- Abstract
Thin-walled iron parts are easily deformed by traditional mechanical processing methods due to the poor rigidity. Besides, it is well known that the cutting tools suffer serious wear when machining pure iron materials. In this paper, a series of experiments were carried out to explore the performance of electrochemical grinding (ECG) method on machining pure iron material. The electrochemical characteristics of pure iron in the three common electrolytes were analyzed to provide a theoretical basis for selecting ECG electrolyte. A mathematical model based on finite element method was established to study the ECG process. Afterwards, ECG experiments, as well as conventional grinding (CG), with different processing parameter conditions were conducted. The results showed that the electrochemical characteristics could be highly predictive for the performance of ECG in different electrolytes. Besides, compared with CG, although the surface roughness after ECG increased, the grinding force was greatly reduced, and the material removal rate (MRR) was improved under recommended processing parameters. Furthermore, no plastic deformation layer, or hardening layer could be observed in the subsurface of ECG machined workpiece, indicating a uniform structure and non-residual stress in subsurface.
