The Performance of Polycrystalline Diamond (PCD) Tools Machined by Abrasive Grinding and Electrical Discharge Grinding (EDG) in High-Speed Turning

In-Process Electrical Dressing of Metal-Bonded Diamond Grinding Wheels

A new development of hybrid in-process electrical dressing of metal-bonded diamond grinding wheels is proposed in this paper. The electrical dressing method is used for overcoming the limitations of the conventional dressing methods available in relation to a super-abrasive wheel because of the hardness of its abrasive grains and the durability of its bonding material. The proposed hybrid in-pr...

Micro Cutting Simulation of Abrasive Grains in the Grinding Process

In the current work we present approach to study the mechanism of the cutting of abrasive grains in the grinding wheel using finite element analysis (FEA). The simulation process is done by separating two abrasive grains from the grinding wheels and the microprocess of material removal in the case of surface grinding is simulated. Modelling was done on the workpiece steel S-7 and material grain...

Investigation of the Model of Microscopic Contact Parameters for Grinding M200 Using Elastic Abrasive Tool

In this study; utilizing the elastic matrix ball has higher processing efficiency and better superficial quality than traditionalgrinding. The diversity of elastic abrasive tool characteristics contact with bend surface results in irregular wear abrasion，and abrasive tool machining status gets complicated. There is no theoretical interpretation of parameters affecting the grinding accuracy. Bec...
