Manufacturing of high quality miniature gears by wire electric discharge machining

---

This chapter presents the manufacturing of high quality miniature spur gears of brass by Wire Electric Discharge Machining (WEDM). Effects of four WEDM parameters i.e. voltage, pulse-on time, pulse-off time and wire feed rate on five responses namely profile error, pitch error, average roughness, maximum roughness and material removal rate are studied. The experimental research was accomplished in three stages namely pilot, main and confirmation experimentation. The bracketed range of WEDM parameters by pilot experimentation were used in the main experiments designed using Box-Behnken approach of response surface methodology (RSM) and finally the confirmation experiments were conducted to validate the optimum results predicted by desirability anaylsis. The miniature gears manufactured by WEDM had defect-free microstructure, very thin recast layer, good surface finish and having gear quality upto DIN standard 5 for micro-geometry parameters (i.e. profile and pitch) which is much superior than the quality of the miniature gears manufactured by other existing conventional processes.

Key words: WEDM, miniature gears, profile, pitch, RSM
