Research on the profile modification of power skiving tool for internal gears

The International Journal of Advanced Manufacturing Technology, 2021
Abstract Power skiving provides an effective solution and considerable machining efficiency for the machining of internal gears. The tool profile design and the reusability after resharpening is critical in gear machining. In this paper, a tool profile correction method based on the error inverse complement of involute profile is proposed.

General and comparative aspects of endometritis in domestic species: A review

Reproduction in Domestic Animals, Volume 58, Issue S2, Page 49-71, September 2023., 2023
Abstract Endometritis is a leading cause of sub‐ and infertility in domestic animal species. The healthy uterus is colonized by commensal bacteria, viruses and yeast/fungi that represent the nonpathogenic microbiota. A shift in the number or type of organisms accompanied by immune dysfunction, however, may trigger uterine infection and inflammation ...
