A course stressing the fundamentals of computer aided manufacturing and design. Emphasis is placed on CNC manufacturing, part sketching, geometric construction, layout procedures, and basic dimensioning procedures.

The course will progress from simple basic drawings to more complex and sophisticated drawings used to generate CNC programs for the HAAS Mills and HAAS CNC Lathe.

Technical drawing has been an integral part of industry for many years. It is a link between design and manufacturing and construction. Information is quickly communicated to construction and manufacturing companies in the form of drawings prepared to prescribed drafting standards. It is said that a picture is worth a thousand words. Actually, a drawing is worth much more. The speed of graphic comprehension can approach a rate of 50,000 times that of reading. Human beings have always sought the use of tools to make life easier and to enable them to become more productive.

• Online CAM Instructor Mastercam 2024 Courses: Mill 2D, 3D, 4 and 5 Axis, and the Lathe Course
• All books and handouts from CCET 3680 as a reference

• Create complete complex drawings using Mastercam 2024 software.
• Perform basic dimensioning.
• Mill complex parts using the Haas CNC mill.
• Design and manufacture at least one 3-D design culminated by machining it on the mill and lathe.
• Perform precision and semi-precision measurements.
• Apply personal and industrial safety standards.
• Perform appropriate measuring and testing of each manufacturing process.
• Design projects for manufacturing using CAD.
• Perform the necessary steps in the manufacture of each of the projects.
• Perform Geometric Dimensional Tolerance (GD&T) evaluation and develop a manufacturing quality report on all projects.
• Safely use the manufacturing processes required for each project.
• Calculate the proper feeds and speeds for a variety of cutting tools and materials.
• Understand and use the Machinery’s Handbook to find specific requirements needed to complete all manufacturing processes.
• Follow a production plan of all manufacturing operations required in the manufacturing of the many projects.

Assigned Drawings

Out of class time will be required to complete all of the assigned drawings. All assignments will include:

1. Mastercam drawing including tool paths
2. A simulated CNC program
3. Part run on the applicable CNC machine
4. Picture of the cut part
5. Quality report of the actual cut dimensions

All of these assignments will be submitted through Canvas.

Assignment Evaluation

• Drawings: 7 points
• Tool paths: 7 points
• CNC programs: 3 points
• CNC simulation: 3 points
• Run in metal or wax part (includes a picture): 30 points
• Total: 50 points

Midterm (100 points)

The midterm exam will be an in-class exam consisting of a drawing and/or part/project that is in alignment with the expected class skill level at mid-semester. The date will be announced.

Final (100 points)

The final exam will be an industry-level project consisting of a drawing and tool paths which are typical of projects needed in today’s world of manufacturing. All final projects must be approved before student work begins. Students may have the opportunity to volunteer to design items for local industry either by themselves or in groups.

Final project will be graded as follows:

• Design: 10 points
• Mastercam drawings: 10 points
• CAM tool paths: 10 points
• Set up on the machines to make whole part complete: 10 points
• CNC Program: 20 points
• Parts Run: 40 points

One project may be shared among up to 4 students as long as each student does his share of the work and the work is on time. There must be at least one part per student in the assembly of the final project.

Assessment Breakdown

• Assignments: 20%
• Final Test: 20%
• Quizzes: 20%
• Portfolio: 20%
• Final Project: 20%

Grading Scale

• 90–100% = A
• 80–89% = B
• 70–79% = C
• 60–69% = D
• 0–59% = F
• Not attending class = UW

Class Participation and Materials

Students are required to bring safety glasses, calipers, textbooks, and all other materials to each class meeting.

The instructor reserves the right to substitute and add drawings each day if needed.

All work is due before the next class period after the assigned date.

LATE WORK WILL NOT BE ACCEPTED FOR FULL CREDIT.

Final exam policy: Do not ask to take the final exam early. There will be NO make-up if a student misses the final exam. If a student does not take the final exam at the scheduled date and time, a grade of “F” will be assigned for the course grade regardless of the student’s attendance and class performance.

Safety and Professional Behavior

Projects will involve the use of lab or other university equipment. Students will maintain professional behavior at all times, particularly when operating equipment. Students are required to read and follow instructions for use of equipment and to use the equipment in a safe manner to minimize danger to themselves and others.

Disregarding safety and/or other procedures will result in dismissal from the lab area and a grade of zero for the associated project (at a minimum).

If you are unsure as to how to operate any of the equipment in a safe manner, ask for help.

Attendance is mandatory for passing this course. On time attendance is a must! Two lates equal an absence, four absences equal a failure.

If a student decides to withdraw from the course at any time, it is the STUDENT’S responsibility, NOT the instructor’s responsibility, to officially withdraw from the course. Each student should strive to accomplish all assigned work in a timely, competent, and complete manner throughout the semester.

Roll will be taken; if you miss a day, you are responsible to complete all work and assignments to receive credit for the work due that day.
