Course Description
This course covers the fundamental manufacturing techniques using typical machine shop equipment. Topics include: safety, the selection, care, and use of hand and precision measuring tools and the selection of materials. Students will demonstrate competency in the safe and accurate use of machine tools including metal saws, drill press, lathe, and milling machines to produce individual projects safely and within tolerance specifications. The course introduces computerized numerical control (CNC) and fusion welding processes (GMAW, SMAW, TGAW ).
Core Course Performance Objectives (CCPOs)
- Demonstrate the correct and accurate use of typical mechanical engineering metrology equipment. (CCC 6; PGC 1)
- Demonstrate the safe use of machine shop equipment, in particular the mill and lathe, to produce accurate projects with different materials (Ferrous, Non-Ferrous and Plastic). (CCC 6; PGC 1)
- Examine basic CNC programming and machining process (CCC 2, 6; PGC 1)
- Perform basic fusion welding process: Stick, MIG and TIG. (CCC 2, 6; PGC 1, 5)
- Describe the classification, properties, and uses of common metals. (CCC 1, 2, 6; PGC 1)
- Demonstrate machine, hand tool, and general shop safety. (CCC 2, 3; PGC 1, 5)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.
