Abstract
This paper describes the approach and the resulting solution developed under the scope of a project-based learning course within the Federal University of Santa Catarina's Mechanical Engineering bachelor. This approach aims to develop and exercise the students' abilities in project design and enhance their view and understanding of the market expectations, and from real industries' demands. In this context, a group of undergraduates, under the supervision of an advisor professor, was responsible for the proposition of new solutions for a machining device capable of sanding surfaces inside cavities. The current machining process reported by autoclave manufacturers is an expensive, long and insalubrious process as autoclaves present a squared-section long duct, considerably narrow for manual labor. Furthermore, the material, stainless steel ASTM 316-Ti, presents challenges to the machining process due to its austenitic nature, impacting the thermal conductivity in a high heat generation process. In addition, the presence of titanium enables the formation of Ti-CN (titanium carbo-nitride) groups, which are abrasive and harder to machine. In terms of methodology, given the project challenge, the development started by determining the user's and the project requirements, the state-of-the-art of the presented machining configuration, patents and standards research, and similar products review, activities which comprise the planning, informational and conceptual development phases, respectively. After deciding the initial layout, the group was divided into project areas: structure, displacement, tool-to-piece contact, and machining, in order to perform the so-called preliminary and detailed phases of development. As result, aside some industries' interest in the resulting solution, from the learning perspective, the course presented a fertile and engaging environment for the application of technical knowledge acquired during the graduation course, such as project management, project methodology, solid mechanics, vibration, machining and machine elements.
