One of the interests in machining is to attain better surface roughness with dimensional accuracy. Polymer composites has been continuously dispatching the conventional materials. Polymer based composites have superior mechanical strength and stiffness such as strength-to-weight ratio, high stiffness-to-weight ratio. Polymer composites are the one which are produced closer to the required shape and further machining is often necessary to achieve the expected surface characteristics. This study targets the machining of hybrid polymer, made in the form of round rod, using general purpose resin and cashew nut shell liquid with varying proportions of CSNL by volume fraction up to 30%. Machining is carried out and the study includes the influence of the various process parameters such as cutting speed and feed with depth of cut kept constant and their importance in deciding the surface roughness. Surface roughness was measured after machining under specified measuring conditions using Talysurf.
