Abstract

Abstract

SKD11 steel is a kind of special and difficult-to-cut materials used as key part of a military missile rack, which service surface needs to meet mirror roughness. Traditional grinding and polishing method is time-consuming and laborious due to the high hardness of SKD11 after quenching. For achieving high material removal rate to the workpiece surface, polishing tests on curved workpiece using elastic abrasive were carried out. The polishing model for curved surface polishing by elastic abrasive was established. The effects of the process parameters on the material removal rate(MRR) and abrasive wear were analyzed. A multi-index optimization based on MRR, abrasive wear and surface roughness(Ra) was realized by grey relation analysis and Taguchi method. The results showed that the setting cut depth and grinding speed are the main influencing factors of MRR and abrasive wear. To guarantee the life of the abrasive tool, the setting cut depth should be less than 0.3 mm and the grinding speed is below 9 000 r/min in polishing by elastic abrasive. The optimal parameter combination is the abrasive of #320, grinding speed of 3 000 r/min, setting cut depth of 0.3 mm and feed rate of 2 mm/min. The mean Ra of the workpiece achieves 0.056 μm and MRR increases 2.6 times with an improvement of abrasive wear under the optimized parameters.
