Abstract—Honing process is the final operation in manufacturing of connecting rods. The surface roughness, dimensional accuracy and the surface texture of the big and small eyes of the connecting rod are dependent to the honing process. In this research, the machinability of the PSA TU3 engine connecting rod is experimentally studied in terms of the effect of rotational and reciprocating speeds and well as the lubrication condition on the tool and work-piece temperature, surface roughness, honing oil consumption, honing tool wear and honing power. The design of experiments is carried out using the response surface central composite method. The results show that the lubrication of the honing tools can excel the machinability of the connecting rods. An optimization is also conducted on the results and the optimum input parameters are obtained. The optimized rotational and reciprocating speeds are also obtained, being 350 rpm and 11.7 m/min respectively.
