MFT 149 - Fundamentals of Computer Controlled Machining Credits: 3 1 Lecture Hours 4 Lab Hours
Prerequisites: MFT 143 , MFT 145
Description This course is designed to develop the skills of a machinist through knowledge of computer numerical control (CNC) production techniques. Students will be taught manual part programming in G and M code and conversational programming. Emphasis will be placed on writing part programs for lathe and milling machines. Learning Outcomes Upon successful completion of the course, the student will:
- Recognize and utilize safe work techniques.
- Identify parts, operations and applications of the CNC turning and machining centers.
- List advantages and disadvantages of CNC machining.
- Use right angle trigonometry to calculate tool position.
- Calculate speed and feeds.
- Use G and M code to write a program for CNC milling machines and turning centers.
- Perform canned cycles for hole operations.
- Perform conversational programming formats.
- Demonstrate appropriate setup for given operation.
