摘要

工作目的:考虑到假体部件的运动学特性,提高其铣削效率。方法:理论研究是在数学分析的基础上,利用现代软件和计算设备进行计算机建模。采用PowerMILL凸轮系统对铣削轨迹进行统计处理。结果:在制造假体部件时,最佳的加工策略是“移位选择3D模型”和“移位选择3D模型”。这两种策略为最短的核心处理时间提供了最短的空闲时间。采用模型移位“3D模型选择”策略和移位“3D模型选择”策略时,机器加工时间比“3D模型选择”栅格策略减少2倍,比“3D模型选择”涡旋策略减少3倍。然而,应该注意的是,所有4项研究都是在相同的切削模式下进行的,这对于高速铣削来说并不典型。Vortex的“3D模型选择”在这些切割模式下是无效的,因为它是专门为高速铣削设计的。使用光栅“采样3D模型”也被证明是无效的,因为它是用于开放平面上的工作。科学的新颖性:提出了最有效的制造假体部件的铣削策略。实际意义:对铣削策略的使用提出了建议。关键词:铣削,策略,假体,空闲动作,模型,工艺流程,操作,机器时间。

NCREASING THE EFFICIENCY OF MILLING THE SURFACES OF ENDOPROTHESES
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.
