This thesis presents the effects of cutting fluid pressure towards various orifice nozzle sizes on the cutting performance. The cutting fluid is being used in metal cutting to optimize the process of machining operation. It has a significant role on shop floor productivity, tool life and quality of work. The objective of this study is to investigate the effects of various cutting fluid pressures on the machining of stainless steel AISI 304 and evaluate the influence of the cutting performance on machining parameters such as tool wear, tool life, chip formation and surface roughness on the process of metal cutting. Stainless steel AISI 304 and coated cemented carbide Ah 0 3 insert were used as a work piece material and cutting tool respectively. The experiments were carried out on CNC Lathe machine with 2 axes movements using various orifice nozzle sizes with cutting fluid type, synthetic soluble oils as a coolant. The acquired results showed that the coated cemented carbide Ah 03 insert gives the good overall performance in terms of tool life with the smallest orifice size. The cutting speed has great influence in the performance of coated cemented carbide insert. The tool life decreases with increases of the cutting speed. It can be seen that the maximum flank wear is the dominant failure mode when the orifice size increases during machining stainless steel AISI 304. This study can support the future exploration of dimensional accuracy, productivity and the cutting condition optimization.
