The use of 3 kinds of software in numerical control process designing (PRO E CIMATRON DELCAM)

Numerical control process designing has a lot of software, the most commonly used have software of PRO / E, the software such as UG, CATIA, CIMATRON, DELCAM. The mould that is in our country processes trade, it is a few kinds of software mix commonly use. Take benefit filling abuse. We cast the treatment company that mould factory is metallic mould and Die Casting mould. Use software of PRO / E to undertake designing now, use the function that actually body parameter changes. And software of numerical control process designing uses CIMATRON and DELCAM. The effect that uses in real work is better. One, the changeover of data format: IGES is the most general pattern, make mistake machine rate is less, although be changed into corresponding figure to have a mistake, also can revise. Do not affect the process designing quality of the mould. The file of PRO / E is changed into CIMATRON file, outside giving this kind of IGES to change a pattern, still have the changeover kind of a kind of neuter file, namely Neutral File, suffixal for NEU. The effect wants to be close friends than the format of IGES. The POWERMILL of numerical control module in DELCAM software can read the form of CIMATRON software directly, but the effect is not quite good, be had by the curved surface of clip one part by repair. The PX-EXCHANGE in software of best use DELCAM has transition, the effect is close friends some. Although use IGES to change a pattern, data changeover effect is the idealest. 2, when numerical control process designing, the method of another kind of corrective program: After to program is good, checking program can undertake with the means such as SIMULATOR and VERIFIER. Its effect still is possible usually. But in working actually, if install milling cutter cutting tool the mistake, two kinds of means cannot check above come out. When program of work out numerical control, as a result of all sorts of reasons, often set the diameter of milling cutter the fault, perhaps install the milling cutter of crop ball head milling cutter sometimes, namely cutting tool of actual milling cutter and cutting tool of program milling cutter are not accorded with. The cutting tool that resembles R5 is set into R6, the cutting tool of R6 is set into R5 to wait. To avoid afore-mentioned wrong happening. Through long research, summary. the cutting tool parameter in the program, be like the name of cutting tool, the diameter of cutting tool, the radius of point of a knife of crop milling cutter. The method that handles with postposition puts forward, put its in name of classics of cutting tool road. When calling a program, can consult. In FANUC system, still can be inside numerical control program with parameter of cutting tool of bracket form annotate, also can assure the validity of milling cutter parameter. For example the name of classics of cutting tool road that CIMATRON software makes is: 1002010-x2-sxh.

Caor3r0.

D6.

0-R0.

0.

Hei among them 1002010-x2-sxh is name of mould spare parts, Caor3r0 it is program name, among them radius of milling cutter of R 3 delegate, D6.

The 0 diameters that are cutting tool, R0.

The round horn of 0 point of a knife that are cutting tool, Hei is the abbreviate of system of Heidenhain of numerical control machine tool. 3, function of the editor after DELCAM software is better: Function of the editor after DELCAM software is opposite for it is better. Can cut down on aleatoric direction. Way of treatment of line of its racing bicycle is more pragmatic to a few vintage machine tool operating systems. Knife phenomenon jumps in treatment less, saved many auxiliary handling time. And the classics of cutting tool road that computation gives, can edit arbitrarily, need not repeat calculation again. Saved the computational time of work out program. 4, of method of a kind of clear root in CIMATRON again perfect: In means of CLEANUP clear root, will vertical section and horizontal area use different cutting tool treatment respectively. Move is as follows: 1, in horizontal area, the cutting tool that uses the part of arc of smooth fillet roundlet with larger radius undertakes machining. Stayed to use the raw area with same circular arc of cutting tool radius with place in vertical section. Use the OnLY VERT in REMACHIN.

CONS.

Z method is machined. If pursue 1. Most the cutting tool of underside passes A. Use cutting tool radius to be R10, horn of point of a knife is R32, in vertical section, the cutting tool that uses the part of arc of smooth fillet roundlet with minor radius perhaps uses the ball head cutting tool with lesser radius to undertake screw type is machined. Use the OnLY HOR Z in REMACHIN.

ON SRF.

Methodological treatment. If pursue 1. The cutting tool of upside passes B. Use cutting tool radius to be the ball head knife of R5. 3, in vertical section most below and horizontal area are handed in collect place have local area raw, have rudimental area. Use WCUT to machine this area only right now, height uses the height of horizontal area. Namely the treatment height of A of classics of cutting tool road. If pursue 1. Most the cutting tool of underside passes C. Use cutting tool radius to be the ball head knife of R5. This method suits spare parts appearance deeper, the stiffness that can assure cutting tool, intensity and spare parts machine quality. Graph 1- - of clear root method again perfect 5, an example in real work: Cast mould factory to be in treatment car apply the brake dish when the mould, pursue as follows 2. Use CIMATRON software, because crown is in R,be R3.

The crop milling cutter of R3 of 2 use radius should problem of it doesn't matter. But the person of use CIMATRON software knows, should machine sunken model when cutting tool dimension and sunken model differ very hour, the program does not move at all, perhaps move to also make mistake, pursue as follows 3: Formed different cutting tool method. If narrow cutting tool radius,arrive R2.

5 when, the effect of treatment is better, but the stiffness of cutting tool, intensity was reduced, the influence machines efficiency and quality. Then we convert DELCAM software. Change its DELCAM with IGES format, treatment parameter and CIMATRON are identical. If pursue 4. Will pursue 3 with the graph the cutting tool method of 4 undertakes comparative, it is good that the effect that sees DELCAM software treatment from the graph should compare CIMATRON software much, and the mould that treatment comes out has been compared really. The likelihood in real work encounters all sorts of problems, the respective dominant position that uses software is complementary, achieve treatment to give the goal of eligible product. Graph 2 apply the brake dish software of 3 CIMATRON of graph of mould top view machines apply the brake dish the example of the mould pursues 4 DELCAM software machines apply the brake dish the example of the mould is picked from " CAD/CAM and manufacturing industry informatization " 2003 first phase CNC Milling
