Systematical design of the grinding tool profile and the machining strategy can enhance the load capacity of the tooth root by improved sub-surface quality and tooth root radius. Thus, the tooth root durability increases. For the continuous generating grinding less knowledge about the influence of the variety of gear and grinding worm specific data as well as machining parameters on the tooth root sub-surface and ground gear profile is available. The main objective of this research work is the fundamental understanding of the material engagement during tooth root machining for continuous generating grinding. The investigations focus on the interactions of the geometrical gear- and grinding worm data, grinding worm specification and machining parameters on the one side and the residual stresses, changes of material structure and profile deviations on the other side. Experimental grinding operations, material removal simulations as well as analytical process observation will lead to the aimed main goal of this work.

磨削刀具轮廓和加工策略的系统设计可以通过改善次表面质量和齿根半径来增强齿根的承载能力。因此，齿根的耐久性提高。对于连续生成磨削，关于各种齿轮和磨削蜗杆具体数据以及加工参数对齿根次表面和磨削齿轮轮廓的影响的知识很少。这项研究工作的主要目标是从根本上了解连续展成磨削的齿根加工过程中的材料啮合。研究重点是一方面几何齿轮和蜗杆磨削数据、蜗杆磨削规格和加工参数之间的相互作用，另一方面关注残余应力、材料结构的变化和轮廓偏差。实验磨削操作、材料去除模拟以及分析过程观察将实现这项工作的主要目标。
