In the present work, machinability study of stainless steel 316L in the microturning process by using multi coated tungsten carbide tool in a multipurpose micromachine tool is reported. Experiments are carried out as per design of experiments approach using L9 orthogonal array (OA). The input machining parameters varied are speed, feed and depth of cut. Machinability studies are conducted by measuring flank wear (VBmax) after 10th minute. In order to select the significant microturning machining parameters analysis of variance (ANOVA) and response graph are used. The results indicated that medium speed and low depth of cut are significant for lesser flank wear. The result obtained from this study is expected to be useful for micro components manufacturer to select the appropriate input machining parameters in microturning of stainless steel, which is used in various applications.
