FAB2150 Cnc Turning

Intermediate · 1 credit · TMT - Trades, Manufacturing and Transportation

Description: Students develop skills in computer-assisted design (CAD) and computer numerical control (CNC) programming to manufacture a product on a CNC lathe.
Prerequisite: FAB1130: Principles of Machining
Parameters: Access to a fabrication work centre, complete with a CNC turning centre, and to instruction from an individual with specialized training in CNC practices.

Outcomes The student will:

1 take preventive measures to avoid accidents and personal injury to self and others by identifying safety hazards associated with CNC equipment
- 1.1 describe the safety features that are built into the CNC equipment
- 1.2 describe the:
  - 1.2.1 appropriate use of protective equipment and clothing
  - 1.2.2 need to keep the work area clean and free of hazards
  - 1.2.3 importance of following the manufacturer’s instructions and keeping all guards in place and in working order
- 1.3 describe a safety plan in case of an accident
2 demonstrate two-dimensional programming and/or CAD skills
- 2.1 identify the relationship of the x and y axis on a metal lathe
- 2.2 explain how to program a lathe using absolute coordinates
- 2.3 compare the advantages of using incremental and absolute systems of measurements
- 2.4 explain the difference between using a fixed zero and full floating zero
- 2.5 describe the purpose of G and M codes
- 2.6 explain how canned cycles are used in programming
- 2.7 explain how a CAD file can be converted to a machineable part file
3 apply CNC programming skills to manufacture a turned part
- 3.1 describe the principles of machining and the operation of a metal lathe
- 3.2 analyze a CNC lathe and describe how turning speeds and feed rates are controlled; tools and work pieces are mounted
- 3.3 identify the turning capabilities of a lathe; e.g., types of materials, set-ups, cutting tools
- 3.4 prepare a program from a print using absolute coordinates and/or produce a CAD design
- 3.5 simulate the tool path using computer graphics
- 3.6 load the program or convert a CAD file
- 3.7 identify reference and clearance points
- 3.8 mount and secure the work piece
- 3.9 mount and set cutting tool(s)
- 3.10 complete a test run
- 3.11 manufacture the part
- 3.12 inspect the part to see that it meets the print dimensions, tolerances and specifications
