During grinding, temperatures are generated as a consequence of the energy expended by the process. The use of coolants is the most common strategy to take the heat out of the contact zone. Irrespective of the type of the fluid used, there is a general trend to move towards dry process if possible. The reason for applying dry processes lies in cost reduction and legislation. Further issues arise in terms of health and environmental pollution. However, the desire to eliminate fluid usage in grinding processes represents a considerable challenge due to the high energy input and high heat flux generated within the grinding zone.The aim of this project is to develop a process strategy assuring the effectiveness of specific structuring in external cylindrical plunge grinding. These method is based on a new dressing method to create some special macro-structures on the wheel surface to increase the uncut chip thickness. It also aims to provide the optimized process conditions that can be directly applied in industry through a process-oriented approach. For this purpose, the mechanism of the interaction between wheel and workpiece during material removal process should be theoretically modeled and clearly understood in terms of technology.
