In today’s rapidly evolving product development landscape, the efficiency and effectiveness of making a product heavily depend on the seamless integration of design and manufacturing processes. The progression of a design concept from development to manufacturing is often impeded by deviations arising during the manufacturing process and the subsequent repercussions they entail. While minor changes made during the initial stages of design have limited consequences, the necessity for significant manufacturing modifications later in the development cycle incurs substantial time and financial costs. To mitigate these challenges, it becomes critical to prioritize manufacturing validation as an integral component of the design evaluation process in all through its evolution, rather than as an afterthought once the design has been finalized. However, this endeavor is not without its complexities, given the intricate nature of designs. This thesis delves into the critical aspect of design validation for manufacturing, collaborating closely with the NXPS department of Scania to address their specific challenges due to manufacturing in EATS development. The prevailing method currently employed for evaluating the manufacturability of CAD designs heavily relies on supplier feedback or experiential knowledge garnered over years of experience as a mechanical engineer. While undoubtedly valuable, this approach often fails to keep pace with planned development cycles, resulting in frequent deviations. Moreover, beyond mere assessment, a thorough comprehension of manufacturing processes is essential for validating various functions of a design, ensuring alignment with real-world expected capabilities of the product. Thus, the central focus of this thesis lies in devising a method to address these shortcomings and contribute to optimizing the transition from design to manufacturing. Given the dynamic nature of manufacturing processes, this thesis centre’s its attention on sheet metal manufacturing, a primary process in manufacturing EATS. Through the utilization of real-world case studies, a two-step methodology is developed, intending to seamlessly integrate with the current SDD approach in EATS development. The initial step involves the utilization of Autoform for analyzing design manufacturability, while the subsequent step capitalizes on this knowledge to enhance structural analysis, thereby enabling more realistic stress assessments. By concentrating on sheet metal manufacturing and implementing a comprehensive two-step approach, this thesis proposes a tangible solution to comprehend the challenges associated with manufacturing deviations, thereby aiding decision-making processes in selecting more feasible and manufacturable design alternatives. / Autoform, CAD, CAE, CATIA V5, DataMapping, Manufacturability, Optimization, Parametric CAD models, Sheet Metal Manufacturing, Simulation Driven Design
