บทคัดย่อ

Micro-channels have been used for introducing chemical reactions, mass transfer and/or heat exchanger in some functional micro-devices. Micro-milling process using a micro-tool to mechanically shear off a work material is normally employed to precisely cut the channel. Although a number of published studies have revealed some effects of micromachining parameters on cut dimensions and process performance, a very little discussion has been made on the cut surface quality and material removal rate in the machining of micro-channel. Hence, this study aims at investigating the effects of machining parameters on these two aspects. AISI 304 stainless steel was selected as a work material to be machined by a TiAlN-coated tungsten carbide end mill. A set of experiments was carried out where the workpiece was cut under the different feed rates and depths of cut. Channel width, depth, surface roughness, burr height and material removal rate were considered as the process responses in this study. A multi-objective optimization was also performed to determine a machining condition optimally balancing both the cut surface quality and material removal rate. The condition associated with the feed rate of 30 mm/min and cut depth of 2 μm was found to be a suitable one to promote the good quality of micro-channel and high machining rate. The findings presented in this study could widen the understanding of process behaviors and offer a guideline for process optimization. © 2019 The Authors. Published by Elsevier Ltd.
