Abstract

Hardened steel is often used in mould and die industry. Some of the application required to have mirror surface quality profile and sophisticated free form shape simultaneously. In current industry practice, polishing and grinding is often performed to achieve the required workpiece surface roughness which is generally performed manually by a skilled operator. Distinctly the existing techniques on achieving mirror surface finish for mould and die component have a tendency to lower productivity and difficulty ind ensuring the component accuracy. In addition, machining performances are affected by many factors such as workpiece and tool rigidity , cutting parameter, cutter path strategy and material characteristic. However, from all the factors that affect the machining performances, effects of workpiece and tool rigidity are often neglected. Therefore , this study will investigate the effects of workpiece and tool rigidity during the machining process, a rubber damper is place on workpiece and the cutting tool. Each proposed technique will be analyse and compare to evaluate its performance. Two types of material were used to investigate the effects of material characteristics on machining stabily in the experiment namely alumium alloys 6000 and AISI D2 tool steel.
