Some investigations on surface roughness and cutting force in face turning of biocompatible Co-Cr-Mo alloy

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.

Surface properties and biocompatibility studies on bone plate by magnetorheological finishing

“…All experiments are performed at a room temperature of 25°C. The body fluid comprises protein, ions, water, and dissolved oxygen, providing an adverse environment for the biomaterials and triggering the corrosion rate [26]. Because of mechanical and chemical degradation, releasing metallic ions inside the human body results in metal allergy, carcinogenicity, genotoxicity, and cytotoxicity [27].…”

Mathematical Modeling Using ANN Based on k-fold Cross Validation Approach and MOAHA Multi-Objective Optimization Algorithm During Turning of Polyoxymethylene POM-C

“…The impact of interactions and cutting speed 𝑉 𝑐 was found to be negligible. Jagtap et al [23] delved into the effect of turning parameters on the surface flatness of both nylon and polypropylene. Their findings highlighted that the feed is the most influential factor for flatness in both polymers.…”

“…Man-made materials known as biomaterials have the ability to perform the functions of human bodily tissues [1]. Biomaterials play a major role in treating patients by replacing or restoring the function of failing tissues or organs in medical devices like pacemakers and biosensors, as well as implants like vascular grafts, artificial hearts, heart valves, intraocular lenses, dental implants, and bone plates.…”

“…Jagtap et al investigated face turning in a dry cutting environment with a CBN insert and cutting settings of V c = 100-125-150 m/min, a p = 0.1-0.2-0.3 mm, and f = 0.1-0.15-0.2 mm/rev [2][3][4][5][6][7][8]. Turning experiments were performed on AZ91HP magnesium alloy by Tönsoff et al [9].…”
