STUDY OF CUTTING PARAMETERS DURING TURNING OF MMC (STEEL) USING RSM
This paper presents the influence of process parameters like cutting speed, feed and depth of cut on surface roughness (Ra) in turning MMC (metal matrix composites) using uncoated tungsten carbide insert under dry environment. The experiments have been conducted based on RSM. Abrasion and adhesion are observed to be the principal wear mechanism from images of tool tip. No premature tool failure by chipping and fracturing was observed and machining was steady using carbide insert. Built-up-edge formation is noticed at low and higher cutting speed and at high feed combination and consequently surface quality affected adversely. The optimal parametric combinations for surface roughness are used according to manually. Mathematical models for surface roughness are found to be statistically significant. Keywords: SURFACE ROUGHNESS, RSM, ANOVA, TURNING OPERATION, MMC
