Abstract

This paper presents the experimental investigation that will be done on the machining performance of coated and uncoated cutting tools. The workpiece materials selected in this project is ATST D2 high carbon steel. The coated cutting tools that will be used is TiC (titanium carbide) with the substrate of ceramic which is alumina (Ah03). The cutting tools will undergo machining tests by using CNC turning machine and then it will be analyze in order to study their performance. The selected coated cutting tools will be test af various cutting condition which involved 4 setting conditions. There w111 be only one parameters varied which is cutting speed. The feed and depth of cut will keep constant for all the setting conditions. At the above cutting condition, the performance characteristics measure includes the surface roughness value and surface texture. A surface roughness tester, scanning electron microscope (SEM) and optical microscope will be used to examine the surface integrity.
