Designing to be Built: Computer-Aided Design (CAD) with considerations for manufacturing and assembly processes

Computer-aided design (CAD) has revolutionized mechanical engineering design by aiding in the creation of detailed and precise components that were previously expensive and slow. Programs like SolidWorks allow engineers to visualize, simulate, and manufacture components effectively. However, CAD's impact extends beyond design; if correctly used, CAD can dramatically improve communication between engineers and fabricators, yielding significant cost savings and quality improvements. Optimizing components for manufacturing and assembly reduces production time, minimizes waste, and boosts efficiency. Overall, this project aimed to improve my CAD capabilities and understanding of common manufacturing practices. For my project, I adapted a wooden catapult designed by Leonardo De Vinci to be built using modern materials and manufacturing methods. The design was done in SolidWorks, and the primary manufacturing methods used were welding and CNC machining. Each step of the design and manufacturing process was explicitly chosen to highlight areas in which I lacked prior experience. This included designing a ratchet, welding aluminum with DC TIG welding, and implementing leaf springs and spring steel into a project.
