Subject Title
CNC Set-up

Subject Description
This professional development subject provides students with the skills and knowledge to perform basic set-ups on 3 axis computer numerically controlled (CNC) milling machines. Students have hands on training in setting up different jobs on 3 axis CNC milling machines with HAAS and Fanuc controls. They have opportunities to work with different cutting tools, instruments, jigs and fixtures required for basic 3 axis CNC setup.

Credit Status
One credit

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Observe accepted safety practices and procedures when working with or around CNC equipment.

2. Apply the Cartesian Coordinate System as it relates to a vertical CNC machining centre.

3. Secure and locate work piece material to machine table using a variety of clamping devices including strap clamps, and fixtures.

4. Select and identify cutting tools for milling operations.

5. Establish work position relative to machine home position.

6. Determine and load tool offset values using manual data input.

7. Calculate speeds and feeds.

8. Perform linear measurement using a variety of measuring devices including vernier callipers and micrometers.

9. Prove programs by performing a dry-run and single block.

10. Load programs into machine controller using RS232

11. Develop job setup and tooling sheets.

Modes of Evaluation

  • Assignments are due at the beginning of the class on which they are due.
  • A late penalty of 10% per day is assessed for late assignments, including those not handed in at the beginning of class when due.
  • Material will not be accepted after one week following the due date and/or when the marked material is returned to students, whichever comes first.
  • Assignments are to be prepared by computer.

Absenteeism and Exams
  • Students should be aware that absenteeism almost guarantees an inability to achieve satisfactory grades.
  • Students who are absent for an examination due to an emergency (e.g., motor vehicle accident, hospitalization or death in the family) may provide official documentation within five days of the missed exam and be provided a deferred exam at a later date.  Official documentation includes a death notice or an original doctor’s certificate identifying the date, length of time expected absence and the specific reason for the absence.  Examinations missed without official documentation and approval result in a grade of zero.
  • There are no deferred options for missed tests.  The value of missed tests, at the discretion of the Faculty, will be added to other evaluation components

English Proficiency
  • All written work should demonstrate the following characteristics for clarity and conciseness:
-writing is consistent with the rules of English grammar
-spelling and punctuation are correct
-sentences are structured correctly
-main ideas are supported with specific, relevant examples and reasons
-work flows logically through supporting statements/paragraphs
-work is arranged in correct format (e.g., as a report, essay)
-up to 10% of the final grade may be deducted on all work if the above English competencies are not met.

Format for Assignments
  • Students must use the standard, APA style for quoting sources.   Help is available at:

Laboratory Attendance
The laboratory component is essential and therefore it is strongly recommended  that you attend all labs.  Any missed labs must be supported with a legal document with three days of the lab.  Any student who fails to attend 2 scheduled laboratory classes for a 7 week subject and more than 3 laboratory classes for a 14 week subject will not pass the subject.    

Laboratory Safety
Students are required to review and understand the safety procedures and guidelines outlined on the first class and sign the sheet to this effect before beginning work in the laboratory.  Students must also wear a lab coat and safety glasses when conducting experiments.
A student who arrives without the proper safety equipment will not be permitted to participant in the lab but will be asked to leave the class.  The student will receive no grade for the lab missed.

  •     Tests, Exams, Participation                                                                        

Grading is based on the following marking scheme:
Machine Safety Test  20%
Midterm Exam  15%
Final Exam 30%
Practical Exam 35%

Other Evaluation Considerations
The student is expected to comply with the Safety Rules for working in the laboratory, sign the safety contract, and WILL NOT UNDER ANY CIRCUMSTANCES WEAR CONTACT LENSES in the laboratory.  The student will know where all safety equipment is located in the laboratory and will be familiar with WHMIS concepts and signage.
