Abstract:

Within conventional manufacturing processes, turning stands out as a crucial educational experience for engineering students. This machining method, executed on a lathe, goes beyond the creation of revolution surfaces; it provides students with a unique opportunity to delve into the intricate details of part manufacturing. In this educational context, students explore the direct influence of factors such as the chosen material, feed rate, cutting speed, and depth of cut on the surface finish of machined parts. Attention is given to dimensions and surface characteristics, precisely measured to ensure they meet specified dimensional tolerances. A key aspect of this educational process is the assessment of roundness, an essential parameter for the proper functioning of components like rotating shafts, bearing tracks, pistons, and cylinders. Roundness is not just presented as a mathematical metric within a circle; it emerges as a crucial concept in shaping engineers who are equipped to tackle real-world challenges.

Manufacturing engineering courses go beyond theory; they immerse students in the practice of machining and dimensional verification. In this educational environment, students not only learn to use tools and machines but also develop skills to assess the quality of machined parts. This comprehensive approach prepares future engineers to confidently face industry challenges with practical experience. To further enhance this educational experience, a dedicated station has been designed. Equipped with a centering lathe, support for a digital comparator gauge, and computer connectivity, this station allows students to perform operations mirroring a real industrial environment. This approach, aligned with the principles of Industry 4.0, not only enriches practical education but also underscores the importance of adapting to emerging technologies.
