Abstract

In modern day of manufacturing, micromachining plays a key function in machining of new developed harder materials, which is an alternate machining procedure for many processes in industrial scenario. The core objective of this current effort is to progress a micromachining setup and to examine effects of micromachining parameters, for which an open source small Arduino CNC machine was developed for performing the micro-milling operation on a natural fibre (banana) and rice bran particles reinforced polymer matrix composite material with fiber resin combination of 1:3. By using Taguchi method experiments combinations were formulated considering speed, feed and depth of cut and the outputs of MRR and surface roughness were investigated using TOPSIS methodology for identifying the optimal parametric conditions. Analysis of variance is employed for identifying the most significant parameter and a validation experiment was performed with the identified optimum conditions.
