In this article. the relevance of the study of gears with a complex non-involute profile of the tooth flanks is justified. For the subsequent study of non-involute gearings. the task of mathematical modeling of the profile of a gear-cutting rolling tool for machining of noninvolute gear wheels is solved. https://www.jmannino.com/hot-choice-Lions-Big-Chain-Necklace-mega-pick/
