Study of optimised process parameters in turning operation through Force Dynamometer on CNC Machine

In this study we investigated the optimization of machining parameters for turning operation of given work piece, the material being Carburized Mild Steel (hard material), Aluminium alloys and Brass (soft material) which were machined on CNC machine and analysed through the cutting force dynamometer. Dynamometer being very effective equipment for the measurement of cutting force and turning tool used is made up of tungsten carbide for cutting metal. Our work is reduce of cutting forces and increase cutting speed by using force dynamometer for optimizing the process parameter and finding the better surface finish of given work piece material in turning operation. In this study we used different spindle speed, feed rate and depth of cut for both types (Hard & Soft) of materials, including tool geometry in machining operation on CNC, after successful experimentation the sample work piece is better surface finished by turning operation on CNC m/c due to optimum process parameters. As per our work enhanced surface quality i.e. surface finish & uniformity is found. This may result in reducing the cost of manufacturing in machining on high end/advanced computer controlled CNC.
