Abstract The current study presents a novel Tailored Forming process chain developed for the production of hybrid bearing bushings. In first step, semi-finished products in form locally reinforced hollow profiles were produced using new co-extrusion process. For this purpose, modular tool concept was which steel tube made case-hardening steel, either C15 (AISI 1015) or 20MnCr5 5120), is fed lat...

Since the early 1930s, the process of melting glass and subsequently forming fibers, in particular discontinuous fiber glass or continuous glass filaments, evolved into commercial-scale manufacturing. Most commonly, a direct melt process is applied. Thereby, the several raw materials were mixed, fed into a furnace, melted and forwarded to the fiber-forming units. Here, the filaments are formed ...

Thermal friction estimations are presently essential on steel for manufacturing applications as they predict the aggregated energy required process. However, current thermal estimates inaccurate exclude optimized thresholds of both input and output quantities. In this article, optimization drilling operation process is accounted by introducing a new method combined Taguchi-Pareto–grey wolf-desi...
