Abstract

tCylinder bores of automotive engines are ‘engineered’ surfaces that are processed using multi-stagehoning process to generate multiple layers of micro geometry for meeting the different functional require-ments of the piston assembly system. The final processed surfaces should comply with several surfacetopographic specifications that are relevant for the good tribological performance of the engine. Selectionof the process parameters in three stages of honing to obtain multiple surface topographic characteris-tics simultaneously within the specification tolerance is an important module of the process planningand is often posed as a challenging task for the process engineers. This paper presents a strategy bycombining the robust process design and gray-relational analysis to evolve the operating levels of hon-ing process parameters in rough, finish and plateau honing stages targeting to meet multiple surfacetopographic specifications on the final running surface of the cylinder bores. Honing experiments wereconducted in three stages namely rough, finish and plateau honing on cast iron cylinder liners by vary-ing four honing process parameters such as rotational speed, oscillatory speed, pressure and honingtime. Abbott–Firestone curve based functional parameters (Rk, Rpk, Rvk, Mr1and Mr2) coupled with meanroughness depth (Rz, DIN/ISO) and honing angle were measured and identified as the surface qualityperformance targets to be achieved. The experimental results have shown that the proposed approachis effective to generate cylinder liner surface that would simultaneously meet the explicit surface topo-graphic specifications currently practiced by the industry.
