This thesis contain the report of machining performance of tool coating when apply in machining process. The aim of this paperwork is to present flank wear characteristics of titanium carbide (TiC) as coated material on cemented carbide tool during machining a medium carbon steel (AISI 1045) material in dry turning. Machining performance is determined according to tool wear, tool life and surface finish that obtained. The nominal (starting) workpiece diameter is 50mm and the cutting speeds used are constant at 700 m/min with feed rate and depth of cut is 0.2mm/rev and 0.5mm, respectively. The cutting time is considered in this machining test to identifY the tool life. Single interval of cutting time has been setup at constant cutting speeds which is 0.5 min each. From that, the appropriate cutting parameters for each cutting tool will be identifY depending on tool wear and tool life. Tool wear that appeared is analyzed by flank wear as recommended in ISO 3685 (1993): Tool life testing with single point turning tools. From study, the rate of wear growth and wear mechanism at the end of tool life was investigated in detail using image analyzer. From the photographs of progressive wear, it has been observed that the time taken for the cutting edge of TiC coated carbide tools to initiate cracking and fracturing is longer when cutting at low speed than at high speed such as 700 m/min. The critical cutting speed influence the surface finish of work material. Tool variables, work material variables and setup variables are factor that affect surface roughness in rough turning.
