Virtual Prototyping

Computer-aided design (CAD) and computer-aided modeling (CAM) systems have become ubiquitous in virtually all sectors of science and engineering and are the preferred mode of design in most industries. Thus far, CAD/CAM systems have been viewed primarily as vehicles for constructing models of complex objects, and less as tools for analyzing or manipulating the models once they exist. However, present technology is advanced enough that extremely complex objects can be designed almost entirely within CAD/CAM systems, e.g., the Boeing 777, and it is now time to augment these systems with methods for performing useful operations on the (existing) models. For each of the various application domains that utilize CAD/CAM, there are many geometric operations one might desire to perform on/with the resulting models. There are many geometric problems in manufacturing for which integrated CAD/CAM solutions would be valuable.

The goal is to make virtual prototyping truly possible, that is, to perform all stages of product development within a CAD/CAM system. Although current technology is often sufficient for constructing the geometric models, there are many tasks in the development cycle that still must be performed manually. In particular, products usually have specified maintenance or usage requirements. For example, spark plugs should be easy to remove from an engine and the interior controls of a car should be within reach of the driver, regardless of his/her size. Typically, such requirements are tested after the product is designed (often with a physical model), and if they are not met, a re-design phase is initiated. Clearly, CAD/CAM systems able to verify such properties would decrease both the time and cost associated with product development. Another example is in assembly sequencing - determining if it is possible, and in what order, to assemble a system from its disparate parts or subassemblys. In many cases, the opposite disassembly problem problem is considered instead.
