... been characterized for high throughput and high quality manufacturing. Therefore, at present it is not possible to (i) predict whether fabricating a part is feasible within the constraints of the desired rate and quality and (ii) select/design equipment appropriate for the desired manufacturing goals...

... components. In this paper, we present an alternative strategy for controlling premolded component deformations. This involves a mesoscale in-mold assembly strategy that has a multigate mold design for bidirectional filling. This strategy permits in-mold assembly using polymers with comparable melting points...

... design optimizations. Effects of outer shielding gas directions, inner/outer shielding gas flow rate, powder passage directions, and opening width on the structure of the powder stream are systematically studied. An experimental setup is designed to quantitatively measure the particle concentration...

...-module database is created to form a selection space, where the machinable geometric features identified in STEP are defined as functional requirements (FR’s) and the structural component modules derived from the conventional machine tools as design parameters (DP’s). An inner FR-to-DP mapping mechanism...

...Jie Chen; Gang Bai; Zhongmin Shen; Xiaofeng Li; David Fulton; Andrew Hsu Failures can occur in brushless alternators due to interferences between the moving and stationary parts, called “rub.” Improper design of component target dimensions and tolerances can result in interferences. A method...

... in mold design. Calculated ejection force was maximum at the beginning of ejection and differed by 10%–16% from experimental values, with the difference being much less over the main part of the ejection process. The maximum number of ejector pins for failed ejection was predicted. The difference between...

...W. Z. Guo; K. He; K. Yeung; R. Du This paper is the second part of our study on designing a new type of metal forming press. In the first part of the study ( Du, R., and Guo, W. Z., 2003, ASME J. Mech. Des., 125(3), pp. 582–592 ), a new controllable mechanical press is introduced that consists...

...J. N. Siddall; Y. Diab A general algorithm is described for obtaining the maximum entropy distribution constrained by moments in functional form. It is based on Jaynes’ principle. The distribution is proposed as a useful tool in probabilistic design. The maximum entropy distribution is generated...
