Analysis of Tribological Researches of Gear Cutting Processes of Cylindrical Gears in Real and Model Conditions

The availability, adaptability, reliability and productivity of modern industrial complexes, maintenance costs, energy costs and industrial production costs depend also on the intensity of wear of the elements of tribo-mechanical systems. Gear cutting operations are usually a bottleneck of production, especially in higher types of production. Therefore, the necessity of researching the process of gear cutting by hob milling is obvious. In the paper a part of the results related to the possibility of direct measurement of the temperature in a very complex process of gear cutting of cylindrical gears by hob milling is given.

Milling Tools

The improvement of the gear cutting process by hob milling is also significant for the producers of gears as well as for the producers of hob milling tools. Due to the complexity of the process, the high values of the gears, and in particular the hob milling tool, the research of the bases for optimizing the process of gear cutting by hob milling requires significant financial resources and significant efforts of the researchers. In the modern production of gears there is a continuous demand for increasing the economy. In the gear cutting process improvements of the production equipment and materials for the cutting elements of the hob milling tools are necessary. In this paper an analysis of the tool life of coated hob milling tools for gear cutting of cylindrical gears is given. The experimental results have shown that the hob milling tools with inserted combs coated with TiAlN outperform the hob milling tools with inserted combs coated with TiN. They have higher resistance of 60.6 %.

Mechanical Tool

Tools used in cutting processes with multi-flank chip formation like gear hobbing or bevel gear cutting, often reach their tool life due to excessive wear at the tool corner radius. Tool wear depends on the strength of the cutting edge and on the thermal and mechanical load. The objective of this work is to analyze the thermal and mechanical tool load during multi-flank chip formation. As the tool load cannot be measured in the necessary high local resolution, a finite element based machining simulation is used to model the process of chip formation. The simulation is able to calculate the temperature and stress distribution along the cutting edge. For the examinations presented in this report the bevel gear cutting process for ring gears is simulated. The simulation results show a significant thermal and mechanical load maximum at the tool corner, where the maximal wear occurs in cutting.
