Abstract:
The manufacturing process for products with high degree of precision is very critical and hence increasing the surface
quality, wherever possible has been the prime motive, so many leading companies are working with high precision CNC-VMC
series for operations such as Drilling, Tapping, Turning, Milling, etc.
Surface roughness is the most important indicator of surface quality in machined items. So as to achieve that changing machine
parameters as per product size and environment is necessary. In this research, the parameters which are taken into account are :
spindle speed, feed rate, and depth of cut. Taguchi Design is utilized in this study to find the best combination of parameters to
reach out to the maximum surface finish criteria. For various combinations of three parameters: spindle speed, feed rate, and
depth of cut, experiments are carried out using the Taguchi orthogonal array. The surface roughness Ra is analyzed for each
experiment run using Taguchi.
