Machining features and algorithms for set-up planning and fixture design

In this research, the approaches of machining feature-based design and precedence matrix algorithm are combined to automate the process planning task and to generate the machining groups for set-ups. The objective of the presented algorithm is overcome the shortcomings of existing CAPP systems. Parts are described in terms of machining features which consist of geometric and non-geometric information linked to design and manufacturing. Machining feature based-design provides the component description to the process planning which consists of attributes required for automation.
