A Novel Rotating Wheel Magnetorheological Finishing Process for External Cylindrical Workpieces

The recent rise in the demand for high precision, close tolerances, and super surface finish quality of components and part assembly modules in the competitive manufacturing industrial environment for the enhanced working life and functional requirements of machines at a global level. A new rotating wheel based magnetorheological process is designed and developed to fine finish the external cylindrical surfaces of soft as well as hard materials. This method is based on the operating concept of the cylindrical grinding system, except that the hard bounded abrasive wheel is replaced with the electromagnet wheel which is capable of generating the regulated magnetic field in the developed process. Due to the generated magnetic field effect, the CIP's particles in the magnetorheological fluid stick-on the wheel and tightly hold the abrasive particles. The fine finishing operation is performed with the help of flexible brushes created by the magnetorheological fluid. A significant range of high precision external cylindrical surface applications can be found in automotive, manufacturing, aerospa
