The analysis of material removal rate of WEDM miniature gears

Gear fabrication in wire electrical discharge machining (WEDM) plays an important role manufacturing industries. This paper describes the analysis and optimization of process parameters for spur gear on brass workpiece (10cmx15cmx6mm) material by EDM process. The experiments were performed using design experiment (DoE) approach removal rate (MRR) was analyzed response surface methodology technique. effect input i.e. pulse time, off time feed MRR has been investigated. geometry gears analysed Scanning Electron Microscopy (SEM). study found that 0.4 μs 60 pulse-off 6 mm/min provides improved rate. variance shows are significant SEM image exhibits capability WEDM to machined miniature with a uniform distribution regular-shaped craters defect-free flank surface.
