fluctuation surface uses cutting of edge face level to have precision work. Treatment face chooses all model side, SRF OFFSET = 0, electrode surface is cut to model dimension. (3) finish machining discharges for complement clearance, need is right different electric polar has undertaken cutting. Working procedure of ︱ ConTOUR FINISH of use WCU T, cutting tool still is the ball head milling cutter of diametical 4 Mm. Go up through be being reached to the flank of electrode on the model the color with exterior different setting, BY CRITERIA option is used in the course that defines spare parts area in this working procedure next, the side that chooses all electrode is PART SRF, fluctuation surface is PART 2 SRF. Install SRF respectively next.

OFFSET =- 0.

15, PART2 SRF.

OFST = - 0.

08, make electrode surface is formed different cut an amount too. Treatment parameter chooses BETWEENLAYERS: HORIZ, PARALL EL CU T. The expensive precision work such as electrode lateral knife course is shown 6 times like the graph, the course of knife of cutting of edge face parallel of the surface on electrode is shown 7 times like the graph. All after afore-mentioned working procedure are finished, if the graph is shown 8 times,the treatment of electrode emulates a result. Two afore-mentioned case, used Cimat Ron basically to be aimed at model the treatment of antrum mould spare parts is politic, very ideal result was obtained in be machined actually. In the meantime, discover not hard also from inside afore-mentioned case, have the characteristic according to specific treatment object only, to machining strategy medium individual working procedure undertakes proper adjustment, set appropriate parameter, ability makes machine already efficient can assure quality again.
