CLASS CODE: ENGRT 234 CREDITS:  3
DIVISION: PHYSICAL SCIENCE & ENGINEERING
DEPARTMENT: MECHANICAL ENGINEERING & TECHNOLOGY
GENERAL EDUCATION: This course does not fulfill a General Education requirement.

DESCRIPTION: Automated machine control through Computer-Aided Manufacturing (CAM) and Computer Numerical Control (CNC). Students gain practical laboratory experience on CAM, CNC, and manual programming on a variety of CNC equipment (machining center, lathe, and wire EDM). The principles of machining variables, tooling, and setups will be reviewed.
TAUGHT: Fall, Winter
CONTENT AND TOPICS: - Evolution of NC, CNC, and CAM
- Machining variables (lathe and mill)
- Specific G & M Codes, machine operation, and setups for the following machine tools:
- Haas Vertical Machining Center (Model VFO)
- Okuma 2 Axis Lathe (Model 5020)
- Sodick Wire EDM (Model )
-MasterCam programming on the three machine tools (lathe, mill, and wire EDM).
GOALS AND OBJECTIVES: The students will:
1. Understand and do manual/CNC G&M code programming on the Okuma lathe and HAAS VFO machining center.
2. Understand and do CAM programming with MasterCAM software.
3. Understand tool selection and sequencing for both lathe and mill.
4. Demonstrate and understand machining parameters (cutting, speed, feeds, and infeeds).
5. Evaluate tool selection and fixture design.

The above values are close approximations, not exact values.

Students are expected to attend all lectures and laboratory sessions. If it is necessary to be absent at any of these sessions the student should make pre-arrangements with the instructor. Particularly if a laboratory session is missed the student must check with the instructor before running any of the laboratory equipment. This is for the studentís personal safety as well as protecting the laboratory equipment from possible damage.

Policies: Students are expected to observe the RICKS COLLEGE Honor Code. This includes: conduct, dress and grooming standards, and observing LDS principles.

Extra credit projects can be arranged if approved by the instructor.
PREREQUISITES: ME 131 & 132, Math 110 & 111
