Influence of the grinding tool specifications and process parameters on the wear behavior and grinding-in period of vitrified bonded CBN-worms for continuous generating grinding

有选择地调整磨削蜗杆的规格可以显著提高磨削刀具的性能，并影响其刀具寿命。然而，到目前为止，还不可能预测不同工艺条件下的孔隙率和晶粒度对磨损行为和磨合时间的影响。其中一个原因是对陶瓷结合型CBN蜗杆连续生成磨削的相互作用的影响认识不足。这项研究工作的主要目的是从根本上了解磨削蜗杆规格与与连续展成磨削的磨合周期值有关的工艺参数之间的相互作用。此外，还将研究热机械载荷对齿面的影响以及磨削过程中的温度。进行具体的实验研磨操作以及测量工艺温度将导致这项工作的主要目标。

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.
