Simulation and machining software specialist CGTech (Irvine, Calif., USA) will demonstrate the process of programming automated composite machinery. Visitors will be able to see the steps needed to get from a CAD-designed composite part to CNC programs that drive an automated fiber placement (AFP) or automated tape laying (ATL) machine. CGTech will also demonstrate VERICUT composite applications: VERICUT Composite Paths for Engineering (VCPe); VERICUT Composite Programming (VCP); and VERICUT Composite Simulation (VCS).

VCPe measures and evaluates the effects of AFP and ATL path trajectory, material steering, surface curvature, course convergence and other process constraints as they would be applied in manufacturing. It also provides produceability analysis of the fiber angle based on the curvature of the part and overlap and gaps needed for structural analysis.

VCP reads CATIA V5, STEP or ACIS surface models. It also reads Fibersim, CATIA V5, or other external ply geometry and information. VCP then 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.

CGTech will also exhibit its latest version of VERICUT. VERICUT is CNC machine simulation, verification, and optimization software that enables users to eliminate the process of manually proving-out NC programs. VERICUT simulates all types of CNC machining, including drilling and trimming of composite parts, water jet, riveting, robotics, mill/turn, and parallel kinematics.
