Case Study to Illustrate the Potential of Conformal Cooling Channels for Hot Stamping Dies Manufactured Using Hybrid Process of Laser Metal Deposition (LMD) and Milling
(MDPI, 2018-02)
Hot stamping dies include cooling channels to treat the formed sheet. The optimum cooling channels of dies and molds should adapt to the shape and surface of the dies, so that a homogeneous temperature distribution and ...
Analysis of the Influence of the Use of Cutting Fluid in Hybrid Processes of Machining and Laser Metal Deposition (LMD)
(MDPI, 2018-02)
Hybrid manufacturing processes that combine additive and machining operations are gaining relevance in modern industry thanks to the capability of building complex parts with minimal material and, many times, with process ...
Five-Axis Milling of Large Spiral Bevel Gears: Toolpath Definition, Finishing, and Shape Errors
(MDPI, 2018-05)
In this paper, a five-axis machining process is analyzed for large spiral-bevel gears, an interesting process for one-of-kind manufacturing. The work is focused on large sized spiral bevel gears manufacturing using universal ...
Tetraparametric assembly method for the simulation and optimizaction of bolt tightening sequences in ASME ring type joints
(2018-02-23)
En el sector del Oil&Gas, debido a la gran longitud que suelen tener las tuberías de los oleoductos y gasoductos submarinos, se hace necesario fabricar las tuberías en pequeños tramos para posteriormente unirlos mediante ...

(2018-12-14)
Due to the competition of funding among different sectors of the economy and society, Pavement Management Systems (PMS) have become necessary for road agencies to design more cost-effective and longer lasting pavements and ...
Research Trends in Pavement Management during the First Years of the 21st Century: A Bibliometric Analysis during the 2000–2013 Period
(MDPI, 2018-07)
A bibliometric analysis based on Scopus database was carried out to identify the global research trends related to pavement management area from 2000 to 2013, and to improve the understanding of the research topics in that ...
A new overhang constraint for topology optimization of self-supporting structures in additive manufacturing
(Springer, 2018-11)
This work falls within the scope of computer-aided optimal design, and aims to integrate the topology optimization procedures and recent additive manufacturing technologies (AM). The elimination of scaffold supports at the ...
Flexible Abrasive Tools for the Deburring and Finishing of Holes in Superalloys
(MDPI, 2018-12-06)
Many manufacturing sectors require high surface finishing. After machining operations such as milling or drilling, undesirable burrs or insufficient edge finishing may be generated. For decades, many finishing processes ...
