Effects of electrolyte composition and temperature on precision finishing of spur gears by pulse electrochemical honing (PECH)

摘要

This paper presents the experimental findings to explore the effects of electrolyte in improving surface quality of gear teeth profile during precision finishing of spur gears by pulse electrochemical honing (PECH) process. Electrolyte composition and electrolyte temperature were used as input process parameter while percentage improvement on average and maximum surface roughness values (PIRa and PIRtm) was used as measure of process performances. The experimentation was carried out in an indigenously developed experimental setup for PECH. Optimum values of electrolyte composition and electrolyte temperature have been estimated using graphical analysis. Work-samples were analysed before and after the process using optical profilometer to visualise the improvement in surface finish of gear teeth profile. Key features of the developed PECH setup are also highlighted.
