abstract

The quality and performance of products involving high precision and moving parts mainly depends on surface finish and dimensional accuracy. Generally, finishing operations use fine abrasive particles in different forms with some carrier or binding medium. Finishing operations are important, expensive, uncontrolled and labor-intensive in full production, and total production contributes significantly to time and cost. Surface finish requirement increases, the cost of finishing operation increases rapidly. Although, to some extent, progress has been made to automate finishing tasks to reduce production time, but the initial investment and operating costs are greatly increased, by selecting the optimum values ​​of process parameters, the quality, cost, time and efficiency of operation Much improvement can be done. In this paper, the details of the process parameters of two advanced fine-finishing processing have been presented, i.e. friction flow machining (AFM) and magnetic abrasive finishing (MAF), using nano-level using the real-coded genetic algorithm (GA) Are able to finish the surface. ). It also describes the development of a surface roughness model, which was developed to create objective functions for the optimization of the AFM process.
