This paper presents simulation of multibody manufacturing systems with the support of numerical tools. The dynamic and cybernetic characteristics of driving system are discussed. Simple prototype models of robot arm and machine tool’s driving system are quickly established in Computer Aided Design (CAD) software inwhich the whole specification of material, inertia and so on are involved. The prototypes therefore are simulated in RecurDyn- a Computer Aided Engineering (CAE) software. The models are driven by controllers built in Matlab/Simulink via co-simulation. The results are suitable with theory and able to exploied for expansion of complexly effective factors. The research indicates that dynamic analysis and control could be done via numerical method instead of directly dynamic equation creation for multibody manufacturing systems.

This chapter presents the rapid prototyping and manufacturing concepts applied as means to reducing time between jewellery designs and manufacturing process. Different processes on jewellery modelling production are presented. Nowadays, the use of technologies as CAD/CAM - Computer Aided Design and Manufacturing in high production companies are very disseminated. However, the implementation of these resources at the design and manufacturing processes of jewels and fashion accessories, in small and medium size businesses, is still insipient. As reference, is presented the situation observed in small and medium companies located in Minas Gerais, Brazil.

: Acrylic resins are the most commonly used materials in prosthetics and orthodontics until now. They have a well-documented history of use as biomaterials in the manufacture of different types of dental appliances. The objective of this study was to describe the properties of acrylic resins and the processing methods used for these materials in dentistry. The review depicts the most important achievements in this area, indicating that the resin technology evolved in different directions. The mechanical and biological properties of acrylic resins were improved by the addition of mineral or natural fibers, and/or fillers including nanofillers, as well as by poly(methyl methacrylate) surface modification. The presence of residual monomer was reduced as a result of postpolymerization activity. New types of acrylic resins were developed for processing Computer-Aided Design/Computer-Aided Manufacturing systems and three-dimensional printing.

In the shipbuilding industry, it is relatively common knowledge that CAD/CAM (Computer Aided Design/ Computer Aided Manufacturing) systems can generate accurate and consistent drawings. These drawings can then be used for production support lofting, parts generation, reference material and so forth. However, one of the most significant advantages of utilizing a CAD/CAM system is not so commonly known: the development of a design database. While conventional computer systems generate, store and analyze numerical or textual databases or both, CAD/CAM systems generate, store and analyze data bases of graphics. This paper illustrates methods which optimize use of a graphic data base, focusing on the application of CAD/CAM analytical capabilities to mass properties analyses (as practiced in naval ship design). These methods are results of combining CAD/CAM technology with existing systems and knowledge to achieve cost-effective, technically superior, more accurate methods of performing engineering tasks. Accordingly, methodology, actual productivity comparisons and other related applications are presented.

Robotic manufacturing systems have provided improvements in productivity and quality in the automotive and semiconductor industries. Shipbuilding, however, is a one-of-a-kind manufacturing process and as such embodies a completely different set of problems than the mass production environment. The planning for robotics applications in shipbuilding must be done for each unique component and, therefore, must be done efficiently to achieve the benefits of automation. This will require a close relationship between computer-aided design (CAD), computer-aided manufacturing (CAM), computer-integrated manufacturing (CIM), and the manufacturing systems used on the waterfront. One of the major efforts to be performed is the integration of these processes through the timely presentation of information. One of the tools that can be used to integrate these processes is the Standard for the Exchange of Product Model Data (STEP). This paper will identify the relevant components of a STEP applications protocol (AP) for welding which can be applied to shipbuilding and outline the efforts required to bring it into existence.
