Quick response the name of the game in F1

Followers of Formula 1 will be delighted by Jenson Button’s victory at the Canadian Grand Prix in Montreal. Sebastian Vettel is human after all, overshooting a bend and letting Jenson pass on the last lap – thrilling stuff. It had me on the edge of my seat anyway!

What has this got to do with a CAM software blog you might ask? Quite a lot as it happens, as the leading teams are making changes to their cars right up to the last-minute, testing new wings, engine parts, diffusers etc. to gain valuable 1/10ths of seconds. To achieve these changes relies on a fast-moving supply chain that can respond in the space of a few hours, taking new design data and turning it into a high technology finished product without a hitch. In this industry, they don’t take no as an answer. I went to a presentation at Williams F1 a little while ago, and the speaker there pointed out that F1 was primarily an entertainment industry, which had not occurred to me before, so the staggering amounts of money involved and the pressure for success become clear when you think about it in that light.

Back to CAM software – for those supplying this industry speed, reliability, trouble-free operation and technical competence are essential elements. Suppliers can’t have a software package which is difficult to program or which won’t machine a new and complex shape or which produces unreliable CNC code. Choosing the best CAM software takes on a whole new significance in this industry as if it causes an avoidable delay it can result in lost business and the customer going elsewhere. Software that has been designed with reliability, ease of use and technical competence in mind will make programming the machines, quick, simple and trouble-free, enabling companies to spend time optimizing other parts of their production cycle.

UK motorsport stands to win from parallel computing

Although there has been a decline in passenger car manufacture in the UK, it is recognised as a world leader in motorsport technology. The majority of the leading F1 teams have their research and development facilities in the country, and a large proportion of the engineers in all the teams is British. The strength of the UK motorsport industry was shown at the last month’s Autosport show in Birmingham, where trade visitors and the public could see some of the latest manufacturing innovations in the industry.

For some of the complex parts used in the cars, machining times can be several hours, requiring copious amounts of NC data, especially where 5-axis CNC machining has been introduced. To create this amount of CNC code requires a considerable amount of computing power.

Now that multi-processing computers are available, CADCAM companies are making the most of this technology to speed up the calculation times, through parallel computing, in their software. Sescoi’s WorkNC V21 CAM software, which launched in the UK at Autosport, produces speed improvements of up to 10 times.

Being able to carry out several calculations simultaneously is not a trivial task for developers, as algorithms have to be split up into smaller sections and the dependency between these calculations needs to be considered to ensure that they are done in the correct order.

For complex components, parallel computing will make a significant time saving in toolpath preparation, so the ability to produce the necessary CNC code faster will make it easier for companies involved in motorsport to satisfy the delivery requirements of their customers, and keep their teams winning.
