Abstract
To fill the gap for the impact of electrochemical machining parameters on the electrochemical grinding process, solitary abrasive grinding was introduced to investigate the impact of electrochemical machining parameters on grinding material removal and abrasive wear during grinding. The results indicate that under identical grinding profundity, the grinding material removal volume after high-voltage electrochemical machining in the incipient grinding process was slightly higher than that after low-voltage electrochemical machining. In the subsequent grinding process, the abrasive granule materialize as macro-fractures after low-voltage electrochemical machining, causing the grinding material removal competence to diminish. After high-voltage electrochemical machining, the wear degree of the abrasive granule is alleviated, thereby persisting a higher grinding material removal competence. A grinding model was built to interpret the impact of electrochemical machining parameters on the grinding process. The study provides a theoretical guidance for the selection of electrochemical machining parameters for electrochemical grinding.
