摘要

The magnetic field-assisted finishing (MFAF) experimental process, using a medium of magnetorheological fluids (MRF), improves the surface quality. The response surface methodology Box-Behnken design (RSM-BBD) was used for this investigation. Consequently, the BBD model was chosen to optimize the input parameters, such as the polishing tool speed, surface finishing time, and gap between workpiece-too surface, which significantly influence the surface roughness. The author examined how these surfaces characteristics affect the input process parameters. The novelty lies in the MFAF finishing process for bio-zirconium alloys, which utilizes different toolpaths, parallel and spiral toolpaths for nano-level surface finishing. The surface roughness was reduced by 97.22% with the parallel toolpath pattern, 85.71% with the spiral toolpath pattern in the experiments, and 93.8% according to the predictions of the RSM-BBD design model. The Parallel toolpath method is better at creating very smooth surfaces using the MFAF process. It was perfect for making well-finished orthopedic devices while maintaining their durability and friction-related qualities.
