Intelligent nozzle design for the Laser Metal Deposition process in the Industry 4.0
(Elsevier, 2017)
Laser Metal Deposition (LMD) is an AM (Additive Manufacturing) process that enables to build 3D geometries or enhance the surface properties of the base material by the generation of a coating. With the aim of integrating ...
Latest Developments in Industrial Hybrid Machine Tools that Combine Additive and Subtractive Operations
(MDPI, 2018-12-18)
Hybrid machine tools combining additive and subtractive processes have arisen as a solution to increasing manufacture requirements, boosting the potentials of both technologies, while compensating and minimizing their ...
Numerical Model for Predicting Bead Geometry and Microstructure in Laser Beam Welding of Inconel 718 Sheets
(MDPI, 2018-07)
A numerical model was developed for predicting the bead geometry and microstructure in laser beam welding of 2 mm thickness Inconel 718 sheets. The experiments were carried out with a 1 kW maximum power fiber laser coupled ...
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 ...
Laser Dissimilar Joining of Al7075T6 with Glass-Fiber-Reinforced Polyamide Composite
(MDPI, 2020-01-22)
Dissimilar joining between metal and composite sheets is usually carried out by mechanical or adhesive joining. Laser dissimilar joining between metal and composite sheets could be an alternative to these methods, as it ...
Control loop tuning by thermal simulation applied to the laser transformation hardening with scanning optics process
(Elsevier, 2016-04)
Laser transformation hardening with scanning optics (LTHS) is a novel manufacturing process on a very preliminary stage of introducing it in the surface treatment industry. The key to ensure the success in this process is ...
Internal characterization and hole formation mechanism in the laser percussion drilling process
(Elsevier, 2013-09-09)
Laser percussion drilling is increasing its relevance in many industrial applications, being used particularly in the aircraft industry in performing the micro-holes in nickel based alloys turbine blades for cooling, or ...
Evaluation of the relevance of melt pool dynamics in Laser Material Deposition process modeling
(Elsevier, 2017-07-14)
The melt pool dynamics consideration in the numeric modeling of the Laser Material Deposition (LMD) process can be enormously difficult and expensive, especially if this calculation is not strictly necessary. The increased ...
Laser beam welding analytical model when using wobble strategy
(Elsevier, 2020-12-23)
This article presents a model for estimating the thermal gradient, bead geometry, and microstructure in the laser welding process when the Wobble strategy is used. This method combines the main feed motion with a secondary ...
