Delcam will demonstrate the latest developments in its CADCAM systems for the composites industry at the Composites Europe exhibition.
Special features on display for the design and manufacture of composite components will include methods for the generation of 2D patterns for prepregs from 3D models of components, improved nesting to ensure the most economic use of materials cut from sheet and an increased range of five-axis machining methods, both for the manufacture of patterns and tooling and also for the trimming and drilling of moulded parts.
While Delcam’s software is best known for its applications with injection moulded plastics products, it is also used extensively for the design, manufacture and inspection of composites. It is said to offer particular benefits in the development of products where aerodynamics or ergonomics are key considerations and in the manufacture of all types of tooling, including moulds and patterns.
Applications include the manufacture of composite components for the autosport and luxury car industries, the production of aerospace lay-up tools, and the machining of patterns and tooling for compression moulding and reaction injection moulding.
The methods for the generation of 2D patterns from 3D CAD models within Delcam’s PowerSHAPE CAD system are based on un-wrapping techniques first developed for the footwear industry to allow the cutting of leather shapes from shoe designs. They provide quick and easy methods for the creation of the prepreg designs needed for the manufacture of complex, curved shapes. The 2D patterns can then be arranged to give the most cost-effective use of material with Delcam’s nesting functionality.
