The availability of low-cost computational power is a driving force behind the growing sophistication of CAD software. Tools designed to reduce time-consuming build-test-redesign iterations are essential for increasing ...

The ability to quickly introduce new quality products is a decisive factor in capturing market share. Because of pressing demands to reduce lead time, analyzing the manufacturability of the proposed design has become an ...

Since best-first search algorithms such as A* require large amounts of memory, they sometimes cannot run to completion, even on problem instances of moderate size. This problem has led to the development of limited-memory ...

Decisions made during the design of a machined part can significantly affect the product's cost, quality, and lead time. Thus, in order to address the goals of concurrent engineering, it is important to evaluate the ...

Although AI planning techniques can potentially be useful in several manufacturing domains, this potential remains largely unrealized. Many of the issues important to manufacturing engineers have not seemed interesting to ...

For machining purposes, a part is often considered to be a feature-based model (FBM), i.e., a collection of machining features. However, often there can be several different FBM's of the same part. These models correspond ...

Chapman's paper, "Planning for Conjunctive Goals", has been widely acknowledged as a major step towards understanding the nature of nonlinear planning, and it has been one of the bases of later work by others -- but it is ...

In research on concurrent engineering and engineering design, the increasing use of design for manufacturability(DFM) is expanding the scope of traditional design activities in order to identify and eliminate manufacturing ...

This paper describes a new admissible tree search algorithm called Iterative Threshold Search (ITS). ITS can be viewed as a much-simplified version of MA*[2], and a generalized version of MREC [15]. ITS's node selection ...

Manufacturing features and feature-based representations have become an integral part of research on manufacturing systems, largely due to their ability to model correspondences between design information and manufacturing ...
