Mechanical engineering graduates are expected to possess a working knowledge of modern Computer Aided Design/Computer Aided Manufacturing/Computer Aided Engineering (CAD/CAM/CAE) tools. The instructional challenge is to balance fundamentals with applications, and theory with practice. Many courses teach CAD from a mathematical base. This approach emphasizes "what do you know" evaluation without addressing "what can you do" expectations of both students and employers. This paper approaches instruction from a product centric perspective that, with each step, progressively builds skills and knowledge from mechanical dissection and solid modeling fundamentals towards original product design, prototyping, and testing. In first year, student teams dissect a product and produce solid model parts and assemblies. The upper year courses require product design to the prototype stage, with consideration of optimization and manufacturing issues. Incorporated subject material includes organizational behavior and team building, solid modeling theory, finite element analysis, CNC machining, rapid prototyping, and moldable part design. Implementation experiences in actual courses are described and discussed. Suggestions are provided for others contemplating similar initiatives. [ABSTRACT FROM AUTHOR]

The article presents information on tools that can help mechanical engineers avoid common pitfalls in designing complex mechatronic motion control systems. To help facilitate a more integrated design process for electromechanical systems, software developers are partnering with electrical and control design companies to add motion simulation capabilities to computer-aided design environments to create a more unified mechatronics workflow. Industrial motion software can simplify simulations such as calculating position versus time arrays for coordinated multi-axis motion trajectories. The concept called virtual machine prototyping brings together motion control software' and simulation tools to create a virtual model of an electromechanical machine in operation.

The article offers information on Penryn central processing unit (CPU), the latest CPU by Intel Corp. It states that the new manufacturing process will help the company in producing superfast desktop chips. It informs Penryn CPUs are built on a manufacturing process, that shrinks the features of the chip down to 45 nanometers. The Penryn CPUs are two dual-core CPUs paired on a single silicon package with a shared bus interface. It states that the first desktop Penryn chip, QX9650, is a quadcore CPU that can be used in high-end audio or video applications. A performance test of QX9650 Penryn chips reveals, that the speed of the new chip is faster than the earlier chip used by the company.
