In conjunction with mechanical joining processes. Mechanical processes play a key role for the realization of multi-material lightweight structures, which are essential regard to environmental protection. However, dissimilar high-strength materials is challenging due varying properties partners and their high flow stresses often limited ductility. Thus, evolution established as well development innovative highly productive technologies necessary. Requirements volatile production environment...
Abstract In the era of smart manufacturing, modern manufacturing systems face high demands for enhancing process performance and reducing machine downtime. Sensors data are essential successfully implementing data-driven approaches to guarantee robust reliable monitoring, tool conditioning, or quality assurance. However, accuracy such highly dependent on gathered sensor influenced by implemented acquisition processing methods. For this purpose, work proposes a lightweight ontology provide...
High-strength aluminum alloys have a great lightweight potential due to their high specific strength-to-weight ratio. However, industrial use of this material is limited the low formability at room temperature. In recent years, so-called hot forming quench (HFQ ® ) process has proven, be an effective method for manufacturing high-strength alloys. During deep drawing, cooling rate generates subsequent aging operation and thereby formation strength-increasing precipitations. As result,...
Minimizing tool wear is a crucial goal in metal forming to increase the durability and thus reduce costs. One approach superimpose movement with high frequency oscillation. The so-called ultrasonic assistance enables an immediate process force reduction lowers workpiece loads significantly. This phenomenon has been discovered by Langenecker Blaha 1955 since then confirmed for several applications like wire drawing, deep drawing forging. Nevertheless, underlying softening mechanisms are still...
Due to the rising demand for weight and volume reduction, usage of high strength materials becomes more common. Regarding process forces, application range existing presses is limited in forming such metals. One approach reduce forces considerably superimposing tool movement with ultrasonic vibration. Although immediate occurring force mean stress reduction were first discovered 1955 by Langenecker Blaha are known phenomena, underlying effects ultrasonic-based material softening remain...
Increasing material variety in car body engineering causes new challenges regarding the joining processes and therefore, leads to an enhanced usage of mechanical technologies. Mechanical fasteners, as self-piercing nuts, can be staked cost-efficiently without a pre-punching operation create detachable joints. Nevertheless, elevated workpiece strengths lead high forming forces limited application range. One promising approach reduce tool loads operations is superimposing high-frequency...
