Modernizing Machine Elements Design - A comparative study between theoretical frameworks and modern CAD software

Abstract

This bachelor thesis investigates the relationship between traditional theoretical frameworks and modern computer-aided design (CAD) software in the context of machine element design. As engineering workflows increasingly adopt automated digital tools, it becomes essential to evaluate whether these technologies uphold the transparency, educational value of manual calculations, and result validations. The study conducts a comparative analysis of selected machine elements using both manual calculations and various CAD platforms, assessing their performance based on precision, usability, and result traceability. A key aspect of the software investigation is the recognition that different CAD platforms are influenced by varying standards and theoretical foundations, often shaped by their regional or institutional origins. Although the industry strive to create common approaches and methods, many dif ferences remain. The findings highlight discrepancies in calculation transparency, underscore the importance of foundational engineering knowledge, and offer guid ance for effectively integrating CAD tools into academic use as well as professional practice. By bridging theoretical and digital methodologies, this research contributes to a more informed and balanced approach to modern mechanical design.
