Efficiency in using plastic injection technology, especially within small to medium enterprises, is a very difficult target to achieve.  One of the contributing factor to the high cost of  using this technology is the trial and error nature of constructing the plastic mold which directly affect machninig cost and longet production cycle time.  The trial and error scheme can be significantly reduced and even eliminated with the application of concurrent engineering method supported by virtual prototype based CAD <em>(computer aided design)</em> and CAE <em>(computer aided engineering).</em>  Virtual prototype technology gives way to product analysis, design and material optimization, and proses parameter optimization prior to implementing the manufacturing process.  Therefore, we can anticipate all potential manufacturing flaws during the design process.  It is then expeceted to reduce machning and production process cost, increase product quality to boost up Company’s competitive advantage.

To save time and resources, many are making the transition to developing their ideas virtually. Computer-aided gear production realization is becoming more and more desired in the industry. To produce gears with custom qualities, such as material, weight and shape, the trial and error approach has yielded the best results. However, trial and error is costly and time consuming. The computer-aided integrated design and manufacturing approach is intended to resolve these drawbacks. A simple one stage reduction spur gearbox is used as an example in a case study. First, the gear geometry is developed using computer aided design (CAD) modeling. Next, using MATLAB/Simulink, the gear assembly is connected virtually to other subsystems for system expectations and interaction analysis. Finally, using finite element analysis (FEA) tools such as ABAQUS, a dynamic FEA of the gear integration is completed to analyze the stress concentrations and gear tooth failures. Through this method of virtual gear design, customized dimensions and specifications of gears for satisfying system-level requirements can be developed, thereby saving time and manufacturing costs for any custom gear design request.

In modern industrial production some of the major factors of successful development include: cost reduction of the production, im-provement of its quality, as well as help to minimise the time in market en-try. Computer-aided design and Computer-aided engineering (CAD / CAE - systems) are the most effective for implementation of these requirements. Possible use of this engineering modeling simulation in conjunction with the power and speed of high performance computing could reduce costs and time of each cycle of designing, and also significantly reduce devel-opment time. The introduction of new technologies, the use of high quality products and engagement of qualified personnel would allow businesses and organizations to get on a path of innovative development of design and production systems.

Current UTeMs fire fighting machine is developed to operate indoor only. It is not efficient when it is operating on rocky surfaces (outdoor) as it faces the problem of shock and vibration reduction. The track system of the machine cannot move smoothly because the rollers are fixed to the chassis. This paper describes the method of up-scaling and optimising the track system for the current fire fighting machine. The new track system concept is firstly developed by using Computer-Aided Design (CAD) and Computer Aided Engineering (CAE) software. Subsequently a prototype is built to validate the functionality of the new track system which is more efficient in absorbing the vibration and shock. Analysis and optimisation of the prototype is performed using CAD method with the CATIA V5 R16 software.

Success of the design process hinges on efficient communication between the various functions involved. Traditionally this communication has been ‘paper based’ with information passing between sales, design, production and manufacture to describe the complete history of the product. This complex interaction between the functions depends on the availability at each stage of the most up-to-date and accurate information. The paper based system has many shortcomings in this respect particularly the inability of the designer to assess interactively the effect of any changes he may make on the cost, delivery, quality and performance of the product. The use of computer aided design as a central part of the computer aided engineering system allows a company greatly to improve communications during a project by giving the engineer a way of providing accurate information more quickly to each adjacent function while receiving feedback on the effectiveness and suitability of the product in a fraction of the time.

The long-standing goal of computer aided design (CAD)/computer aided engineering (CAE) integration demands seamless interfaces between geometric design and engineering analysis/simulation tasks. The key challenge to this integration stems from the distinct and often incompatible roles geometric representations play, respectively, in design and analysis. This paper critically examines and compares known mesh-based and meshfree approaches to CAD/CAE integration, focusing on the basic tasks and components required for building fully integrated engineering applications. For each task, we identify the fundamental requirements and challenges and discuss how they may be met by known techniques and proposed solutions.

Computer-Aided Engineering (CAE) is a course that is required during the third year in the mechanical engineering curriculum at Binghamton University. The primary objective of the course is to educate students in the procedures of computer-aided engineering design. The solid modeling and analysis program Pro/Engineer™ (PTC®) is used as the basis of this course. As a means to this objective, students must be trained to use the Pro/Engineer™ software. We created a series of video lectures using Camtasia Studio (TechSmith®) to accomplish the Pro/Engineer™ training. As the literature for the software says: “Camtasia Studio is a complete solution for quickly creating professional-looking videos of your PC desktop activity.” Thirteen videos were created for this course, which incorporated audio combined with PowerPoint™ slides. The video files (avi's) are distributed to students on five CD's. This article describes the structure of the course and how the videos are integrated into it. Also included is a brief overview of the creation of the videos. Results of a survey of student satisfaction with the video format that was used in the course are presented.

This paper addresses the importance of integrating Computer Aided Engineering (CAE) software and applications in the mechanical engineering curriculum. Computer aided engineering tools described include Computer-Aided Design, Computer-Aided Manufacturing, and Computer-Aided Analysis tools such as finite element (FE) modeling and analysis. The integration of CAE software tools in the curriculum is important for three primary reasons: it helps students understand fundamental engineering principles by providing an interactive and visual representation of concepts, it provides students an opportunity to explore their creative ideas and designs while keeping prototyping costs to a minimum, and it teaches students the valuable skill of more efficiently designing, manufacturing and analyzing their products with current technology making them more marketable for their future engineering careers. While CAE has been used in the classroom for decades, the mechanical engineering program at the University of North Florida is making an aggressive effort in preparing the future engineering workforce through computer-aided project-centered education. The CAE component of this effort includes using CAE software when teaching stress, strain, dynamics, kinematics, vibrations, finite element modeling and analysis, design and design for manufacturing, manufacturing and technical communication concepts. This paper describes CAE projects undertaken in several of the mechanical engineering courses at UNF in an effort to share creative teaching techniques for others to emulate.
