Title of Dissertation: ALGORITHMS FOR GENERATING MULTI-STAGE MOLDING PLANS FOR ARTICULATED ASSEMBLIES Alok K. Priyadarshi, Doctor of Philosophy, 2006 Dissertation directed by: Associate Professor Satyandra K. Gupta Department of Mechanical Engineering Plastic products such as toys with articulated arms, legs, and heads are traditionally produced by first molding individual components separately...

In the paper, analyzing the tread flange structure characteristics ,its injection mold is designed and the maneuvering tread demolding way is applied to get out flang tread .When designing demolding parts, hydraulic pressure motor and chain-gear mechanism are used. Besides, parting plane and the forming parts can be gained automatically in Pro/E(Pro/Engineer Wildfire3.0)and standard moldbase ca...

OBJECTIVE To assess the efficacy of a combination of Frank's mold therapy with intercourse as a treatment for congenital vaginal aplasia. STUDY DESIGN From 1973-1993, thirty-three patients with congenital aplasia of vagina and uterus were seen by one gynecologist. Patients with a partner were instructed how to create a functional vagina by a modified form of coitus ('interfemoral intercourse'...

BACKGROUND AND AIM OF THE STUDY The finite element method (FEM) has frequently been used to investigate the behavior of the aortic valve, but studies on the performance and behavior of free-hand autologous pericardial aortic valves reconstructed using specially designed valve molds have not been performed. The study aim was to demonstrate the effectiveness of a three-dimensional (3-D) cusp of t...

Mold contamination is a growing concern for homeowners in terms of both physical health and insurance. Health experts, although they concede that exposure to mold can cause respiratory illnesses, are calling for further research into other mold-related health effects and for development of standards for mold sampling and data analysis. The insurance industry is grappling with how---and whether-...

The use of genetically resistant cultivars is the best method to reduce losses caused by white mold (Sclerotinia sclerotiorum (Lib.) de Bary). As the best known resistance sources are not adapted, the genetic control of white mold in the common bean must be understood to guide breeding more efficiently. The objective of the present study was to identify the genetic control of the resistance of ...

Design revisions are expensive and time consuming. Yet, these are inevitable because product designers have limited knowledge about casting processes and have no means to evaluate the influence of design features on castability (costs, quality and productivity). Problems appear much later, at the tooling or manufacturing stage, when it is much more expensive to incorporate changes than at the d...

This paper presents the solutions adopted for a robotic polishing cell for mold manufacturing. Mold finishing is frequently carried out manually; these kinds of operations are iterative, time consuming and require experience. Automation can introduce cost reduction minimizing production times on such manual finishing operations. The research shown in this paper provides an overall solution with...

An experimental study was performed with the aim of developing a technique for manufacturing composite parts for use in dynamic robotic applications in lieu of heavy and expensive metal parts used in conventional robotic systems. There is already a wide usage of sandwich board materials in load bearing applications, but these do not provide equal strength in all directions, particularly compres...
