Parametric Modeling, Rapid Prototyping and a Walker RobotAbstractComputer-aided-engineering tools, such as CAD, FEA and CAM, are becoming to be theessential tools to the engineering practices in industry. This paper describes the development ofan applied Parametric Modeling course that is being offered by the Mechanical andManufacturing Engineering Technology (MET) department at Oregon Institute of Technology(OIT) .Parametric Modeling technology is a new breed of Computer Aided Design (CAD) technology,which can be used to aid the creation of better Designs. The Parametric Modeling technologywas first introduced back in 1989; and with the developments of the other leading edgetechnologies, we now see very exciting changes in how an engineer perform his/her daily tasksin industry.In 1996, the MMET department began to incorporate the parametric modeling software in theME, MET and MFG programs. Last year, 2008, the MMET department purchased a RapidPrototyping (RP) machine. The combination of these new technologies has enabled our studentsto be much more creative and productive in doing design works.In the Winter term of 2009, an elective course (ME 475 Parametric Modeling) containing all theabove mentioned elements, was developed and offered. The course has been offered every yearsince 2009.The main emphases of the course are placed on both teaching the students to use a commerciallyavailable parametric package and to go through the complete design process. The students aregiven a specific design task; currently the design task has been to build a walker robot. Thecourse objectives have been established as follows:· To learn the basic concepts and procedures associated with using a commercially available Parametric Modeling package.· To understand and the use of 3D Printing and Rapid Prototyping technology .· To gain hands-on experience by going through a design process.· To learn and perform 2D and 3D kinemtaic analysis using modern computer software.· Apply the techniques and skills taught to related problems in follow-on courses.This paper describes the changes and results of the Applied Parametric Modeling course offeredby the Mechanical and Manufacturing Engineering Technology Department at Oregon Instituteof Technology.
