Influence of PLA Filament Conditions on Characteristics of FDM Parts
(MDPI, 2018-08)
Additive manufacturing technologies play an important role in Industry 4.0. One of the most prevalent processes is fused deposition modelling (FDM) due to its versatility and low cost. However, there is still a lack of ...
Mean Stress Effect on the Axial Fatigue Strength of DIN 34CrNiMo6 Quenched and Tempered Steel
(MDPI, 2018-04)
The present study consists of a theoretical and experimental investigation of the effect of axial mean stresses on the high cycle fatigue behaviour of DIN 34CrNiMo6 high strength steel in quenched and tempered conditions. ...
Analysis of the Process Parameter Influence in Laser Cladding of 316L Stainless Steel
(MDPI, 2018-09)
Laser Cladding is one of the leading processes within Additive Manufacturing technologies, which has concentrated a considerable amount of effort on its development. In regard to the latter, the current study aims to ...
Retained Austenite Control for the Soft Machining of High-Hardness Tool Steels
(MDPI, 2018-07-23)
Most high-hardness tool steels comprising forming dies require expensive finish machining operations to compensate for the dimensional distortion and surface oxidation caused by the die heat treatment. Precipitation-hardening ...
Wear And Friction Evaluation Of Different Tool Steels For Hot Stamping
(Hindawi, 2018-03-26)
The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a ...
Development of a Test-Bench for the Accurate Positioning of Scintillation Detector Modules for Medical Imaging Applications
(Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2018)
When assessing the impact of novel concepts of scintillation block detectors for PET tomography by measuring the performance of single modules, or one module in coincidence with another, it is not trivial to translate the ...
Mechatronic Model Based Jerk Optimization in Servodrives with Compliant Load
(Springer Nature Switzerland AG, 2018-08-02)
The aim of this work is to develop a mechatronic model for servodrives that move a compliant load, which is the case of large heavy machine tools. The model integrates the dynamics of the motor, transmission chain and ...
Evaluation of the Bond-to-Concrete Properties of GFRP Rebars in Marine Environments
(MDPI, 2018-10-08)
Increased traffic in combination with growing environmental impacts have led to the accelerated degradation of built infrastructure. In reinforced concrete structures, the corrosion of steel reinforcement is the predominant ...
A robot for welding inspection in offshore mooring chains
(Springer, 2018-08-31)
In this paper, the authors present the CIRUS robot. This automatic system uses a combination of pulse-echo and pitch and catch ultrasonic strategies for the inspection of the welded area of mooring chain links in an automatic ...
A robot for non-destructive testing weld inspection of offshore mooring chains
(SAGE Publications Inc., 2018-05-09)
Welding flaw detection is a key step in manufacturing many components. In offshore chains, every link is manufactured from a steel bar that is bent and the ends joined by flash butt welding. Ultrasonic inspection of the ...
