Aston Martin

Aston Martin Racing selects Creo Elements/Pro and Windchill to design and manage development of next generation vehicles

March 2, 2011 By Laura Carrabine Leave a Comment

PTC announced that in an extensive benchmark process Aston Martin Racing selected and implemented Creo Elements/Pro for the 3D CAD design of its racing vehicles and Windchill for product lifecycle management (PLM) in its race car division.

Aston Martin is the only manufacturer that produces a car to compete in every category of the FIA GT Championship sports car racing series. Models range from modified standard vehicles in the GT4, GT3 and GT2 classes – including the high-performance V12 – to the 6.0 litre 600 BHP DBR9 in the GT1 class and the Le Mans prototype LMP1 Aston Martin.

Aston Martin Racing has moved away from its previous third-party chassis strategy to develop its next generation LMP1 from scratch. This new racing vehicle is now being designed and engineered from the ground up using Creo Elements/Pro and Windchill to manage the development process. In addition to the designers, the purchasing department uses Windchill for its request for quotation process, enabling collaboration with suppliers.

Vero help with Artega GT ‘supercar’ production

July 13, 2010 By Laura Carrabine Leave a Comment

DECS GmbH are specialists in the design and manufacture of interior and exterior trim composite components for the automotive industry. Reference customers include Audi, BMW, Lamborghini, Mercedes, and Porsche. DECS GmbH embraces technology and firmly believes in process optimization. It is a combination of these factors that helped their latest project, the Artega GT succeed, and cause a stir in the automotive world.

The Artega GT is a mid-engined, rear wheel drive, high-performance sports car designed by Henrik Fisker, the man responsible for the much celebrated Aston Martin Vantage and the sweeping lines of the BMW Z8. The two-seater GT has an aluminum space frame and carbon fiber reinforced body. Providing the power is a Volkswagen-sourced 3.6L V6 engine reaching 60mph in less than five secs.

Within the framework of this project, DECS GmbH contributed to the manufacture of the front bonnet, tailgate, and roof.  Ulrich Krämer, Managing Director of DECS GmbH explains how the project started. “Artega originally contacted us because we have been involved in a number of projects with other prestige automotive clients and possess the skill and knowledge required for the development of composite components. For the initial pilot project, we first created five parts using a prototype tool. We were then invited to participate in the second phase in which we produced a pre-series set of tooling for the front bonnet and tailgate for testing. After successful pre-series testing, we now manufacture the complete suite of production parts for the front bonnet, tailgate, and roof.”

DECS GmbH produces its polyurethane-based composite components using a honeycomb core. This is especially relevant in the development of automotive interiors as the potential weight reduction is extremely attractive to car manufacturers. Natural fiber-reinforced polyurethanes are being used more and more in the automotive industry and it is now possible to produce parts with wall thicknesses of 1.5 – 2.0 mm – depending on the unit weight of the natural fiber mat used. These end products weigh about 45% less than products created using conventional injection molding materials.

One example of process optimization is the use of Huber & Grimme gantry milling machines, which are equipped with efficient two shaft spindles and tandem work-tables for multi-axis part trimming. Once the body panels are removed from the tool, they are placed onto jigs and fixtures for part trimming and additional CAM operations. All 5-axis operations are programmed using VISI Machining from Vero Software and posted using a Siemens 840D controller. Due to the complex nature of multi-axis machining, NC programs are also simulated prior to running on the shop floor. The simulation checks against the physical machine limits and ensures process-safe tool paths.

The relevant jigs and fixtures are also designed using VISI software and produced at DECS. “VISI is the ideal tool for the construction of the trimming jigs”, explains Krämer. “One advantage is the ability to constantly switch between solid and surface technologies. This is vitally important to us and allows us to follow a flexible design path. VISI provides interfaces to all the significant data formats such as CATIA, UG, Pro/E, STEP, IGES, and SAT and this allows us to handle our clients native CAD data with confidence.”

VISI has been in use at DECS GmbH since 2005 when the software was provided as a solution for simultaneous 5-axis milling to solve a problem that involved the complicated trimming of plastic parts with undercut positions that could not be could be processed with water-jets.
