Performance Analysis Combination of Nickel and Zinc Coated Single Point Cutting Tool in Turning Operation

Machining is the heart of any manufacturing industry. For any kind of material like macro to heavy machinery requires machining. Cutting tool requires machining process. Engineers and scientist are working to find out the best technique for increasing the efficiency of machining process. The cutting tool coating is a process for increasing the performance and productivity in machining process. This thesis work objective is to analyze the performance of single point cutting tool coated with metal (Nickel and Zinc) in the turning operation of aluminum. Single point cutting apparatus utilized for machining cylindrical shaped specimen of aluminum. Several kinds of tests like depth of cut, feed rates and cutting speed are taken place. The temperature of work piece- tool interface and surface roughness is measured and obtaining the results for MRR. These data helped in analyzing the effectiveness of cutting process. The tool used is HSS and are coated with nickel and zinc separately. Total 24 tests are completed and comes about are tabulated. The values attained to draw a graph between coated and uncoated cutting tools are finally concluded. The results obtained from turning operation by coated tools are compared with uncoated tool to draw a valid conclusion.
