南華大學(xué)機(jī)械工程學(xué)院畢業(yè)設(shè)計（論文）ⅱAbstractWire electrical-discharge machining(wire-EDM)I is an adaptation of the basic EDM process,which can be used for cutting complex two-and three-dimensional shapes through electrically conducting materials. wire-EDM is most commonly used for the fabrication of press stamping dies, extrusion dies, powder composition dies, profile gages, and templates. Complicated cutouts can be made in difficult-to-machine metals without the need for high-cost grinding or expensive shaped EDM electrodes.Because the technology of wire electrical-discharge machining is the technology of mechatronics, and it is the integrate application of many subjects and professional knowledge , for example mechanism、electrician、electron、numerical control、auto control and computer application. My design subject is DK7732 numerical control electrical-discharge perforation molding machining tool. DK means numerical control machining tool. 77means wire electrical-discharge perforation molding machining tool. 32 means the width of tool’s worktable. The design contains collectivity distribution design, landscape orientation feed design, portrait feed design, circumgyrate worktable design. It still includes intension calculation of gear wheel, the checking of ball bearing pole and the calculation of axis gearing life-span. The controlling system part contains the circuit of step-by-step electromotor control and the circuit of pulse electrical source. This part is the most important part of numerical control electrical-discharge machining tool, and it is very hard for me. The design of step-by-step electromotor control includes hardware circuit design and software system design. It explains the enlarging of CMOS chip and the design of keyboard display interface. The circuit of pulse electrical source uses high and low voltage pulse electrical source. The circuit is composed by transistor and unattached elements, it exports high and low voltage pulse, which can apply with two electrical-discharge interval and improve productivity. Key words: Numerical control wire electrical-discharge machining, principle axis motion , step-by-step electromotor, pulse electrical source
