The purpose of this paper is to investigate the performance of two cutting oils, vegetable-based cutting fluid developed from palmolien oil and commercial type (semi-synthetic), for surface roughness during machining of SS202 austenitic stainless steel with coated carbide tool. Metalworking fluids (MWFs) acts as cooling and lubrication agent at the cutting zone in the machining process. There are now several types of metalworking fluids in the market but the mostly use water emulsion metalworking fluids. The use of mineral based cutting fluid in machining process induces negative effects especially on the environment, worker’s health and the machining cost itself. Metalworking fluids shown impact on tool wear, surface roughness, temperature and also other parameters.
