: Introduction to the Computer Simulation of MetalForming Processes course is briefly discussed, followed by the course learning objectives andoutcomes. Also, the assessment and the evaluation tools developed for this course are presented.Finally, the applied research done on different aluminum alloys is outlined and discussed.As mentioned in the metal forming literature [1-5], the use of “soft tooling” has already gainedpopularity in the stamping industries compared to “hard tryouts”, not only because of the cost andbetter understanding of the science behind real forming, but also due to the availability of powerfulcomputational tools. The Virtual Metal Forming course has 4 credits with 4 to 6 contact hours andis currently offered at the mezzanine (500

The design criteria was that thefinished applet be able to run on a Pentium 1 100 MHz machine, which was judged to bethe slowest machine likely to be used by a student.

We believe that students’ enthusiasm for the course resultsfrom both the uniquely collaborative design of this class and the real world application of all ofthe material provided in this innovative course.1. IntroductionMany of today’s engineering graduates lack the necessary skills to become contributing membersin an industrial team environment immediately upon graduation. Most engineering schools haveconcentrated their efforts in preparing engineers to go to graduate school, or have simplyneglected the more practical aspects of the profession, preferring to let industry train theirengineers through co-op or on site training programs

Finally, they were asked to organize the software with an applicationprogrammer’s interface that would facilitate software development by the customer.Deliverables due at the end of the course were: 1) One prototype manipulator with documented tests to prove that it met specifications. 2) A complete set of software including source code and user documentation. 3) A presentation discussing the purpose, operation and specifications of the system. 4) A report describing

With the advent of real-time data acquisition and signal processing technology, it is nowmuch easier to develop instrumentation lab experiments for student use. The current hardware andsoftware enables our students to achieve highly accurate measurements, perform time domain andfrequency domain analysis, and store the data for subsequent use, analysis, and design. This paperdiscusses some of the methods developed for implementing these labs. We believe our techniqueshave greatly enhanced the ease of teaching and learning these important topics in instrumentation.1.

IntroductionThe goal of this simulation package is to actively engage students in the process of learning how aCPU works. Students who take a passive approach to learning are less likely to learn the materialand are less likely to perform well in their courses. By illustrating the flow of data within a CPU asit fetches, decodes, and executes instructions, this simulator will help students to learn the materialbetter.Most textbooks for computer organization and architecture have some type of simulatoravailable2,3,4.

Pulse widthmodulation is used to change the speed of motion. The motion control and digital I/O are onseparate connectors, so two cables and connector blocks are needed.
