Enhancing blade durability in textile cutting through parametric geometry and pneumatic mechanisms

This study presents the design and development of a novel fabric cutting blade based on parametric curves to enhance durability and performance in textile manufacturing. Conventional cutting methods often suffer from frequent blade wear and reduced precision, especially in strap-cutting applications such as undergarment production. By applying mathematical modeling using ecliptic and quadratic parametric geometries, this research introduces optimized blade profiles with improved stress distribution and reduced fatigue failure. The cutting mechanism, driven by a pneumatic actuator and controlled via a PLC-based system, was designed to deliver efficient and repeatable cuts. Finite Element Analysis (FEA) was used to evaluate the mechanical behavior of the blades under various loading conditions, confirming their structural integrity and fatigue life. Prototypes were fabricated using precision laser cutting and tested in real-world settings. Results indicate a significant improvement in tool life and cutting quality, making this technology a promising solution for the textile industry.
