Selective adjustment of the specifications of the grinding worm can lead to a significant enhancement of the grinding tool performance and affect its tool life. Yet, it is so far not possible to forecast the influence of the porosity and grain size for different process conditions for the wear behavior and grinding-in period. One reason for this is the incomplete understanding of the influence of the interactions for continuous generating grinding with vitrified bonded CBN-worms. The main objective of this research work is to achieve a fundamental understanding of the interactions of the grinding worm specifications and the process parameters relating to value of the grinding-in period for continuous generating grinding. Furthermore, the influence of the thermo-mechanical load on the tooth flanks and the temperatures during grinding will be studied. Conducting specific experimental grinding operations as well as measuring the process temperatures will lead to the aimed main goal of this work.

选择性地调整磨削蜗杆的规格可以导致磨削工具性能的显著提高并影响其工具寿命。然而，目前还无法预测不同工艺条件下孔隙率和晶粒尺寸对磨损行为和磨合期的影响。其中一个原因是对陶瓷结合CBN蜗杆连续展成磨削的相互作用的影响的不完全理解。本研究工作的主要目的是实现一个基本的理解的相互作用的磨削蜗杆规格和工艺参数的价值的磨在连续展成磨削。此外，还将研究磨削过程中热机械载荷对齿面和温度的影响。进行特定的实验研磨操作以及测量过程温度将导致本工作的主要目标。
