由于高效率和稳定的产品质量，CNC加工在现代加工业中占据主导地位。然而，传统加工对于某些生产环境仍然具有重要意义，例如原型制作和加工劳动力准备。CNC和传统加工需要特定的技能和知识，这些技能和知识可能是特定类型机床所独有的，也可能在一定程度上重叠。随着生产量需求的增加和劳动力的老龄化，需要有效地量化，保存和转移所述技能，以确保未来专业人员的有效准备和制造业的不间断运营。此外，在工业4.0中观察到的以人为本的制造系统的转变需要深入了解人在加工中的作用。本文提出了一种新的研究方法，该方法基于眼动跟踪和视频数据的收集和分析，辅以口头访谈、调查和自我评估。进行的案例研究涵盖了整个加工过程，从零件评估，切削策略确定，加工操作，到过程重新评估和优化。结果表明，更大的变化，在切割策略的操作顺序，操作的数量和连续的生产运行之间使用的生产工具，可以观察到传统的加工，在这些条款中指出的数控加工为基础的生产变化不大。总体而言，所收集的数据已允许获得深入了解机械师的决策过程和观察到的切削策略变化的基本原理，允许潜在的未来应用所提出的研究方法，在改善加工培训和潜在的援助过程设计，通过应用的研究结果进行与使用所提出的研究方法的专家系统和未来的CAM/CAE软件解决方案。
Due to the high efficiency and consistent product quality, CNC machining has gained a dominant role in the modern machining industry. However, conventional machining still has its significance for certain production settings, e.g. prototyping, and machining workforce preparation. CNC and conventional machining require particular skills and knowledge, which can be unique to specific types of machine tools or overlap to a certain extent. With increasing production volume demands and an aging workforce, a need for efficient quantification, preservation and transfer of said skillsets arises to ensure effective preparation of future professionals and the undisrupted operation of the manufacturing industry. Moreover, the observed shift towards human-centered manufacturing systems in the Industry 4.0 necessitates obtaining an in-depth understanding of human roles in machining. The following paper proposes a novel research approach based on collection and analysis of eye-tracking and video data supplemented by verbal interviews, surveys and self-assessment. A conducted case study spans the entirety of the machining process, from part evaluation, cutting strategy determination, machining operations, to process re-evaluation and optimization. The results show that far greater variability in cutting strategy in terms of operation order, number of operations and used production tooling between consecutive production runs can be observed for conventional machining, with little variation in those terms noted for CNC-based production. Overall, the collected data has allowed to gain an insight into the machinist's decision-making processes and the rationale for observed cutting strategy changes, allowing for potential future application of the proposed research method in improving the machining training and potentially aiding process design by applying the outcomes of studies performed with the use of presented research method to expert systems and future CAM/CAE software solutions.
