Study on Creating Method of Complex Coons Surface Based on Different Chaining Modes

Complex surface has different shapes and complex boundaries, so its creation is always a difficulty of CAD while the manual chaining coons surface of MasterCAM provides a good solution. However, manual chaining is a complex process. Poor understanding of chaining mode will easily cause wrong selection of lines, thus making it impossible to create complex coons surface. This paper starts from the chaining mode and analyzes the approaches to creation of complex coon’s surface.
