Abstract: Biomanufacturing integrates life science and engineering fundamentals to produce biocompatible products improving the pre-eminence of living. Face turning is an important process used for producing the higher accuracy on metal implants especially on sliding parts. In this experiment effect of depth of cut, feed rate and cutting speeds are considered on machined Co-Cr-Mo bio-implant alloy by application of RSM. The offline and online measured surface roughness (Ra) and cutting force (Fc) were considered respectively as response variables for investigations. The experimental result shows that depth of cut and feed rate are having predominating effect on measured surface roughness and cutting force respectively. Therefore, the developed models can be efficiently used to predict the surface roughness and cutting force on the machinability of  Co-Cr-Mo alloy within 95% confidence intervals ranges of measured parameters. For checking the adequacy of model a confirmation test has been conducted. The optimized parameters can be useful for industrial developments in surface generation for bio-implants.
