Delcam's PowerMILL chosen for A1 Grand Prix engine manufacture by Zytek

1 February 2005

Delcam's PowerMILL CAM system has been chosen by Zytek Engineering, a specialist in automotive control systems, race engine design and development, powertrain development and hybrid-electric vehicles, for the manufacture of all engines for the new A1 Grand Prix series.
This follows the award of a three-year contract to Zytek to supply all the engines and electric gear-shift systems for the new racing series that is scheduled to start in September.
Zytek was awarded a contract by the Fédération Internationale de l'Automobile (FIA) in 1995, to supply and support all the engines used by Formula 3000 competitors worldwide. The success, in particular the reliability, of these engines has greatly reduced the cost of competing in this series and led to the renewal of the contract in 1998 and in 2001.

The A1 Grand Prix contract will demand a different approach to engine manufacture, according to Zytek production manager, Ian Edmonds. "With the current ZG348 sports car engines, there are regular design changes so each component is produced in small quantities or even as a one-off. For the new A1 Grand Prix series, each team must have exactly the same engine so we will have to produce at least 40 identical examples," he explains. "We realised that we would need to speed up our manufacturing techniques, especially the time we were taking to machine the engine ports, in order to produce these increased volumes.
"One change that we wanted to introduce was continuous five-axis machining, instead of using only positional five-axis techniques. We had these capabilities on some of our six Mori Seiki machines. However, our CAM system was unable to produce continuous five-axis toolpaths so we needed to look for an alternative."
The biggest benefit expected from the Delcam software is in machining efficiency. "We are looking to reduce the time for finish machining of the engine ports by two-thirds," says Edmonds. "Our early results have shown that this is an achievable target."
Zytek was founded in 1982 to develop and manufacture innovative electronic technologies for the exacting world of motor racing. The company has been responsible for many race-winning innovations, including the first digital engine management system for Formula One. Although best known for its success on the racetrack, Zytek has also worked with some of the leading names in performance motoring, including Aston Martin, Jaguar, Rolls-Royce and Bentley.
In addition to its contribution to Formula 3000, the Zytek Engineering performance engines business has also provided championship winning BMW four cylinder engines to the BTCC series and six cylinder M5 engines to BMW of North America, winning the IMSA Supercar Championship in 1994 and 1995, as well as providing engines for the very successful Zytek 04S Le Mans Prototype Sportscar.
