Description: Multi-axis Computerized Numerical Control (CNC) machines have become the application of choice for complex sculptured surface machining. Simulation of tool paths and machine operations is desirable for cost and time savings. These advanced technologies are being integrated into a senior Manufacturing Engineering Technology (MNET) curriculum at the South Dakota State University (SDSU). Seven projects or exercises were assigned to students. A 4-axis HAAS machining center with Direct Numerical Control (DNC) capability was setup by students. 3D complex sculptured surface models were created from 2D drawings at different Z levels for turbine blades. CNC programs were generated for free-form surfaces and 4-axis parts via computer aided manufacturing (CAM) software. Feed-rates were optimized for more efficient machining and improved finish quality. Models of 3 and 4-axis machines in the manufacturing lab were created for simulation. CNC programs were verified by Vericut software prior to actual machining in the lab. Goals of these projects include: extend students knowledge in CNC machines, programming, simulation, verification and optimization; teach students how to model and machine the complex free-form surface; and foster students independent learning. This paper will describe the curricular module used in the course in detail and provide simulation demonstrations. Results of simulation and the production lab machining are shared.
