CGTech (Irvine, Calif., USA) has announced that it will present the latest developments in composite fiber placement programming and simulation at the CompositesWorld Expo 2009. The presentation will be given by CGTech's product marketing manager, Bill Hasenjaeger, in the Advanced Track on Monday, Sept. 28, 2009 at 10:30 am. The CompositesWorld Expo 2009 show takes place Sept. 28-30 at the Renaissance Schaumburg Hotel and Convention Center in Schaumburg, Ill., USA.

Most users of CNC automated fiber placement (AFP) machinery use offline NC programming software delivered with their machine, forcing companies to adopt multiple software applications for multiple brands of machines. Hasenjaegerís presentation will discuss the implementation and use of machine-independent, off-line NC programming software as it applies to CNC fiber placement machines.

"The more mature CNC metal-cutting industry started the same way, but has now evolved into a clear separation and cooperation between independent software and machine suppliers," Hasenjaeger said. "This frees the company to select the best machine for the job, while using one software application to create NC programs for a variety of machine brands."

During the exposition, CGTech will demonstrate VERICUT Composite Applications: VERICUT Composite Programming (VCP) and VERICUT Composite Simulation (VCS) in booth 300. VCP reads CAD surfaces and ply boundary information and adds material to fill the plies according to user-specified manufacturing standards and requirements. Layup paths are linked together to form specific layup sequences and are output as NC programs for the automated layup machine.

VCS reads CAD models and NC programs, either from VCP or other composite layup path-generation applications, and simulates the sequence of NC programs on a virtual machine. Material is applied to the layup form via NC program instructions in a virtual CNC simulation environment. The simulated material applied to the form can be measured and inspected to ensure the NC program follows manufacturing standards and requirements. A report showing simulation results and statistical information can be automatically created.

CGTech will also exhibit the latest version of VERICUT CNC machine simulation and optimization software. VERICUT 7.0 features significant performance-improving enhancements that reduce the time required for manufacturing engineers to develop, analyze, inspect and document the CNC programming and machining process. Instead of focusing on new features or add-on modules, CGTech developer resources have focused on diligent code optimization and customer-driven enhancements.
