A Novel Magnetorheological Grinding Process for Finishing the Internal Cylindrical Surfaces
A novel magnetorheological grinding process is introduced to finish the inner cylindrical surface of the workpiece. In this approach, magnetorheological polishing fluid is used as a medium for the finishing of the inner cylindrical surface. The magnetorheological grinding tool helps to slash away the roughness peaks present on the workpiece surface. The simulation along with experimentation is performed to validate the effectiveness of the process. The input parameters such as current, tool reciprocation speed, tool, and workpiece rotation speed are considered for experimentation. The output parameter is observed in terms of change in surface roughness value from 250 to 110 nm in 60 min of finishing time. The roughness profiles and scanning electron microscope images proved the efficacy of the developed magnetorheological grinding process. This process can finish the internal cylindrical surfaces for industrial applications such as cylindrical molds, dies, hydraulic cylinders, etc.
