Abstract

Surface roughness plays an important role in product quality and how a real object will interact with its environment. The surface profile and roughness of a machined workpiece are two most important product quality characteristics for most mechanical products. The aim of this research is to find the significant parameters of turning process that affect the surface roughness. The model is developed in terms of cutting speed (CS), feed rate, and depth of cut (DoC). In this research, Precision Lathe Machine (MOMAC SPA) Model SM 200x1500 has been used to machine sample part (AISI 1040 carbon steel). For measurement, SJ-301 Surface Roughness Tester (Stylus Profilometer) will be used to determine surface roughness based on three factors that have been prescribed. Surface integrity and tool wear were analyzed using Metallurgical Microscope. Design of Experiment (DoE) will be used in order to study the relationship between these variables on surface roughness. The data will be analyzed using MINITAB 15 software. The result shows that cutting speed was the most significant factor that had affected the surface roughness (Ra) of medium carbon steel (AISI 1040).
