An Investigation on Orthogonal Machining of a Hybrid Polymer Composites Reinforced with Particulate Natural and Synthetic Fibres: A Soft Computing Approach

摘要

In first part of the study, thermal conductivity of the hybrid polymer composites at different % of particulate rice husk fibre and with a fixed % of particulate carbon fibre (5%) is studied by experimentation. Later, orthogonal machining test is conducted on the composites with composition for which thermal conductivity is minimum. To investigate the influence of machining parameters on surface roughness (Ra) and main cutting force (Pz), experiments are planned on the basis of central composite design of response surface methodology (RSM). Then ANOVA regression analysis is done for the experimental results of machining. It is found that speed is the predominant parameter that influences surface roughness and depth of cut is for main cutting force.
