Catalog Description

Prerequisite: Completion of ADVM 0005D with a grade of "C" or better
Hours: 72 (18 lecture, 54 laboratory)
Description: Advanced applications of three-axis CNC surface contour machining. Students develop complex part geometry using Computer-Aided Design (CAD), import and process models in Computer-Aided Manufacturing (CAM) environments, and create machine code for 3-axis contour machining. Emphasis is placed on advanced workholding and fixture design, including the use of fixture clamps, locating devices, and modular fixturing systems for accurate and repeatable setups. Students plan machining operations, optimize toolpaths, and validate programs through simulation and verification. Projects culminate in the production of complex contoured components machined safely and accurately on 3-axis machining center. (not transferable)
