摘要: Abstract Silicon carbide (SiC) ceramics have been widely used in modern industry. However, the manufacture of SiC ceramic blanks is not an efficient process. The shaping with conventional machining methods (such as grinding) a long, labour-intensive and costly Wire electric discharge (WEDM) electrical (EDM) promise to be effective economical techniques for production tools parts from conducting that their resistivity below 100 Ω cm. these electrodischarge-machining large surface area on higher than 100 Ω cm shows low efficiency. This paper employs steel toothed wheel tool electrode machine specific 500 Ω cm using milling. process pulse generator EDM, uses water-based emulsion fluid. It able effectively 500 Ω cm. effects polarity, peak voltage, on-time, off-time, current performance investigated.
