About the Project
As part of a two-semester dual project, the design and development of an affordable 2D CNC plasma cutting system for small and medium-sized enterprises (SMEs) was undertaken in collaboration with INDAT GmbH. The goal was to create a standardized in-house product that extends existing hand-held plasma cutting tools with a CNC quick-assembly system. This solution offers a cost-effective alternative to conventional CNC systems, particularly for companies with limited production space. During the first semester, the focus was on project initiation, the development of the electrical engineering concept, and comprehensive market and feasibility analyses. In the second semester, the project progressed to the detailed
mechanical design of a folding axis system, which was subsequently validated through finite element analysis (FEA). The project consistently emphasized practical implementation and economic viability, laying the foundation for a scalable, industrial-grade product suitable for market introduction.

Technical Appropach
The technical implementation was carried out in two consecutive phases. In the first project phase, the focus was on developing the electrotechnical concept, conducting a risk analysis, defining specifications, and assessing economic feasibility. This phase was supported by structured development tools such as mind maps, flow charts, and the quality gates method. In the second phase, attention shifted to the mechanical design, which was carried out using Siemens NX11 and CATIA V5. A central innovation in this phase was the development of a folding mechanism for the axis system, allowing for space-efficient storage and transportation of the machine. Customer requirements were continuously integrated using an iterative "design thinking" approach. In addition, extensive finite element analyses (FEA) were performed on safety-critical components to verify their load-bearing capacity. As a result, a functional and economically viable solution was developed that meets both technical demands and market requirements.

Retrospective
The project was a complete success: within two consecutive semesters, a thoroughly designed concept with realistic market opportunities was developed from a product idea. The combination of electrotechnical planning and mechanical design made it possible to work through all core areas of product development. The close cooperation with the company INDAT GmbH not only promoted technical knowledge, but also methodical and social skills. The application of modern methods such as quality gates and design thinking in a real company environment proved to be particularly valuable. The challenges, such as the acquisition of CATIA V5 or the integration of customer feedback, were mastered in a targeted and efficient manner. The project represents well-founded project work and offers a practical, marketable solution.
