FAB2140 Precision Milling 1

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

Description: Students develop basic milling skills to shape and finish common machineable metals and plastics.
Prerequisite: FAB1130: Principles of Machining
Parameters: Access to a fabrication work centre, complete with a vertical and/or a horizontal mill and accessories, and to instruction from an individual with specialized training in machining practices.

Outcomes The student will:

1 take preventive measures to avoid accidents and personal injury to self and others by identifying health and safety hazards specific to milling operations
- 1.1 observe all safety procedures related to the use and operation of metal milling equipment
- 1.2 describe a safety plan in case of an accident
2 identify safe milling machine set-up, operation and shut-down procedures
- 2.1 research typical set-up procedures for horizontal and/or vertical milling to create flat surfaces, grooves and chamfers
- 2.2 compare the operation and uses of a vertical mill with the operation and uses of a horizontal mill
- 2.3 identify and describe the types of cutters used in vertical and horizontal milling according to their size, construction and purpose; e.g., plain milling, side milling, end milling cutters
- 2.4 use the recommended lubricants for a given milling machine
- 2.5 identify the purpose of a cutting fluid and identify common types
- 2.6 identify the factors that determine cutting speeds, feed rates and depths of cuts
- 2.7 explain the advantages and disadvantages of upcutting and climb milling
3 demonstrate basic milling machine skills and practices
- 3.1 identify and describe the basic parts and accessories of a milling machine
- 3.2 identify, from a machine drawing of a milled part, the:
  - 3.2.1 overall dimensions and tolerance
  - 3.2.2 quality of surface finish
  - 3.2.3 most appropriate milling machine and cutters to be used
- 3.3 list and describe the machining operations to square stock, bevel and chamfer surfaces
- 3.4 calculate the appropriate cutting speeds, feed rates and depth of cuts for a specific operation
- 3.5 demonstrate basic competencies using a milling machine to rough size, square, bevel, chamfer and finish machine parts to the prescribed tolerances and specification
- 3.6 research ways to improve output quality and machining time
4 demonstrate basic competencies
- 4.1 demonstrate fundamental skills to:
  - 4.1.1 communicate
  - 4.1.2 manage information

  - 4.3.1 work with others
  - 4.3.2 participate in projects and tasks
5 identify possible life roles related to the skills and content of this cluster
- 5.1 recognize and then analyze the opportunities and barriers in the immediate environment
- 5.2 identify potential resources to minimize barriers and maximize opportunities
