Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe
(2021-07-14)
Article
Open AccessIn this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ... -
Study of the influence of the manufacturing parameters on tensile properties of thermoplastic elastomers
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-01-31)
Article
Open AccessAdditive manufacturing (AM) has increased its field of application, not only for prototypes but also for final parts. Therefore, the need of study new materials is currently growing. This paper aims to study the effect of ... -
Derivation of the coefficients in the Coulomb constant shear friction law from experimental data on the extrusion of a material into V-shaped channels with different convergence angles: new method and algorithm
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-01-27)
Article
Open AccessFriction plays an important role in metal-forming processes by pressure and largely controls material flow wear, adversely affecting the wear resistance of dies employed to form metals. Therefore, the combined Coulomb ... -
3D printed surgical planning prototype manufactured by a hybrid multi-material 3D printer
(Institute of Physics (IOP), 2021-10-01)
Article
Open AccessSurgical planning is a preoperative method of pre-visualization that is carried out before or during a surgical intervention in order to achieve the best outcome. This can be done either image-based or hands-on. Regarding ... -
Multi-Objective Optimization of Material Removal Rate and Tool Wear in Rough Honing Processes
(2022-01-24)
Article
Open AccessThis study focuses on obtaining regression models for material removal rate and tool wear in rough honing processes. For this purpose, experimental tests were carried out according to a central composite design of experiments. ... -
Research on desktop 3D Printing Multi-Material New Concepts
(Institute of Physics (IOP), 2021-10-25)
Article
Open Access3D printing or Additive Manufacturing (AM) was originally born as a mono-material technology. And, nowadays, most of the applications are still using only one material. AM has a lot of potential but has not yet been fully ... -
Evaluation of porosity in 3D printed trabecular bone structures for prostheses
(Institute of Physics (IOP), 2021)
Article
Open AccessHip prostheses require an external porous area in order to fix them by means of osseointegration. Different structures can be printed in order to favour bone fixation, such as octet-truss or trabecular, among others. In ... -
Recent advances in the extrusion methods for ceramics
(Institute of Physics (IOP), 2021)
Article
Open AccessIn recent years, extrusion 3D printing processes have undergone an important development. They allow obtaining complex shapes in an easy way and relatively low cost. Different plastic materials can be 3D printed with the ... -
Titanium based bone implants production using laser powder bed fusion technology
(Elsevier, 2022-03)
Article
Open AccessAdditive manufacturing (AM) enables fully dense biomimetic implants in the designed geometries from preferred materials such as titanium and its alloys. Titanium aluminum vanadium (Ti6Al4V) is one of the pioneer metal ... -
Modeling of the influence of input am parameters on dimensional error and form errors in pla parts printed with fff technology
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-11-27)
Article
Open AccessAs is widely known, additive manufacturing (AM) allows very complex parts to be manufactured with porous structures at a relatively low cost and in relatively low manufacturing times. However, it is necessary to determine ... -
Optimization and sensitivity analysis of the cutting conditions in rough, semi-finish and finish honing
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-12-23)
Article
Open AccessHoning processes are currently employed to obtain a cross-hatched pattern on the internal surfaces of cylinders that favors oil flow in combustion engines or hydraulic cylinders. The main aim of the present paper is to ... -
Hot working behaviour and processing maps of duplex cast steel
(2021-07-28)
Article
Open AccessIn this paper the hot working behaviour of medium carbon duplex cast steel is studied using uniaxial hot compression tests over a temperature range varying from 700 °C to 1 000 °C and at different strain rates ranging from ...
