Optimizing Machining Parameters Using Carbide Insert for Rough Mild Steel Surfaces

摘要

In present day world importance of manufacturing plays a vital role in a industrialized nation. Metal cutting process involved in removing material from the workpiece. In this operation are classified based on position of cutting edge of the cutting tool. It can be either orthogonal else oblique cutting. Another important parameter is surface roughness and used as the measure of quality and productivity of machine tool. Serviceability of machine and tool significantly affected by the surface characteristics. In this work, various input parameters such as cutting speed and feed rate etc. are used while turning of mild steel with carbide tool. Optimum surface roughness identified using Taguchi method during turning. ANOVA is used to analysis cutting parameters. It was observed that more and more rough surfaces obtained with feed rate increment whereas less rough surface were obtained as cutting speed increases. Surface roughness highly affected by the cutting speed.
