Стаття присвячена аналізу різних методів нарізання зубчастих коліс дисковими фрезами з метою визначення їх переваг та недоліків щодо гнучкості, продуктивності та якості обробки. Крім того, в статті наведена класифікація стратегій обробки, які лежать в основі вищезгаданих методів зубообробки і були ідентифіковані шляхом їх аналізу. Purpose. Classification of different machining strategies underlying the known methods for gear cutting with disc-shaped milling tools as well as preliminary determination of their advantages and disadvantages before profound studies by simulations and experiments. Design/methodology/approach. This paper is concerned with the analysis of the different methods for gear cutting with disc-shaped milling tools in order to determine their advantages or disadvantages in terms of flexibility, productivity and machining quality as well as to make a classification of the machining strategies underlying these methods. Findings. By analyzing the gear cutting methods, it was found that they differ in strategies for material removal, tool movement and tool engagement. These strategies define advantages or disadvantages of the machining methods as well as their optimal application areas. Further, it was shown that some of the gear cutting methods are based on similar or even the same machining strategies. Originality/value. The results of the analysis show that none of the known methods for gear cutting with disc-shaped milling tools is universally applicable. Some of them provide a higher productivity and flexibility, and the others – a better machining quality. It means that, in order to select a perfectly suitable machining method with the optimal process parameters for each individual manufacturing task and thereby to increase the efficiency of the gear manufacturing, the profound knowledge about achievable productivity, flexibility and quality parameters are required. The proposed classification of the machining strategies underlying the gear cutting methods creates a basis for further theoretical and experimental studies of the mentioned parameters. Статья посвящена анализу различных методов нарезания зубчатых колёс дисковыми фрезами с целью определения их преимуществ и недостатков относительно гибкости, производительности и качества обработки. Кроме того, в статье приведена классификации стратегий обработки, которые лежат в основе вышеупомянутых методов и были идентифицированы в ходе их анализа. |
