On Abrasive Flow Finishing of Straight
Bevel Gear
Anand Petare , Neelesh Kumar Jain , and I. A. Palani
Abstract Abrasive flow finishing (AFF) is a non-traditional nano-finishing process
for radiusing, polishing, surface stress reliving, geometry optimization and deburring. This paper reports on finishing of straight bevel gear by using AFF. Experimental setup of AFF and a special fixture for holding workpiece straight bevel gear
were developed. Finishing result produced by AFF is significantly influenced by two
process parameters, namely finishing duration and extrusion pressure. Eleven experiments for AFF of straight bevel gear were conducted in two phases by varying
extrusion pressure and finishing time using one factor at a time approach. The
outcome showed high improvement in maximum surface roughness and average
surface roughness of gear which will further improve their service life and operating performance. Surface morphology study of AFF finished straight bevel gears
revealed that their flank surfaces are free from cutter marks, burrs, nicks, microcracks, micro-chips, and micro-pits. Result produced establishes the feasibility AFF
for precision finishing of straight bevel gear.
