Correlation of the dynamic properties of the manufacturing process on metal-cutting machines and energy efficiency of the process

Abstract

Increase of the efficiency of machine processing is related with minimizing the reduced costs for manufacturing a batch of parts while ensuring their quality. The efficiency of the cutting process is determined by minimizing the intensity of tool wear while ensuring the required quality metrics of parts. Optimization consists in determining the cutting speed in which the path traversed by the tool to critical wear and (or) loss of quality of parts will be maximized at manufacturing with fixed regimes. As a rule, the minimization of conditions of the wear rate correspond to the best quality metrics of parts. In addition, this condition does not contradict the performance requirement because when the cutting speed increases, there is always a tendency to reduce forces. The ways to reduce the intensity of wear are knew, but the influence of the dynamic state of the system on wear and loss of quality is not considered. Therefore, the determination of the correlation the dynamic properties of the cutting process and its energy efficiency, as well as the determination of the modes set by the trajectories of the machine’s Executive elements, characterize the next stage of improving the cutting efficiency according to conditions of minimization of the work of forces on a given path. The results of research on this problem are presented in the article.
