Reduction of Die Wear and Structural Defects of Railway Screw Spike Heads Estimated by FEM
Autor: Jackeline Alcázar, Germán Abate, Nazareno Antunez, Alejandro Simoncelli, Antonio J. Sánchez Egea, Daniel Martinez Krahmer, Norberto López de Lacalle
Publikováno v: Metals, Vol 11, Iss 11, p 1834 (2021)
Railway spike screws are manufactured by hot forging on a massive scale, due to each kilometer of railway track needing 8600 spike screws. These components have a low market value, so the head must be formed in a single die stroke. The service life o

Abrasive Disc Performance in Dry-Cutting of Medium-Carbon Steel
Autor: Naiara Ortega, Vitaliy Martynenko, Daniela Perez, Daniel Martinez Krahmer, Luis Norberto López de Lacalle, Eneko Ukar
Publikováno v: Metals, Vol 10, Iss 4, p 538 (2020)
Abrasive-cutting processes are widely used to obtain semi-finished products from metal bars, slabs, or tubes. Thus, the abrasive cutting-off process is applied when requiring precision cutting and productivity at a moderate price. Cut-off tools are d
