vcpVCP lit les surfaces CAO ainsi que les informations de limite d’épaisseur et crée les parcours de placement de fibres pour remplir les épaisseurs selon les normes de fabrication et les exigences spécifiées par l’utilisateur. Les parcours des plis de composite sont reliés ensemble pour former des séquences spécifiques de couches de composite et sont post-processés pour la machine AFP/ATL.

Electroimpact Selects CGTech to Provide Machine Independent AFP Programming Software

Excerpt from:  High-Speed Fiber Placement on Large Complex Structures

Programming of AFP machines is critical. Traditionally, the machine tool vendor has delivered AFP programming systems. However machine tool vendors do not generally excel at the type of programming required for an AFP programming system, or at providing updates for new operating systems, CAD software or computing hardware platforms.

Spirit AeroSystems has recognized the need for programming software to be provided by an industry recognized software provider as part of a standard suite of regularly updated and maintained software. The delivery of machines by competent machine tool vendors, with the delivery of programming systems by competent software vendors, mirrors practices in the mature metal removal industry. In that industry machine tool vendors by and large no longer attempt to compete with far more competent programming companies like Mastercam, Gibbs and others.

Electroimpact recognized CGTech, with their Vericut Suite of software, as being very capable to provide machine independent AFP programming software. For over 2 years Electroimpact has been in a non-exclusive partnership with CGTech to develop AFP programming software called the « Vericut Composite Programming and Simulation Suite ». Major aircraft manufacturers and their partners have tested this programming software over the last 2 years, and it will be used by Spirit Aerosystems to program these new AFP machines. The software will be updated and maintained by CGTech. For further information on the programming system contact CGTech.

The addition of a mathematically rigorous programming system has been demonstrated to eliminate end placement errors sometimes seen on machine tool manufacturer-developed programming systems. These programming system errors appear most frequently in tow convergence areas. They occur less frequently at ply boundaries.
