Usage of waste carbide inserts in various machining operations and optimization of data by using taguchi methodology

The main objective of this research paper is to utilize the waste carbide inserts in various machining operations by developing the index able boring bars, index able milling cutters which can be used for utilization of waste carbide inserts. The turning insert having size CNMG 120408 is used. In industry this carbide insert is used for turning processes. This is negative insert having 80 degree angle and rhombus geometry. Four edges are used and after using its edges this insert become wastage. To utilize the other edges the special size of boring bar 25mm diameter for turning operation and 63mm diameter milling cutter for gangue milling is developed and used for machining in this research. To evaluate the effects of these special tools the taguchi methodology is used. The output results such as material removal rate and surface roughness is analyzed by taguchi methodology. Various materials are used to optimize and observe the results.
