An active/passive joint for reconfiguration applications
(Springer, 2019-09-07)
In this paper, an active/passive reconfigurable 2R joint is presented. Direct and inverse kinematic problems and the force transmission are considered. The advantages of the current design show its superiority with respect ...
Estrategias mecánicas de las plantas arborescentes: enseñanzas estructurales de los árboles
(Universidad de Tarapacá, 2017-09)
Los árboles son los seres vivos más grandes que jamás han poblado la Tierra, pudiendo tener más de cien metros de altura, masas de varios miles de toneladas y alcanzar edades de varios miles de años. Para conseguirlo, entre ...
A model-based sustainable productivity concept for the best decision-making in rough milling operations
(Elsevier, 2021)
[EN]There is a need in manufacturing as in machining of being more productive. However, at the same time, workshops are also urged for lesser energy waste in cutting operations. Specially, rough milling of impellers and ...
Study of the Environmental Implications of Using Metal Powder in Additive Manufacturing and Its Handling
(MDPI, 2020-02-17)
Additive Manufacturing, AM, is considered to be environmentally friendly when compared to conventional manufacturing processes. Most researchers focus on resource consumption when performing the corresponding Life Cycle ...
Predicted Torque Model in Low-Frequency-Assisted Boring (LFAB) Operations
(MDPI, 2021-06-24)
A low-frequency-assisted boring operation is a key cutting process in the aircraft manufacturing sector when drilling deep holes to avoid chip clogging based on chip breakage and, consequently, to reduce the temperature ...
Threading Performance of Different Coatings for High Speed Steel Tapping
(MDPI, 2020-05-10)
Threading holes using tapping tools is a widely used machining operation in the industry. This manufacturing process involves a great tool immersion in the part, which involves both friction and cutting. This makes the use ...
