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.

Abstract

This paper presents an experimental study on effect of micro drilling parameters on burr formation in C360 brass. Burr formation during machining is unacceptable in nature. Hence its dominant parameters are studied in this work. Micro drilling with 0.8mm HSS drill on C360 brass was performed. Response Surface Methodology (RSM) is used for design of experiments for the factors such as feed rate and spindle speed and experiments were carried out using multipurpose micro machine tool. Burr formation analysis was carried out using Scanning Electron Microscope (SEM) and inferences were made.
