Machining Simulation of Novikov Profile Gear Models for Analysis and Computational Calculations
Published on 2025-03-05 by Pawe? Fudali, Tadeusz Markowski, Jacek Pacana @MDPI
Abstract: The paper presents the process of preparing gear models with an original profile for numerical analyses. We used solid modeling reflecting the gear cutting using the enveloping generation method. A script was prepared in AutoCAD to enable automatic simulation of the material removal process and obtain precise gear models. The analyzed gears had geometry based on Novikov’s engagement; however, during the tool design, the tooth profile was adjusted due to the incorrect values of cert[...]
Our summary: The paper describes the process of preparing gear models with an original profile for numerical analyses using solid modeling. A script in AutoCAD enables automatic simulation of the material removal process to obtain precise gear models with circular-arc tooth profiles. Gears models are used for finite element method calculations in ANSYS and analysis of the contact pattern and stress state in a loaded gearbox.

Case Study of Pula Airport
Published on 2025-02-27 by Jelena Pivac, Igor �timac, Dajana Bartulovi?, Ivan Lonjak @MDPI
Abstract: Today’s airport passenger terminals are required to be planned and designed to ensure flexibility for future adjustments at minimal cost, but also to respond to changes in demand and/or needs of passengers, airlines, and aircraft. To achieve these goals for airports and their operators, planning must be flexible and balanced. Recent data show that the airline business model of low-cost carriers continues to grow, especially after the pandemic. The analysis of the passenger traffic [...]
Our summary: Planning flexible airport terminals for future adjustments. Analysis of airline business models and passenger traffic demand. Guidelines for future airport terminal planning based on forecasts.

A Layered Framework for Universal Extraction and Recognition of Electrical Diagrams
Published on 2025-02-20 by Weiguo Cao, Zhong Chen, Congying Wu, Tiecheng Li @MDPI
Abstract: Secondary systems in electrical engineering often rely on traditional CAD software (AutoCAD v2024.1.6) or non-structured, paper-based diagrams for fieldwork, posing challenges for digital transformation. Electrical diagram recognition technology bridges this gap by converting traditional diagram operations into a “digital” model, playing a critical role in power system scheduling, operation, and maintenance. However, conventional recognition methods, which primarily r[...]
Our summary: A novel layered framework is introduced for universal extraction and recognition of electrical diagrams, addressing challenges faced by traditional CAD software and paper-based diagrams. Improved models and algorithms are employed to accurately segment diagram objects, recognize text, and repair connection relationships, outperforming existing approaches in robustness and universality.

Development of a Customized 3D Printed Orthosis for Non-Surgical Treatment of Olecranon Elbow Fractures
Published on 2025-02-11 by Dante Rodriguez, Catherine Boggio, Melany Cama, Joao Torres, Gianella Ccama, Emilio Ochoa, Andoni R. Molina @MDPI
Abstract: Elbow injuries are the second most common upper extremity fractures and often require invasive and costly surgical treatments. To explore a non-surgical alternative, we present the development and evaluation of a custom 3D-printed static orthosis made from polylactic acid (PLA) designed using 3D scanning, CAD software-based modeling and material characterization, showing promise for broader application in similar elbow injuries.[...]
Our summary: Development of custom 3D-printed orthosis for non-surgical treatment of olecranon fractures. Static orthosis made from PLA designed with 3D scanning and CAD software. Promising alternative for elbow injuries.

Effect of Infill Density on the Mechanical Properties of Natural Peek Processed by Additive Manufacturing
Published on 2025-01-27 by Efr�n V�zquez-Silva, Jonnathan Andr�s Pintado-Pintado, Freddy Patricio Moncayo-Matute, Pa�l Bol�var Torres-Jara, Diana Patricia Moya-Loaiza @MDPI
Abstract: In the present investigation, the mechanical properties of natural polyether-ether-ketone (PEEK), processed by additive manufacturing applying fused deposition modeling (FDM) with three different infill densities, are investigated. Mechanical characterization was performed through destructive testing. Specimens were designed in CAD software and printed with controlled infill densities of 40%, 70%, and 100%, using a rectilinear pattern. The results showed that increased infill density improves me[...]
Our summary: Effect of infill density on mechanical properties of natural PEEK processed by additive manufacturing.
