Principles of operation of numerically-controlled systems for manufacturing. Application of CAD/CAM systems and graphics N/C in programming.

Prerequisites & Corequisites: Prerequisites: IME 2540 and IME 2460.

Credits: 3 hours

Lecture Hours - Laboratory Hours: (2 to 3)

1. Machining Fundamentals including machine feeds and speeds - IME 2540
2. Understanding of capabilities of Graphical Computer Systems - IME 2460
3. Capability to define and follow an algorithmic approach to problem solving - CS 1040 or CS 1110

By the end of the semester the students should have the ability to:

1. Identify the major and secondary axes on Computer Numerically Controlled (CNC)
   machines. (a, b, & f).
2. Program CNC machines using EIA/ISO (G- and M-code) programming procedures (a, b, c, d, f, & h).
3. Operate graphical CAM systems to generate, simulate and verify EIA/ISO CNC programs (a, b, c, d, f, g, & h).
4. Modify CAM systems to tailor the post-processor for unique CNC machines (a, b, c, d, f, g, & h).

Objective 1

Mid-term Exam. The mid-term exam will be given on the last week of October. It will be comprehensive, covering all material that was presented in the lecture and the laboratory to date. The mid-term exam will account for 25% of the grade. (1, 2, 3, and 4).

Objective 2

Final Exam. The final exam will be held on the third week (14-18) of December. The final exam will be comprehensive, covering all material that was presented in the lecture and the laboratory for the entire semester. The final exam will account for 25% of the grade. (1, 2, 3, and 4).

Objective 3

Homework/pop quizzes: Various homework assignments will be made during the course of the semester. Homework will not be accepted late and must be submitted using WebCT-Vista. Pop quizzes will not be announced and can not be made up if missed. The total of all homework and pop quizzes will account for 5% of the grade. (1, 2, 3, and 4)

Objective 4

Class Participation: All students are expected to actively participate in the discussion of the topic of the day. The students will be evaluated on their individual degree of participation. This will account for 5% of the grade. (1, 2, 3, and 4).

Objective 5

Lab Activities: Various means will be used to evaluate the students lab work including (but not limited to) lab reports, lab quizzes, questioning about details of lab set-ups, etc. The evaluation of the lab activities will account for 35% of the grade. (1, 2, 3, and 4)

(Note: Due the arrangement of the labs work, missing more than one or two labs may lead to discharge from the course)

Objective 6

Lab Housekeeping: The maintenance of a clean and safe work area is vital to the manufacturing enterprise. All students will be required to clean up after themselves. Furthermore, every student will be required to determine and accomplish a necessary item of common housekeeping at each lab session. Evaluation of the student's housekeeping will account for 5% of the grade.
