Abstract
Purpose to work: is to increase the efficiency of milling endoprosthesis components, taking into account their kinematic characteristics. Methodology: theoretical research was carried out on the basis of mathematical analysis, computer modeling using modern software and computing equipment. The PowerMILL CAM system was used for statistical processing of milling trajectories. Results: when manufacturing endoprosthesis components, the best processing strategies were "Selection of 3D model by model shift" and "Selection of 3D model by shift". These two strategies give the lowest idle time for the lowest core processing time. Machine processing time when using the strategies "3D model selection" by model shift and "3D model selection" by shift is reduced by 2 times compared to the "3D model selection" raster strategy, and by 3 times compared to the "3D model selection" strategy Vortex. However, it should be noted that all 4 studies were conducted at the same cutting modes, which are not typical for high-speed milling. Vortex's "3D Model Selection" is ineffective in these cutting modes due to the fact that it is designed exclusively for high-speed milling. "Sampling a 3D model" with a raster also turned out to be ineffective due to the fact that it is intended for work on open planes. Scientific novelty: the most effective milling strategy for the manufacture of endoprosthesis components is proposed. Practical significance: recommendations for the use of milling strategies are given. Key words: milling, strategy, endoprosthesis, idle movements, model, technological process, operation, machine time.
