“…The grinding characteristics can also be influenced to a considerable extent by the composition of the grinding wheel. Bifano [9] has demonstrated the general suitability of bronze bonding materials for ELID grinding, although the different types of bronze bond were not investigated in detail.…”

Electrochemical dressing of fine-grained metalbonded diamond grinding wheels enables to grind hard and brittle materials in the ductile mode. Optical surfaces can be manufactured by grinding, which reduces the need for subsequent, time-consuming polishing work. When using metal-bonded grinding wheels, the emerging oxides regulate the electrochemical dissolution. Bronze-bonded grinding wheels are more suitable for grinding cemented carbides and ceramics than iron-bonded grinding wheels, as it is easier to modify their chemical composition to suit a specific grinding task. They can also be sintered at lower temperatures, which reduces the risk of thermal damage to the diamond. In this paper, the dissolution and the oxidation of different bronze alloys are characterized for the electrochemical dressing process. The relevant evaluation criteria are the oxide layer thickness, the electrical behavior and the different emerging bronze alloy oxides

“…Ohmori (112) proposed a new method for electrolytic in-process dressing (BUD) of metal-bond wheels and discussed the application of this method for ceramic grinding. Bifano et al (113) and Welch et al (114) described the use of electrolytic in-process dressing for bronze-bond diamond wheels in fixed-load grinding operation on silicon carbide. They indicated that the rates of film growth, film wear, and diamond wear were the controlling factors in designing a successful EUD process.…”

Machining is the process of shaping materials into useful articles by removing the unwanted material. In traditional machining processes such as in cutting and grinding, the unwanted material is removed by mechanical means using a cutting tool. Since the tool makes contact with the workpiece and either the tool, the workpiece, or both are in motion, tribology (i.e., the study of rubbing or sliding) becomes an important issue. Tribology has a crucial and significant role as an enabling technology, since tool wear is a major problem in the production of reliable and cost-effective products. This paper reviews recently published articles related to the wear of cutting tools and grinding wheels. These papers are classified into such areas as the wear process, measurement of wear, reduction of wear through the use of different cutting tools and abrasive materials, strategies used to monitor wear during machining and grinding, and in-process control of machining to compensate for tool wear.

“…A first attempt to model the layer growth (and wear) using a resistor as electrical equivalent of the layer was done by Bifano et al (1999). With this law it is theoretically possible to predict both the wear of the wheel bonding and the growth of the passivation layer.…”

The electrical behaviour of the dressing process in ELID-grinding

During ELID-grinding, the metallic wheel is kept sharp through an electrolytic dressing process in which a layer is grown on top of the wheel's surface. The electrolysis process can be modelled electrically using the Helmholtz representation of a boundary layer. Measurements show that at the start of the (pre-)dressing the capacitance of the system is at its highest value, above 10 μF. After a while, it drops significantly to a level below 1 μF. This signifies a change in the metal-electrolyte interface and the grinding wheel is covered with a layer of (hydr-)oxides. The model is refined in two ways. Firstly, the capacitance between the two metallic electrodes is added. Secondly, the self-inductance of the power cables is included. With the proposed model it is possible to properly simulate the electrical behaviour of the growth of the layer. It also provides a fundamental insight into the electrolytic dressing process.
