Abstract
The present investigation is based on micro-geometry of miniature spur gears manufactured by wire electrical discharge machining (WEDM). Effects of pulse-on time, pulse-off time and feed rate on surface roughness were analysed using response surface methodology and ANOVA analysis. The miniature gears have an outside diameter of 9.889 mm, face width 3.105 mm and nine miniature spur gears were fabricated. It was revealed from the observation that errors were seen during the fabrication of miniature spur gear at a high level of discharge energy. Scanning electron microscopy is also performed to analyse the geometry of the gears. This study found optimum surface roughness for miniature spur gear is 1.48 µs.
