This paper presents an experimental study on effect of micro end milling process parameters on surface roughness with PMMA (Poly methyl methacrylate) as work piece material. It has wide applications in micro features and micro parts fabrication for automobile, aerospace, biomedical industries. Effect on surface finish during micro end milling on PMMA with 0.7mm carbide end mill tool was analyzed in this work. Response Surface Methodology (RSM) technique used for design of experiments for the factors feed rate and spindle speed. Experiments were carried out using multipurpose micro machine tool. Analysis was carried out with surface roughness value measured using surface roughness tester and inferences were made.

Abstract


This paper presents an experimental study on effect of micro end milling process parameters on surface roughness with PMMA (Poly methyl methacrylate) as work piece material. It has wide applications in micro features and micro parts fabrication for automobile, aerospace, biomedical industries. Effect on surface finish during micro end milling on PMMA with 0.7mm carbide end mill tool was analyzed in this work. Response Surface Methodology (RSM) technique used for design of experiments for the factors feed rate and spindle speed. Experiments were carried out using multipurpose micro machine tool. Analysis was carried out with surface roughness value measured using surface roughness tester and inferences were made.
