Today’s computer aided design systems are based on underlying technologies developed over 20 years ago. Although they have become a key part of the design process, and are ubiquitous in industrial product development processes, they usually come into play after the shape of the design has been created. In essence, today’s CAD systems are used to support design evaluation and analysis, and downs...

The meso/micro layered manufacturing technologies have significant implications for the design and fabrication of complex miniature structures. A laser-based additive/subtractive Rapid Manufacturing system is thus developed to build meso/micro structures. By incorporating laser microdeposition and micromachining with a pulsed Nd:YAG laser that has four harmonic wavelengths, this manufacturing s...

engineering design processes. Among these models, one of the most widely known is perhaps the one proposed by Pahl and Beitz [42]. It presents a systematic engineering design approach including four core design phases: product planning and clarifying the task, conceptual design, embodiment design, and detail design. Similarly, Ulrich and Eppinger [43] introduce a more refined design process by ...

The Computer-Aided Manufacturing Engineering (CAME) program is developing a number of integrated software toolkits for design, manufacturing engineering, and production operations [1]. One of these toolkits is the Manufacturing Engineering ToolKit (METK) [2]. The goals of the METK project are 1) to develop generic interface specifications, data structures, information models, and data validatio...

Prevalent area of exploitation of CAM (Computer Aided Manufacturing) systems is computer aided program creating for NC production equipment. However, CAM systems do not sufficiently cover all periods of production process and due to this, the necessity to define the systems of Computer Aided Manufacturing Engineering CAME is obvious. Augmented Reality (AR) mixes virtual world with the actual wo...

Tolerance design plays a major role in the quality of the product life cycle. Its purpose not only can ensure the products quality. At the same time, it monitors the product manufacturing costs. The traditional the tolerance design devotes to the optimization target of minimizing the manufacturing cost. But due to the manufacturing process of a product, there is a nonlinear relation between tol...

Smart manufacturing technologies require a cyber-physical infrastructure to collect and analyze data and information across the manufacturing enterprise. This paper describes a concept for a product lifecycle test bed built on a cyber-physical infrastructure that enables smart manufacturing research and development. The test bed consists of a Computer-Aided Technologies (CAx) Lab and a Manufact...

We describe a synthesis system that takes operating range constraints and inter and intracircuit parametric manufacturing variations into account while designing a sized and biased analog circuit. Previous approaches to computer-aided design for analog circuit synthesis have concentrated on nominal analog circuit design, and subsequent optimization of these circuits for statistical fluctuations...
