Abstract
Machining of Co-Cr-Mo alloy is a challenging task for achieving a final machined surface integrity by identifying settings of input parameters precisely, which will be useful for manufacturing good quality implants. It is, therefore, important to understand the mechanism of machining mechanics using assessment of cutting forces. Even a minor change in the cutting forces generation may lead to problems related to tool wear, surface topography and surface integrity after the machining process. In this work, Response Surface Methodology (RSM) has been employed for modeling and analyzing machining parameters in order to obtain the machinability performance in terms of all cutting forces. All the experiments were carried out in a dry cutting environment with cBN insert by considering environmental care. Axial fore (F x) is not showing statistical significance, therefore, only radial force (F y) and tangential force (F z) were considered for further analysis. The depth of cut is having a statistically significant effect on F y and F z. Result shows that at higher range of input parameters (a p = 0.6 mm, f = 0.2 mm/ rev and V c = 200 m/min) the force magnitude increased up to 1019 N, 1282 N and 824.6 N for the axial (F x), radial (F y) and tangential (F z) components respectively. The higher forces generated shows increased roughness, R a value from 0.84 μm to 1.06 μm (20.75%).
