Research on Electrolytic Grinding of Slender Shaft with Variable Cross-section Based on ANSYS

In order to decrease bending deformation of slender shaft with variable cross-section in the process of electrolytic grinding, follow-up electrode of variable loads is used to support the workpiece, and software ANSYS is applied to analyze the typical low rigidity, slender shaft with variable cross-section in electrolytic grinding. The authors compare and analyze the deformation law and stress variations of the workpiece by using common follow-up electrode and follow-up electrode of variable loads. The follow-up electrode of variable loads diminishes the maximal bending deformation of the workpiece from 27.9 μm to 9.8 μm and the minimal one from 19.5 μm to 6.7 μm, which greatly reduces the deformation of the workpiece. Finally, the machining experiment results indicate that follow-up electrode of variable loads can decrease bending deformation of the workpiece, and raise the machining accuracy of the workpiece as well.
