独立于复合材料CNC自动铺带和铺丝机床的离线编程和模拟
Vericut复合材料模拟(VCS)
VCS读取CAD 模型,读取从Vericut VCP或其他复合材料铺层编程软件生成的NC程序,再在虚拟机床上模拟NC程序控制的铺层过程,通过NC程序指令在虚拟CNC模拟环境下,给铺层添加材料。这些被添加应用到型模上的材料,可以被测量、分析和检测,以确保NC程序遵循制造标准和要求,同时可以自动创建报告,显示模拟结果和数据信息。

Electroimpact, Inc.
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.
