Automated process planning for hybrid manufacturing

Modeling of Manufacturing Feature Interactions for Automated Process Planning

This paper analyzes manufacturing feature interactions and presents algorithms for handling feature interactions in manufacturing process planning. A feature precedence network, which specifies the constraints for the machining sequence, and an AND-OR graph, which describes alternative representations, are built. Application of required/optional volumes, the AND-OR graph, and the feature preced...

The development of a novel process planning algorithm for an unconstrained hybrid manufacturing process

The application of state of the art manufacturing processes has always been constrained by the capabilities either from technical limitations such as limited materials and complex part geometries or production costs. As a result, hybrid manufacturing processes – where varied manufacturing operations are carried out – are emerging as a potential evolution for current manufacturing technologies. ...

Generative System for Manufacturing Process Planning

Process Planning for Shape Deposition Manufacturing

Solid Freeform Fabrication (SFF) refers to a class of rapid manufacturing process that builds parts by incremental material deposition and fusion of thin 2-1/2 dimensional layers. Over this past decade, SFF has taken the manufacturing industry to new heights. However, parts produced by SFF processes exhibit a stair-step surface texture due to the presence of 2-1/2 dimensional layers and exhibit...

A Constraint Engine for Manufacturing Process Planning

We present a constraint-based model and planning engine for manufacturing process planning. By exploiting the expressive power of constraint programming (CP), all relevant, sometimes conflicting pieces of domain knowledge are represented. The planner applies standard propagation techniques and customized search to find cost-optimal solutions in presence of hard, soft and conditional constraints...
