Subject Title
Mastercam Level II

Subject Description
This subject covers the more advanced features of the PC-based MasterCAM software. It includes a short review of 2D geometry creation before moving on to 3D surface modeling. Students assess the effectiveness of their work and program output using the built in verify functions.

Credit Status
One credit toward the Computer Numerical Control (CNC) Programming Recognition of Achievement

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

1. Program computer numerically controlled (CNC) milling machines using computer aided manufacturing (CAM) software.

2. Read and interpret NC files and codes generated by CAM software.

3. Select appropriate cutting and geometry creation planes.

4. Select and manipulate part geometry.

5. Translate and transform part geometry.

6. Generate toolpaths.

7. Create 3D surfaces.

8. Construct 3D geometry in a CAM software package.

9. Post-process toolpaths to create codes for CNC milling centres.

10. Simulate toolpath using verification software.

11. Interact with CAM software using the keyboard and menu structure.

Essential Employability Skills
Execute mathematical operations accurately.

Apply a systematic approach to solve problems.

Use a variety of thinking skills to anticipate and solve problems.

Locate, select, organize, and document information using appropriate technology and information systems.

Analyze, evaluate, and apply relevant information from a variety of sources.

Manage the use of time and other resources to complete projects.

Cheating and Plagiarism
Each student should be aware of the College's policy regarding Cheating and Plagiarism. Seneca's Academic Policy will be strictly enforced.

To support academic honesty at Seneca College, all work submitted by students may be reviewed for authenticity and originality, utilizing software tools and third party services.

Modes of Evaluation

  • Assignments must be submitted at the beginning of the class on the date 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 a final 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 or midterms.  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.  Contact lenses are not permitted.
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.

Term Tests, Final Exam

Grading is based on the following marking scheme:
Tests 70%
Final Exam  30%
