Catalog Description
Formerly known as WELD 66
Advisory: Completion of ADVM 62 with grade of "C" or better
Hours: 90 (36 lecture, 54 laboratory)
Description: Intermediate course making billet aluminum parts from start to finish using HAAS CNC milling machines. Fusion 360 will be used to model and program class assignments which are then posted to HAAS machines where students will learn how to set up and operate HAAS CNC vertical machining centers. After the parts have been machined, students will use common industry measuring and inspection techniques to insure their parts are in tolerance. (not transferable)
Course Student Learning Outcomes
- CSLO #1: Demonstrate safety standards for both a learning lab environment and worksite environment of a CNC Machine Shop lab.
- CSLO #2: Apply the terms used in this industry: X-Y-Z Axis, tool offsets, work offsets, linear interpolation motion, circular interpolation motion, cutter compensation, toolpath, and dryrun operation.
- CSLO #3: Use CNC machine for the the assigned project(s).

Articulation Information
Methods of Evaluation
- Objective Examinations
- Example: Students will take a multiple-choice test on each major topic area in CNC Mill application. Standard Grading. Example Question: The Z-direction is: a. left to right, right to left, b. forward backward, backward forward, c. up down or down up, d. none of the above.
- Projects
- Example: The instructor-assigned student projects are evaluated to industry standards through the use of performance rubrics. Example: Comparison of blueprint to finished project part.
- Skill Demonstrations
- Example: The instructor will use student skill demonstrations to evaluate student performance to industry standards as an entry level CNC operator. Example: Student will demonstrate work off-set on vertical mill.

No
Methods of Instruction
- Laboratory
- Lecture/Discussion
- Distance Learning
Lab:
- Instructor demonstrates how to set up the Haas milling machine, followed by the students safety demonstrating how to perform the set-up.
Lecture:
- Instructor lecture on fundamental technical sciences integrated with applied technical areas (such as engineering materials and mechanics), to successfully apply the analytical techniques (and problem-solving skills) needed. Student will distinguish production steps needed to program code to perform machine operations.
Distance Learning
- Following a brief intro video and reading assignment describing the difference between “climb milling” and “conventional milling”; the students shall discuss this subject in a discussion board both with the instructor and other students within the class.
Typical Out of Class Assignments
Reading Assignments
1. Students read the safety section from the text book and be prepared to discuss in class. 2. Students are required to read chapter on measurements and complete the review questions at the end of the chapter.
Writing, Problem Solving or Performance
1. Students will complete an assigned project that meets the criteria and specifications outlined. Example: Tighten 1M and 2M parts. 2. The student will track their project's time expenditures and materials in order to complete the job costing component requirement of this course.
