Laser Integrated Manufacturing – A benchmark

Abstract Efficient manufacturing of parts out of sheet metal is challenging for the industry and especially for prototypes and small to medium sized batches. This paper presents a benchmark comparing the most common industrial setups and the upcoming technique Laser Integrated Manufacturing (LIM). LIM represents a novel approach to modern manufacturing of parts made from sheet metal by integrating multiple laser-based processes into a single industrial manufacturing machine. This method eliminates the need for traditional tools and moulds while enabling seamless execution of cutting, forming, and welding as well as other laser processes within the same system. This integration eliminates the need for traditional tools and moulds, streamlining workflows, reducing production time, minimizing material handling, and enhancing precision. Additionally, the use of standard sheet metal and the ability to manufacture parts directly from CAD drawings, also contributing to cost savings and operational efficiency. This paper explores the achievements and technological advancements made possible through LIM in a benchmark, highlighting its impact on modern manufacturing. This benchmark shows that LIM is an effective manufacturing alternative compared to traditional manufacturing setups from prototypes to medium batch sized parts. But for large batch sizes fixed-tool stamping and punching are superior. Preliminary corrosion and fatigue tests indicate comparable or improved performance over traditional mechanical bending.
