Electric-motion in Romania — Overview: Study on machining parameters of EV charging station mechanical components
This paper presents some relevant aspects of charging infrastructure for electric vehicles in Romania. It evidences the charging station and fast charging stations designed and installed by the first Romanian company dedicated 100% to e-mobility, E-Motion Electric. Also, a study on machining (milling) parameters of some mechanical components of electric vehicle (EV) charging station is done and, finally, the regression model for these parameters is determined. This model would be further used for machining process optimization.
Modelling and Controlling of Machining Forces when Milling Polymeric Composites
Polymeric matrix composite materials are used when high characteristics are needed, good resistance under severe working conditions and low specific weight. Implementing polymeric matrix composite materials, specially, glass reinforced ones, resulted in the substituting of classical materials, whose quantities are more, and more, limited. Composite material products can be obtained to their final shape when manufacturing or, when necessary, can be submitted to further machining processes. Polymeric matrix composite materials can be conventionally machined (cutting, turning, drilling, milling or broaching) or / and non-conventionally machined (laser, ultrasound, etc.). Researches on milling machinability of glass fibers reinforced polymeric composites are at their very beginning, in our country, this paper pointing out some important aspects of research on cutting forces in cylindrical-face milling. There is also presented a data measuring, acquisition and processing system for the experimental model, as well as a real time control scheme designed to determine the measuring errors.
Glass Fibres Reinforced Polymeric Composites - Statistic Models of Surface Roughness
Due to their important and special characteristics composites have known a continuous development lately. Consequently there has been given great attention to improve, both, their manufacturing and machining technologies. In machining, milling represents an important procedure and, as there are not many data concerning process parameters dependence, some statistic models were considered worth to be determined. So, there has been studied Romanian glass fiber reinforced polymeric composites and have been obtained two mathematical relations of surface roughness dependence - R a parameter- on some milling process variables.
