Practical CAD Techniques for Composite Pattern/Mould Design

Composites video tutorial from Easy Composites covering the design principles and practical CAD techniques required when preparing 3D models for CNC machining into composite patterns. In the tutorial, we’re using Autodesk Fusion 360, although the tools and processes are generic and would apply equally to any other engineering CAD package such as Catia, Solidworks or Onshape.

The tutorial begins by looking at the more basic steps of checking draft angles, adding trim allowance, closing apertures, creating flanges and setting up the stock material. The second half of the tutorial looks at a more complex ‘split-mould’ and covers the process of using draft analysis to create the optimum parting line, as well as design-in features such split-mould clamping bushes.
