Delcam to Show Latest in CADCAM for Composites at SAMPE Exhibition

29 May 2007

Delcam will demonstrate the latest developments in its CADCAM systems for the composites industry at the SAMPE exhibition to be held in Baltimore from 3rd to 6th June.

New features on display will include improved methods for the generation of 2D patterns for prepregs from 3D models of components, more efficient 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.

The Delcam demonstrations will be supported by machining demonstrations on the stand of machine tool supplier CMS. Delcam and CMS have worked closely together to deliver manufacturing solutions to their joint customers and have enjoyed particular success in the boatbuilding industry.

While Delcam’s software is best known for its applications with injection moulded plastics products, it is also used for the design, manufacture and inspection of composites. Delcam say that the software enables companies to maximise their profitability by increasing productivity, improving quality and reducing lead times. 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 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 powerful nesting functionality.

The range of five-axis machining methods in Delcam’s PowerMILL CAM software gives the user better control over cutting conditions as well as helping to minimise excessive movement of the machine head that can reduce machining rates. Five-axis drilling has also been improved to give faster drilling and more comprehensive hole recognition from a wider range of CAD systems.
