All mechanical designs pass through a series of formal and informal redesign steps, involving the analysis of functionality, manufacturability, cost and other life-cycle factors. The speed and eecacy of these steps has a major innuence on the lead time of the product from conceptualization to launching. In this paper we propose a methodology for(More)
In the marketplace of the 21st century, there is no place for traditional \over-the-wall" communications between design and manufacturing. In order to \design it right the very rst time," designers must ensure that their products are both functional and easy to manufacture. Software tools have had some successes in reducing the barriers between design and(More)
The increasing demand for light emitting diodes (LEDs) has been driven by a number of application categories , including display backlighting, communications, medical services, signage, and general illumination. The construction of LEDs is somewhat similar to microelectronics, but there are functional requirements, materials, and interfaces in LEDs that(More)

For machined parts, setup time is a major component of the total time required to manufacture a machined part from a stock. If the number of setups and hence setup time can be reduced, this will not only decrease the manufacturing time, but will also ensure better machining accuracy, require fewer work-holding devices and increase machine usage time. To(More)
Reliability is the ability of a part or product to perform as intended (i.e., without failure and within specified performance limits) for a specified time, in its life cycle application environment. Reliability specification and demonstration is an activity between customers and suppliers. In the absence of proper procedure, this activity may not meet the(More)
Development of prognostic approaches for insulated gate bipolar transistors (IGBTs) is of interest in order to improve availability, reduce downtime, and prevent failures of power electronics. In this study, a prog-nostic approach was developed to identify anomalous behavior in non-punch through (NPT) and field stop (FS) IGBTs and predict their remaining(More)
