Land Acknowledgement

First Nations peoples have lived on this part of Turtle Island for millennia, stewarding the land, the water and all that contributes to life in this region. Today, the culture and presence of First Nations, Inuit and Metis peoples enrich the lands and people of this territory.

Over two centuries ago, the Mississauga people welcomed settlers to this territory, providing sustenance and engaging in trade and commerce. Between 1781 to 1820, eight treaties were signed with the Mississaugas of the Credit First Nation who opened their territory to settlement. Today, Sheridan campuses are located on Treaty 14, also known as the Head of the Lake Purchase of 1806 and Treaty 22 and 23 of 1820.

Treaty history is foundational, and it is our collective responsibility to honour the land, as we honour and respect those who have gone before us, those who are here and those who have yet to come. We are grateful for the opportunity to be learning, working and thriving on this land, and we commit to learn the truth and be active in the process of reconciliation.

Section II: Course Details

Detailed Description
Students learn to prepare and write Computerized Numerical Control Manual Part Programs. They apply: Linear Interpolation, Circular Interpolation, Canned Cycles, Cutter Radius Compensation and Sub-Routine Programming to successfully write programs for both two axes turning centers and three axes machining centers.

Program Context

 
Mech Tech - Tool and Die Maker Program Coordinator(s): Chris Doucette
This required program core course is an introductory course in Computer Numerical Control (CNC). The student will apply all the skills learned in the practical and theoretical elements of the program to this topic. This knowledge will be used and built upon in CNC computerized programming. The skills gained within this course are applicable to all the precision metal cutting trades including Tool & Die Maker General Machinist, Mould Maker, Patternmaker and Machine tool Builder and integrator.

Mechan. Technician Tool Making Program Coordinator(s): Chris Doucette
Same as above.


Course Critical Performance and Learning Outcomes

  Critical Performance:
By the end of this course, students will have demonstrated the ability to understand CNC manual part programming.
 
Learning Outcomes:

To achieve the critical performance, students will have demonstrated the ability to:

  1. Interpret part drawings to develop an efficient manufacturing process.
  2. Apply C.N.C. programming language to actuate appropriate machine tool movements required for part manufacture.
  3. Manually write efficient C.N.C. programs to manufacture parts within required specifications.
  4. Describe the set-up of a 2 Axis Turning Centre using appropriate tooling, measurement and registration of tool offsets.
  5. Describe the set-up of a 3 Axis machining Centre using appropriate tooling, measurement and registration of tool and work piece offsets.
  6. Interpret and describe all machine programming features as required (e.g. edit, insert, alter and delete).
  7. Recognize and avoid tool crashes in C.N.C. programs.
  8. Debug a C.N.C. program.
