COURSE CONTENT

Outcomes and Objectives:
At the conclusion of this course, the student should be able to:

Upon successful completion of this course, the student will be able to:

1. Practice the safe use of tools and machines.

2. Compare and contrast manual and CNC (computer numeric control) lathe operations.

3. Relate the theory of CNC lathe operation to machining processes.

4. Generate two-dimensional geometric images for CNC lathe projects using computer-aided drafting (CAD) software.

5. Using a drafted image, write and interpret code for machining a part on a CNC lathe.

6. Troubleshoot code for incorrectly machined parts.

7. Calculate cutting speeds and feed speeds for various computer numeric  control lathe operations.

8. Select appropriate tool bits for machining to CAD specifications.

9. Diagnose basic problems faced in the operation of the computer numeric control lathe.

10. Students who repeat the course will accomplish lathe machining processes utilizing the Master CAM (computer-aided machining) program, a more advanced and powerful computer-aided drafting and machining software that utilizes a post-processor to process code for machining.

Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 0%
None
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments and skill demonstrations are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 20 - 30%
Homework problems
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 30 - 45%
Performance exams, lab projects
Exams: All forms of formal testing, other than skill performance exams.		Exams 30 - 40%
Multiple choice, true/false, matching items, completion
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 0 - 0%
None
