Attempts to include Computer-Aided Design and Computer-Assisted Learning facilities in a substantial way into undergraduate teaching lead inevitably to a consideration of appropriate (efficient) methods of instruction. A method based on syndication of tasks, used at Ulster Polytechnic, is described. The method has been found particularly useful in teaching System Dynamics and Control.

Restorative materials are experiencing an extensive upgrade thanks to the use of chairside Computer-aided design/computer-assisted manufacturing (CAD/CAM) restorations. Therefore, due to the variety offered in the market, choosing the best material could be puzzling for the practitioner. The clinical outcome of the restoration is influenced mainly by the material and its handling than by the fabrication process (i.e., CAD/CAM). Information on the restorative materials performances can be difficult to gather and compare. The aim of this article is to provide an overview of chairside CAD/CAM materials, their classification, and clinically relevant aspects that enable the reader to select the most appropriate material for predictable success.

Significant Attention

Modeling the human arm and calculation of the human arm reach are important for designing workspaces. An appropriate workspace design would reduce musculoskeletal disorders and wrist injuries in repetitive tasks. Among different human arm workspace designs and reach calculations, computer-based methods have recently attracted significant attention. This is because conventional experimental methods do not provide sufficient flexibility for interactive design modifications and integration of different aspects for workspace design. Despite advances in computer-aided design, many computer-based methods still rely on mock-ups and experimental set-ups. In this work, a computer-aided method is investigated for predicting the human arm reach. The kinematic modeling convention of Denavit-Hertenberg is adopted for formulating the reach. Simulation results are provided to demonstrate the effectiveness of the method. The methodology enables visualization of the reach volume of the human arm and could be easily adjusted for different human operators.

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.

Laboratory work is an important element in engineering training, which should correspond to up-to-date tendencies in computer-based technologies in design, production, maintenance and preserving mechanisms. Computer-based laboratory work consists of 16 assignments. Seven assignments are carried out on laboratory stands, the remainder are provided on PC, using programs like “Visual Structure Editor”, “DYNAMO”, “APM Win Machine”. The system Visual Structure Editor (VSE) is designed by specialists of “Machine Mechanics and Computer-Aided Design” department, of the Maritime State University named after adm.G.I.NEVELSKOY, Vladivostok, under the direction of prof. Valentina V. Kuzlyakina. The system APM (Automated Projecting of Mechanism) is designed by the research-and-production centre “APM” under the direction of prof.V.Shelofast, from the city of Korolyov, Moscow area. These systems are multifunctional. They allow project different mechanical systems at the stage of structural and parametrical synthesis, carry out strength calculations and design elements of machines and mechanisms. They are good in operation. Teachers and students easily master the systems. Laboratory works with computer support allow students to pass from a concrete object to modeling on a PC, and to solve complex engineering tasks during the education process.
