CAD/CAM and Robotics Applications in Laboratory-Learning Environment

چکیده
In this paper, how the design/automation hardware and software and manufacturing laboratory facilities are effectively integrated to teach Computer Aided Design (CAD), Computer Aided Manufacturing (CAM), CAD/CAM integration, and robotics with appropriate hands-on experiences in the Biomedical, Mechanical, and Industrial Engineering Programs are presented and discussed. A typical CAD module developed and taught in Biomedical Engineering includes the use of patient-specific 2D computerized tomography (CT) to generate 3D modeling and simulation of the ankle complex using finite element modeling (ANSYS 8.1) for determining the optimal meniscus thickness. Typical lab modules developed and taught in the Mechanical and Industrial Engineering Programs include: 1. The CAD/CAM module: involves designing a spline with 6, 8, or 12 grooves using AutoCAD or Pro-Engineer, making the spline on a CNC machining center using the rotary axis (XZ-plane), measuring certain dimensions of the part made, and making an error analysis; 2. The robot module: involves the use of a programmable five-axis robot (CRS A255) for a Kool-Aid mixing application consisting of designing and building a fixture to hold a cup for Kool-Aid mix, cup for sugar, bottle of water, a mixing cup, and a spoon. The robot arm should be programmed to include all the necessary motions to complete the mixing process. The results obtained from the student team projects on the above three modules are also presented, analyzed, and discussed.
