Improving Stability Prediction in Peripheral Milling of Al7075T6
(MDPI, 2018-08)
Chatter is an old enemy to machinists but, even today, is far from being defeated. Current requirements around aerospace components call for stronger and thinner workpieces which are more prone to vibrations. This study ...
Sensitivity Analysis of Tool Wear in Drilling of Titanium Aluminides
(MDPI, 2019-03-06)
In the aerospace industry, a large number of holes need to be drilled to mechanically connect the components of aircraft engines. The working conditions for such components demand a good response of their mechanical ...
Multioperation capacity of parallel manipulators basing on generic kinematic chain approach
(Elsevier, 2017-06-07)
The idea of designing multioperation mechanisms capable of performing different tasks has gained prominence in the last years. These mechanisms, commonly called reconfig- urable mechanisms, have the ability to change their ...
Parallel manipulators: practical applications and kinematic design criteria. Towards the modular reconfigurable robots
(Springer, 2017-06-10)
Modern robotic manipulators play an essential role in industry, developing several tasks in an easy way, enhancing the accuracy of the final product and reducing the executing time. Also they can be found in other fields ...
Super Abrasive Machining of Integral Rotary Components Using Grinding Flank Tools
(MDPI, 2018-01-01)
Manufacturing techniques that are applied to turbomachinery components represent a challenge in the aeronautic sector. These components require high resistant super-alloys in order to satisfy the extreme working conditions ...
Comparison of Flank Super Abrasive Machining vs. Flank Milling on Inconel® 718 Surfaces
(MDPI, 2018-09)
Thermoresistant superalloys present many challenges in terms of machinability, which leads to finding new alternatives to conventional manufacturing processes. In order to face this issue, super abrasive machining (SAM) ...
Effective Position Control for a Three-Phase Motor
(MDPI, 2020-02-01)
This document presents an efficient proportional derivative (PD) position controller for three-phase motor drives. The regulator has been designed in frequency domain, employing the direct–quadrature (<i>d</i>&ndas ...
Thermal Diffusivity Measurement of Laser‐ Deposited AISI H13 Tool Steel and Impact on Cooling Performance of Hot Stamping Tools
(MDPI, 2020-01-20)
Additive manufacturing is a technology that enables the repair and coating of high‐addedvalue
parts. In applications such as hot stamping, the thermal behavior of the material is essential
to ensure the proper operation ...
Oscillating U-Shaped Body for Underwater Piezoelectric Energy Harvester Power Optimization
(MDPI, 2019-10-30)
Vibration energy harvesting (VeH) techniques by means of intentionally designed mechanisms have been used in the last decade for frequency bandwidth improvement under excitation for adequately high-vibration amplitudes. ...
The Gender Perspective of Professional Competencies in Industrial Engineering Studies
(MDPI, 2020-04-07)
Sexism and gender relations in higher education require special attention and are a topic of great interest in regulations related to education. The low participation percentage of women in Science, Technology, Engineering, ...
