Abstract:
Tool wear is a major concern in machining as it determines the tool life, the quality of the
machined surface and its dimensional accuracy, consequently, the economics of cutting
operations. Therefore, this project was conducted to study the tool wear behaviour in turning of
T6061 Aluminium alloy using Silicon Coated Carbide (SiC) tool at the presence of conventional
coolant and dry machining. For this project, the turning process was conducted using two depths
of cut, 1.0 mm and 2.0 mm, two different cutting speeds, 1570m/min and 1963m/min with and
without the application of conventional coolant as cutting fluid. For each setup of different
factors, the flank wear and surface roughness value were recorded. The results showed that tool
wear and surface roughness were significantly influenced by the different depth of cut, cutting
speed and machining condition.
