(MDPI, 2020-11-12)
The scope of this work is to present a reverse engineering (RE) methodology to achieve accurate polygon models for 3D printing or additive manufacturing (AM) applications, as well as NURBS (Non-Uniform Rational B-Splines) ...
A Series of Vertical Deflections, a Promising Traffic Calming Measure: Analysis and Recommendations for Spacing
(MDPI, 2020-05-13)
Traffic calming measures (TCM) are placed in urban areas to improve road safety, and among them, vertical TCMs are widely employed. Many researches are focused on the influence of the geometry of each measure on speed ...
Semi-Active Magnetorheological Damper Device for Chatter Mitigation during Milling of Thin-Floor Components
(MDPI, 2020-07-31)
The productivity during the machining of thin-floor components is limited due to unstable vibrations, which lead to poor surface quality and part rejection at the last stage of the manufacturing process. In this article, ...
Special Issue on “Machining Dynamics and Parameters Process Optimization”
(MDPI, 2020-12-14)
In 1907, F.W Taylor—the father of production engineering—exposed the fundamentals of modern machining and defined chatter as the most obscure and delicate of all problems facing the machinist [...]
