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.

在研磨过程中，由于该过程消耗的能量而产生温度。使用冷却剂是将热量从接触区带走的最常见策略。无论使用的流体类型如何，如果可能的话，总的趋势是朝着干法发展。应用干法的原因在于降低成本和立法。在健康和环境污染方面出现了进一步的问题。然而，在磨削过程中，由于高能量输入和磨削区域内产生的高热通量，消除流体使用的愿望是一个相当大的挑战。本项目的目的是开发一种工艺策略，确保外圆切入磨削中特定结构的有效性。该方法是基于一种新的修整方法，在砂轮表面形成一些特殊的宏观结构，以增加未切屑的厚度。它还旨在通过面向过程的方法提供可直接应用于工业的优化工艺条件。为此，在材料去除过程中砂轮和工件之间的相互作用的机制，应在理论上建模，并在技术上清楚地了解。
