A necessary condition for the successful development of the food industry is the improvement of technological equipment in order to increase the efficiency of raw material processing and reduce operating costs. Implementation of these requirements is particularly relevant in the meat processing industry. One of the main types of meat processing equipment are bowl cutters. Many researchers have worked on the research and improvement of these machines. However, despite the achieved scientific results, in modern models of bowl cutters the strength of knives is insufficient, which leads to a significant reduction in the economic benefit of the use of these machines. In our opinion, the problem of increasing the strength of knives should be considered comprehensively. That is: increasing the static strength of the knife, increasing its fatigue strength, as well as increasing its vibration strength. The paper presents the results of research performed both experimentally and by numerical simulation. The values of pressures acting on the knife`s edge during cutting were set. The vibration strength of knives was studied and it was concluded that it needs to be improved. The fatigue strength of the bowl cutterknives was investigated. Based on the obtained results, a new method of strengthening knives is proposed, which allows to increase fatigue strength by 2.5 times. New designs of knives with high static strength have also been developed.
