Title : Study on the Influence of Cutting Conditions on Machining Surface Quality When Cutting with the FA4060 Milling Machine Authors : Dang Van Truong, Nguyen Van Thinh, Nguyen Xuan Luan, Nguyen Duc Loi
Abstract :
This paper investigates the influence of technological parameters such as spindle speed n and feed rate F on the surface quality of cuts during milling. Experiments were conducted using a CNC milling machine FA4060 with 6 mm thick mahogany wood. Surface quality was evaluated through the surface roughness of the cut. The Taguchi experimental design method was used to assess the influence of each individual parameter on surface roughness. The minimum surface roughness achieved was 1.059 µm corresponding to a spindle speed of 12000 RPM and a feed rate of 200 mm/min. Analysis using the Taguchi method showed that surface roughness was mainly affected by the feed rate, while spindle speed had less influence. |

Title : Research, Design, and Manufacture of a Model Frame Integrating Electronic Fuel Injection and Ignition Systems for Modern Automobiles Authors : Vu Thi Phuong, Do Thi Khanh Hoa
Abstract :
This paper presents the research results, design, and fabrication of a frame model integrating an electronic fuel injection and ignition system for automotive engineering education. The development of electronic engine management systems requires training equipment that allows learners to simultaneously observe the hardware structure, signal pathways, and control relationships among the ECU, sensors, and actuators. Based on an analysis of pedagogical and structural requirements, the authors selected a welded box-steel frame solution, developed a 3D model using Inventor, evaluated strength and stiffness using ANSYS R19.5, and carried out fabrication and assembly of the experimental model. The results show that the frame ensures sufficient rigidity and convenience for arranging the ECU, fuel injectors, ignition coils, sensors, and electrical circuit boards. After assembly, the model enables direct observation, measurement, and simulation of the fuel injection–ignition process in a visual manner. The model demonstrates good applicability in teaching, diagnostic practice, and research on modern gasoline engine control systems. |
