The notch effect in Polyurethane materials of different densities is investigated. Tensile specimens with lateral V and U symmetric notches and with holes of different diameters were tested. The material parameters inherent stress and critical distance are determined using a linear elastic finite element analysis in conjunction with experimental results of average maximum load. The paper proposed...
Intelligent machining means a blend between machining processes (turning, milling, drilling, grinding) and sensors, intelligent monitored by hardware and software applications dedicated to this task. From hardware point of view, today the sensors are incorporated by default in all machining equipments, but the intelligence is mostly human. Further researches try to replace the human decisions with...
Our research was focused on a Product Life Management (PLM) system implementation in a digital manufacturing environment. We simulated in our laboratory the perspectives to put into operation a PLM system, to help the decision process in a CAD/CAM/CAE developing process. We analyzed different PLM systems and the measured parameters are: number of the objects manipulated; the price of server installation...
The design of machine tools activity is an area with hundreds of years old. With the development of CAD/CAE systems, the engineers' work was greatly simplified. However, CAD/CAE systems are unable to overcome a critical threshold, thereby leaving the designer with many problems to be solved. Artificial intelligence field is also very exciting to develop this area. This paper presents a first attempt...
