Methodology for evaluate the form deviations for formula one nose car

The paper presents a measuring strategy for a Formula One car using a Coordinate Measuring Machine (CMM) and a 3D laser scanning devices. The measurement procedures outlined the dimensional deviation of the CAD model and prototype made of composite material. The authors present two methods for the determination of symmetry for components of a Formula One car based on measuring and 3D scanning.

Mold Design for Polystyrene Plastic Anchor

The paper presents the entire process of designing and optimizing an injection mold for a polystyrene plastic anchor. The design process begins with a comprehensive market study of the polystyrene plastic anchors available on the Romanian market, and the results of this study are then used for the creation of a new model of anchor. After this first stage of design, the resulted model is optimized in terms of the injection process using the simulation software Autodesk Moldflow Adviser. After establishing the final form of the polystyrene plastic anchor, the mold is designed in Catia V5 using a series of standardized components. Manufacturing set-up is done in Catia V5 and Cimatron. In the end, the validation of the mold is performed using the injection machine Haitian Mars 2-2500.

Designing a Hybryd Equipment for Additive Manufacturing

In terms of the development of 3D printers we can say that in the first stage of evolution the huge majority of them were able to print 3D using 3 axis numerically controlled. Currently there are several types of printers that can print in 4 and 5-axis developed using classical solutions (portal or parallel structure). Another direction of development is the combination of 3D printers and traditional manufacturing equipment, with an already existing commercial solution (Hermle MPA 40) that combines milling and MPA technology (Metal Powder-Application). This paper presents a hybrid equipment that can be placed in the specific additive manufacturing category, combining milling operations (4 axis) and turning with 3D printing using FDM technology. The machine uses stepper motors for driving kinematic axes, a DC motor (16 000 rev / min) to drive the main shaft of the mill and a three-phase motor for turning. The software used for milling and turning is Mach3, while MatterControl is used for 3D printing.
