The cutting tool of 0059in is machined, the order of this spare parts is sizable the dimension at a piece of stamp, the modular accent that line of many 100 code Mr Raleigh began to be engaged in EDM 1978 is machined, established EDM Department company 1997. Original, this company concentrates main energy on advisory job, make Mr Raleigh can combine its major technology and look of a few craft thereby. As the development of the company, the manufacturing tool that it discovers a few clients to be used to treatment of EDM model antrum chooses by outside assist the factory is offerred. Today, in the business of this company, unripe industry Wu is occupied 65% , advisory business is occupied only 35% . Machine tool of EDM line cut undertakes machining as electrode with lead, and the figure that machine tool of treatment of EDM model antrum needs according to place undertakes machining to workpiece. Mr Raleigh says: "EDM model antrum machines a machine tool to have taller flexibility than machine tool of EDM line cut, because of its electrode can use any figure. High to treatment aspect ratio (of bore diameter and length than) the mould, the application of this kind of machine tool is very general. " in fact, use at producing the pattern of medical treatment product, if produce the pattern of medical treatment injector, occasionally its aspect ratio exceeds 5:1 even. The requirement that satisfies these applied domains is more difficult, the mould that needs because of its is very costly, also easily fragile crack. In addition, a lot of such mould uses hard steel of high strenth temper by dipping in water to make, the stress that this can add action to go up in cutting tool necessarily. EDM Department company uses software of 2D CNC process designing to develop a program before. Use this kind of method to put in a such problems: When the geometrical appearance of certain part, need comparatives triangular computation of the amount. And, this software also cannot get used to the change of 3D outline surface. Process designing personnel can make simple rough sketch through writing G code, add its in the program, but the time with this need very long expenditure, and agree with only very simple outline. Besides, this software does not support new generation machine tool, if Che Xi is compound,the machine tool is mixed 4 axes machining center. Accordingly, weaving to this kind of machine tool when the program, its only method is to write G code again, in order to support its advanced function. When the system of CNC process designing that decides when Mr Raleigh investment purchases to be a foundation with hypostatic model, he chose Esprit software, because it has process capability of Knowledgebase knowledge base. Knowledgebase knowledge base lets process designing personnel can procrastinate from inside the database put the machine program that establishs before, is not from 0 begin to found new operating sequence. Mr Raleigh says: "After drab process designing function implements automation, OK and managing more time. In the meantime, by skilled after be being optimized further to standardizing an operation with experienced process designing personnel, more be helpful for shortening further treatment is periodic. As the elapse of time, the process designing mission that this company had established a treatment to operate a database to handle its majority. Nextpage applies example to be able to explain how this software helps this company solve the treatment problem of injector mould among them, the finish machining diameter that makes its final is achieved 0.

0052in (1in=25.

4mm, similarly hereinafter) , its public errand is ＋ 0.

0002in/ - 0. The aspect ratio of this finished product is in 11:1~12:1Between. The dimension length of electrode itself is 0.

18in, accordingly it asks its aspect ratio exceeds 30:1 even(see a picture 2) . This company is in a Roku-Roku HC-435 establish the production on milling machine this kind of spare parts, its are whole the repetition inside size range of pipe bent locates precision is 0.

000019in. Graph diameter of 2 this electrode is 0.

0053in, length is 0.

1800in, its aspect ratio exceeds 30:1, the process capability of the imitate function of Esprit software and Knowledgebase knowledge base shortened treatment cycle Mr Raleigh of this spare parts begins to open SolidWorks hypostatic model to undertake process designing in Esprit software. Next, he according to them whether most agree with machine tool of machine tool of treatment of EDM model antrum, EDM line cut or basis machine treatment circumstance, this the characteristic of hypostatic model is divided into 3 file processing. The program will be united in wedlock together with hypostatic model automatically, have geometrical figure the organization, blend in each characteristics next in. Mr Raleigh examine and verify the characteristic that chooses by these programs, make necessary modification. Next, it is the operating sequence that appoints metallic cutting according to these characteristics. The general characteristic that Mr Raleigh and personnel of other process designing have for place of this company product developed treatment operating sequence, store these operating sequence in Knowledgebase knowledge base. When software encounters similar characteristic, aux will be able to uses these operating sequence automatically quite. Not only made sure all programs can make full use of machine tool and cutting tool, and managing still the process designing time that has similar characteristic part and treatment are periodic. Next, this company applies Esprit software imitate to machine operating sequence. Imitate limits includes whole spare parts, cutting tool and machine tool, make process designing personnel can each independent cutting course in process of examine and verify. Machine through be opposite workpiece and former the design of the mould undertakes comparative, process designing personnel still can examine " finished product " quality, magnify according to place simulative mould, decide whether it accords with design requirement of the client. The company embeds block commonly in the subprogram, make the size of the file maintains go up in the level that can run. Next, these subprograms union arrives in array, generally speaking, use these subprograms to be able to make 70 electrode inside an evening shift, need not operate personnel to share management. Contrast of this program photograph is simpler, because electrode matchs completely with the appearance of the product, reduced the complexity that the machine tool moves thereby. Process designing personnel still ties abstract position and cutting tool route together. Whenever, should pass when cutting tool only among them when some position, it indicates a point with respect to meeting set. Below such circumstances, if the job needs to stop, it can stop a dot to go up to be started afresh in this, can avoid the appearance of empty knife cutting thereby. Anyhow, company of EDM Department of new-style software help shortened process designing time, raised treatment to manufacture efficiency. Accordingly, this company can be complex spare parts process designing inside shorter time, make its are had establish actual simulative ability, reduced the wrong rate of process designing thereby, and be helpful for shorten of the machine tool debug setting time. Mr Raleigh says: "We optimize a machine tool to machine the ability of the operation, and store them in the database, they will apply quickly at designing the ability of the characteristic to shorten each to machine cycle, it is better to make sure its get through optimized processing technique use. Esprit software also makes his easier change and evaluation treatment operating sequence, make its become more practical, this is helpful for continueing to improve our process designing method. This is helpful for continueing to improve our process designing method.. CNC Milling
