Study On The Detection & Controling Of The LSWEDM Gap State Energy

Using low-speed wire electrical discharge machining (LSWEDM) is a new type of nontraditional machining and has been developing for a few decades. The field of technical application of a much wider, For LSWEDM, the discharge gap energer detect and control technology is a very important technology, which has a direct impact on the performance of the process of stability and processing quality. Under this research background, the present paper has carried on the research design to the LSWEDM Gap State energer detect and control system.Broken wires is the key to solve the problem in WEDM, and it has something to do with the distribution of the energy on the anode and cathode. On the basis, This text.. set up the mathematical model about energy distribution of the gap and the station of the gap.The control system consists of mathematical model,hardware and software.The control system hardware has designed the power simulation part, the electric current detection circuit , current-to-voltage converters circuit , the effective pulse-detecting circuit , the voltage detection circuit, the comparison circuit of voltage, the circuit of analog-to-digital and digital-to-analog, and the microcontroller AT89C51 system; introduced the ISA bus structure characteristics.The control system software has introduced the ISA bus structure characteristics.
