Experiences
During my final internship at the research laboratory of the Institut Pascal, which took place from April until today, I focused on rectifying the printing control algorithm. The previous algorithm had an error in the inverse geometric model, notably observable when moving away from the machine's center, given its pseudo-polar operation. Concurrently, I conducted a comprehensive audit of the system to analyze existing shortcomings and defects across all levels. This encompassed mechanical aspects such as geometric defects, inadequate mechanical linkages, and inappropriate mechanical properties such as inertia and mass. On the control side, I identified issues such as incremental control and information loss in display, necessitating the use of a post-processor to convert Cartesian coordinates to polar coordinates for machine comprehensibility. This internship has honed my skills in analysis and problem-solving within an applied research context.
Between June 2023 and September 2023, my objective at General Electric Healthcare was to convert an existing G-code into a machining program using Creo NC. I began by analyzing and extracting the cutting conditions and tool trajectories from the raw G-code. Utilizing appropriate Creo NC functions, I worked on creating tool trajectories while adhering to profile and machining mechanical constraints. Additionally, I addressed a machining defect related to obtaining oversized threads when tapping with a bottoming tap by adjusting the drilling diameter. Furthermore, I resolved issues related to the post-processor by identifying and rectifying errors in the generated G-code. Ultimately, I succeeded in achieving a easily modifiable machining program, with the defect and post-processor corrected, thereby enhancing efficiency and precision in machining operations at General Electric Healthcare.
During my internship as an assistant engineer at Avionav in July 2022, my objective was to design 3D parts using Solidworks based on existing components. I utilized partial scans of aircraft doors to approximate their shapes and create intersections with reference planes, resulting in polygonal curves. Determining the structure of the parts, including identifying symmetry, axes of revolution, and parameterization, was crucial. The designed parts primarily consisted of fastening elements for landing gear and linkage for connecting ailerons to the frame, as well as the ailerons themselves. This design process relied on reference planes and the use of sweep functions to achieve the necessary shapes and contours. The outcomes of my work included the requested parts, technical drawings, and the Bill of Materials (BOM).
During my initiation internship to enterprise world at Tunisie Télécom in July 2021, my main objective was to familiarize myself with the corporate world. I began by understanding the company hierarchy, learning who manages whom, and adhering to the discipline, including punctuality and adhering to entry and exit protocols. As an assistant to a technician, I supported various tasks, predominantly involving customer site visits for repairs on installations, or cable and fault checks at the telephone exchange center. Following my mentor's instructions closely, I adhered to protocols for conducting tests to ensure information transmission quality. Overall, this experience provided me with valuable insights into corporate structures and operations.
