MTTC 107 - CNC Setup and Operations I
PREREQUISITES/COREQUISITE: MTTC 101 - Introduction to Machining .
PROGRAM: Machine Tool Technology
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019
Introduces and instructs the student in all aspects of Computer Numeric Control (CNC) machine operation and setup. The student will set up and operate CNC mills and lathes utilizing set-up, production, in-process inspection, and preventive maintenance methods similar to what the student may experience in the present day work environment. This course prepares students to take the NIMS Level I CNC operations certification.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Demonstrate knowledge of basic OSHA requirements, general shop safety, and MSDS information. (i)
- Create and interpret documentation for safety, set-up, and quality control purposes. (b)
- Utilize standard shop documents such as Job Routers, Job Process Sheets, Inspection Plans, etc. (b)
- Effectively interpret part prints or technical drawings, including GD&T, and use the information to select proper gauging and measurement tools. (b)
- Demonstrates knowledge of primary mill and lathe components. (a)
- Correctly perform preventative maintenance checks on the CNC lathe and mill. (i)
- Demonstrate correct response to CNC malfunctions and taking appropriate steps to recover the machine. (i)
- Interpret CNC programs to determine units of measure, positioning system, tools, spindle speeds, feed rates, canned cycles, coolant use, and axis movements. (b)
