Prediction Methods and Experimental Techniques for Chatter Avoidance in Turning Systems: A Review
(MDPI, 2019-11)
The general trend towards lightweight components and stronger but difficult to machine materials leads to a higher probability of vibrations in machining systems. Amongst them, chatter vibrations are an old enemy for ...
Hole Making by Electrical Discharge Machining (EDM) of -TiAl Intermetallic Alloys
(MDPI, 2018-07)
Due to their excellent strength-to-weight ratio and corrosion and wear resistance, gamma-TiAl alloys are selected for aerospace and automotive applications. Since these materials are difficult to cut and machine by ...
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 ...
On the effects of cutting-edge angle on high-feed turning of Inconel 718© superalloy
(Springer, 2023-04)
Machining processes on heat-resistant superalloys—i.e., turbine cases, rings, or shafts—are challenging tasks. The high-added value of such parts makes cycle times be longer than expected. Recently, high-feed turning ...
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) ...
The influence of cutting edge microgeometry on the broaching of Inconel 718 slots
(Elsevier, 2023-12)
In aero-engine production, the dovetails (firtrees) of turbine discs are manufactured by broaching. Introducing innovative micro-geometry modifications to broaching tools can significantly influence cutting force, energy ...
Early detection of tool wear in electromechanical broaching machines by monitoring main stroke servomotors
(Elsevier, 2023-12)
This paper aims to provide researchers and engineers with evidence that sensorless machine variable monitoring can achieve tool wear monitoring in broaching in real production environments, reducing production errors, ...
A Cleaner Milling Process Replacing Emulsion Coolant by Cryogenics CO2
(Springer Nature, 2024-01)
In manufacturing sector, looking for a balance between environmental and technical efficiency taking into account productivity is mandatory. Some sectors, such as the biomedical manufacturing sector, also needs to consider ...
