Abstract

This paperwork contains the report of the tool wear effect when machining different materials by using coated carbide tool. The materials used are mild steel and stainless steel. This The aim of this paperwork is to present the flank wear that occurred when machining mild steel and stainless steel using coated carbide tool with different parameter setting. Machining performance is determined by referring to flank wear obtained from the experiment. The machinery used in this experiment is conventional lathe machine. The material used for mild steel is mild steel with diameter 25 mm and for stainless steel is stainless steel with diameter 20 mm. The parameters varied are depth of cut, cutting speed and feed rate. The depth of cut is set to be 0.5 mm and 1.5 mm, with cutting speed 85 m/min. and 115 m/min, and feed rate 0.15 mm/rev. and 0.35 mm/rev. These variable are arranged according to the full factorial design. Wear that appeared on the cutting tool is measured with Sereo Zoom Microscope (SZM) and analyzed with Minitab software. From the result obtained, cutting speed and feed rate are the most significant factor that effect tool wear of the cutting tool.
