Recommended: MFG 144 or equivalent experience.

CAD/CAM course for quality control personnel, auditors, and inspectors uses MASTERCAM software to create part geometry and assign tool path to geometry. Topics covered include automatic generation and communication of CNC programs to machine tools in Oakton’s Manufacturing Lab, using post-processor translator. Both 2-D and 3-D tool paths used to make parts using machines with various controllers. Graphic simulation used to prove-out results.

Upon completion of the course the student will be able to:

1. Demonstrate an understanding of the principles of computer assisted NC Programming.
2. Write, enter, and debug programs.
3. Post-process source programs to usable CNC code.
4. Identify tooling and fixturing problems in NC>CNC machining.
5. Design or select tooling to solve manufacturing problems.

Students and employees at Oakton Community College are required to demonstrate academic integrity and follow Oakton's Code of Academic Conduct. This code prohibits:

• cheating,
• plagiarism (turning in work not written by you, or lacking proper citation),
• falsification and fabrication (lying or distorting the truth),
• helping others to cheat,
• unauthorized changes on official documents,
• pretending to be someone else or having someone else pretend to be you,
• making or accepting bribes, special favors, or threats, and
• any other behavior that violates academic integrity.

There are serious consequences to violations of the academic integrity policy. Oakton's policies and procedures provide students a fair hearing if a complaint is made against you. If you are found to have violated the policy, the minimum penalty is failure on the assignment and, a disciplinary record will be established and kept on file in the office of the Vice President for Student Affairs for a period of 3 years.
Details of the Code of Academic Conduct can be found in the Student Handbook.
