Information : Composite Ply Pattern Generation
Bell Helicopter Textron, Inc. (BHTI) is automating the process of composite ply perimeter generation. This process is accomplished through the use of component surface models. Surface information is created for each ply of the component using CATIA software. Flat patterns for the various plies are then automatically created from these models using BHTI developed software.
Perimeter data for the flat patterns created using CATIA software are translated into CADAM format. The CADAM data is used in a pattern nesting program, and to drive a Gerber Instrument composite fabric cutter.
This procedure significantly reduces the chance of errors and the time required to develop composite layer patterns. Good results have been achieved with ruled surfaces and compound curved surfaces. Flat pattern generation for complex surfaces is currently being investigated.
