Planning for Machining Workpieces with a Partial-Order, Nonlinear Planner
Juergen Paulokat, Stefan Weß · 1999
We describe a hybrid architecture supporting planning for machining workpieces. The architecture is built around CAPlan, a partial-order nonlinear planner that represents the plan already generated and allows external control decision made by special purpose programs or by the user. To make planning more efficient, the domain is hierarchically modelled. Based on this hierarchical representation, a case-based control component has been realized that allows incremental acquisition of control knowledge by storing solved problems and reusing them in similar situations. Introduction Planning for machining workpieces is a crucial step in the process chain of product development in mechanical engineering because it strongly influences the overall product's costs. Its task is selecting and ordering machining operations such that all features of a given workpiece can be manufactured by minimal or, at least, by low costs. Seen Abstractly, every machining operation is composed of several prepar...
