磁流变抛光技术研究进展

Research Progress of Magnetorheological Finishing

表面质量是精密零部件最重要的性能之一,零件的表面质量主要是由加工过程中不同的工艺参数和方法决定的。传统的磨抛工艺由于作用在工件上的力很大、嵌入的磨料颗粒、对工艺的控制有限等原因很难使表面粗糙度降低到精密零部件的要求精度。磁流变抛光(MRF)提供了一种新型高效的方法使工件加工质量达到预期的精度水平。MRF对工艺控制具有更大的灵活性,并且可以在不破坏表面形貌的情况下完成加工。综述了磁流变抛光液组分对加工效果的影响、材料去除模型的建立和发展、不同的MRF加工方式和未来磁流变抛光技术发展的新方向,最后总结了目前MRF技术存在的问题总结,并提出了MRF技术未来可能的发展方向。

Surface quality is one of the most important properties of the precision devices,the surface quality of parts is mainly de-termined by different process parameters and methods in the processing process.Due to high forces acting on the workpiece,the em-bedded abrasive particles,and the limited control of the process,the traditional polishing process is difficult to reduce the surface roughness to the required precision of precision components.Magnetorheological finishing(MRF)provides a new and efficient method to make the workpiece processing quality reach the expected accuracy level.MRF has greater flexibility for process control and can be processed without destroying the surface topography.This paper reviews the influence of magnetorheological polishing fluid components on the machining effect,the establishment and development of material removal models,different MRF process-ing methods and the new direction of future magnetorheological finishing technology development,and finally summarizes the current problems of MRF technology and puts forward It shows the possible future development direction of MRF technology.
