Machining Fixtures

The design of machining fixtures for aeronautical parts is strongly based in the knowledge of the fixture designer, and it comprises certain repetitive tasks. An analysis of the design process allows us to state its suitability for developing Knowledge Based Engineering (KBE) applications in order to capture the knowledge, and to systematize and automate the designs.This work justifies the importance of fixtures for High Speed Milling (HSM), and explains the development of a KBE application to automate the design and manufacturing of such elements. The application is the outcome of a project carried out in collaboration with the company EADS.In the development process, a specific methodology was used in order to represent the knowledge in a semi-structured way and to document the information needed to define the system. The developed KBE application is independent of the parts design system. This makes it necessary to use an interface to input the part geometry into the KBE application, where it is analyzed in order to extract the relevant information for the fixture design process. The results obtained from the application come in three different ways: raw material drawings, fixture 3D solid models, and text files (Bill Of Materials – BOM, and Numerical Control – NC programs). All the results are exported to other applications for use in other tasks. The designer interacts with the application through an ad hoc interface, where he is asked to select or input some data and where the results are also visualized. The prototype KBE application has been carried out in the ICAD development environment and the main interface is with the CAD/CAM system CATIA V4.

AbstractThe wearable electronics integrated with textile-based devices is a promising strategy to meet the requirements of human comfort as well as electrical performances. This research presents a design and development framework for a seamless glove sensor system using digital knitting fabrication. Based on the performance requirements of glove sensors for controlling a prosthetic hand, desirable design components include electrical conductivity, comfort, formfit, electrical sensitivity, and customizable design. These attributes are determined and achieved by applying appropriate materials and fabrication technologies. In this study, a digital knitting CAD/CAM system is utilized to meet the desired performance criteria, and two prototypes of the seamless glove sensor systems are successfully developed for the detection of both human and robotic finger motions. This digital knitting system will provide considerable potential for customized design development as well as a sustainable production process. This structured, systematic approach could be adapted in the future development of wearable electronic textile systems.

Runner Design

The runner design is an important parts in plastic molding design. Its shape and dimensions have special effects on the molten plastic’s pressure, hot loss, injection speed, etc. At present, trapezoidal runner is used widely for better fluidity and lower assembly precision relatively compared with the circular runner. This paper uses the Fminsearch function of MATLAB and constructs an objective function based on the minimum length of the perimeter of the trapezoidal runner to optimize the trapezoidal runner section. The conclusion of this paper is that the perimeter of the trapezoidal runner is the shortest one when a equals c (shown as Fig.1), as well as the obtuse angle between a and c equals 120o. At this conditions, the volume of the molten plastic that flows through the runner section is maximum when the trapezoidal runner section area is given. The optimization results in the plastic mould design can used as the size or the constraints to drive the runner section in 3D CAD/CAM software, which can help the designer to get the trapezoidal runner section easily and quickly.

With the accomplishment of new engineering science and technologies, machineries formulated by the the technocrats are utilized in medical field. Biomedical Engineering has thus gained a prominent status in the recent years. Few decades ago, it was considered as weird thing if any mechanical engineers performed studies on dental area, but in today’s scenario mechanical engineers are doing studies as well as research in the area of dental science. In this paper an attempt has been made to select best crown material for molar tooth, So that an appropriate material can be placed in the human body which is most difficult task .so for designing a molar crown, modeling is done in pro/engineer software, it is one of the parametric 3D CAD/CAM/CAE solution widely used by mechanical engineers for designing any product .this software creates a complete 3D Digital model of the product. For this extensive research, design for all crowns will be the same but only material properties will be different. After design, failure analysis is done. Loss of ability to function normally is the study of failure analysis. This is accomplished by considering various loading conditions .Here finite element analysis is used, the standard principle underlying the FEM are simple. The word finite is used to describe the limited, or finite, number of degrees of freedom used to model the behavior of each element, the element are assumed to be connected to one another but only at interconnected joints, known as nodes. Considering a body through which the distribution of a field variable I.e. displacement or stress is required, this body could be subjected to various loads. Problem is solved by two methods: static fatigue and dynamic fatigue

Product And Process

Since the concept of integrated product development environment (IPDE) was introduced from the US Department of Defense, the Korean navy has made efforts to apply the concept to its naval design and production. Recently, the Korean navy has supported a project for naval shipbuilding to achieve the advanced defense acquisition program. This project focuses on the integration of naval shipbuilding information. The Product Model Management System (PMMS) for Korean naval acquisition was a partial result of the project. The architecture of PMMS and the product structure of a naval ship are proposed in this paper. Also, the data acquisition process among acquisition program administration offices and contractors is defined for the construction of three-dimensional naval ship product models in PMMS. By constructing the product model on previous Korean naval ships, the PMMS was confirmed to a suitable innovative acquisition strategy. PMMS is on the leading edge of new product and process innovations in the Korean naval shipbuilding.

Architecture, engineering, and construction industries maintain a long standing desire to enhance design communication through various forms of 3D CAD modeling. In spite the introduction of Building Information Modeling (BIM), designers and builders expect varying amounts of communication loss once construction has started due to indirect construction techniques or hand based methods to manufacture buildings. This is especially true for houses and small structures, buildings that makeup the core of villages and suburbs. Unfortunately, paper documentation and reading 3D CAD models on screen continue the trend of indirect production defined in most manufacturing industries as error. The emerging application of CAD/CAM within design and construction industries provides hope for elevated communication between design and building. With CAD/CAM, it is possible to manufacture buildings of all types and sizes directly from CAD files similar to mass produced artifacts, thus reducing complexity in communication between parties. This chapter is presentation of one process of direct manufacturing from CAD and the emerging possibilities for small building production using digital fabrication. The chapter will focus on houses to illustrate the potential of direct manufacturing of buildings from CAD data.

In spite of the importance of the globe as an educational and cultural tool, for visually impaired users, common globes are just spherical objects. Although there are commercially available globes for visually impaired users, globes that have convex and concave features on the surface denoting coastlines and country borders, most of them are expensive because they are made by hand. Consequently, visually impaired users wishing to purchase globes have a very limited range of choices. In terms of industrial production, producing globes with convex and concave surfaces essentially involves machining a spherical surface. For instance, with common machine tools, even positioning or marking a spherical surface of a certain size is very difficult operation since the posture of the tool must change dramatically. The purpose of the study is to develop a CAM system to design the surface of tactile globes suitable for individual needs and to manufacture them for the visually impaired at low cost and with a short lead time. In the report, as the first step, a method of holding the sphere and marking it via 3D-CAD/CAM technology and the control technology of an industrial robot is proposed. As a result, the system enables the marking of the coastlines and country borders on spheres automatically using our own CAM system and an industrial robot.
