【正文】 of machine tools is essential. (3) adaptive processing parameters, etc. can make a difference. The latest artificial intelligence technology into the development of WEDM, the development of highspeed wire cutting away parts of the intelligent control and enforcement agencies, which is the current national development priorities are consistent with hightech industry, has important practical significance. 電火花線切割 技術(shù) 摘要：隨著機(jī)械制造業(yè)水平的不斷提高和產(chǎn)品加工精度的需要，先進(jìn)的機(jī)械制造技術(shù)的應(yīng)用也就順理成章。 slow walk for a continuous thread cutting oneway wire, always kept in the processing area Sijia new electrode), high precision (5) relies on a tiny putercontrolled electrode wire traces and space pensation, while both concave and convex mold processing, the gap can be adjusted. (6) by emulsion liquid or to the working fluid from the water, do not have to worry about fire, day and night, no one can be a continuous process. (7) cutting WEDM can be difficult to machine or can not be the traditional method for processing high hardness, high strength, high brittleness, highRen Xing and other conductive materials and semiconductor materials. (8) at the beginning of any plex parts, as long as the preparation of processing can be processed, and thus very suitable for small batch production of parts and test products, processing, short processing cycle, application flexibility. (9) with four simultaneous axes, can be processed, the following specialshaped body, the shape distortion of the body surface, such as variable taper and spherical parts. (10) process, the tools are not in direct contact with the workpiece, there is no significant cutting force, enabling processing of lowrigidity workpiece. (11) and EDM as pared to the wire electrode instead of forming the electrode, eliminating the molding tool design and manufacturing costs electrode Used to shorten the production lead time. WEDM the disadvantage of low productivity, and can not be blind hole machining parts and ladder surfaces. applications: (1) The trial of new products: new product development process requires a single piece samples, use of wire cutting parts cut out directly, without molds, which can greatly shorten the development cycle of new products and reduce trial costs. Such as stamping, the die is not expected to open Chula, first with a wire cutting for forming such a model for subsequent processing, be verified before blanking die manufacturing. (2) processing of special materials: cutting some of the high hardness, high melting point metal, the use of machine processing methods is almost impossible, and economical use of line cutting can ensure accuracy. (3) processing mold parts: mainly used in EDM wire cutting dies, extrusion dies, plastic dies, EDM electrodes cavity mold processing, the EDM wire cutting speed and accuracy of the rapid increase has reached can pete with the coordinates of the degree of grinding. For example, the small die, the material is tool steel, in the past with a separate mold and method of curve grinding machining, EDM wire cutting now switch to the overall processing methods, manufacturing cycle can be shortened 3 / 4 to 5 / 4, reduce the cost of 2 / 3 / 4, with high precision, the work does not require skilled operators. Therefore, some industrial countries such as precision grinding washed process has been EDM and WEDM replaced. application areas: WEDM is mainly used for a variety of dies, plastic molds, powder metallurgy molds posed of twodimensional and threedimensional ruled surface of the mold and parts. Can cut a variety of templates, mags, silicon steel, semiconductor materials or precious metals, but also for micromachining, shaped slot and the standard specimen processing defects. Widely used in electronic equipment, precision machine tools, light industrial, military and so on. (1) plane shape of the metal mold processing: die, powder metallurgy mold, drawing die, extrusion die machining (2) threedimensional shape of the metal mold processing: Die by the withdrawal of the die groove machining, plastic with metal dies, plastic mold separation surface processing (3) EDM: production of plex shapes using microelectrodes the electrode process, the general processing of perforated electrode, the electrode process with taper mold (4) test products and parts processing: prototype parts directly to processing, batch processing of small variety of parts, special materials, spare parts processing, materials, processing of specimens (5) profile gauge processing: measuring a variety of card board processing, the cam and the template processing, shap
