FAB1130 Principles Of Machining

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

Description
Students develop basic hand and machine tool knowledge, skills and techniques to mechanically remove materials.
Prerequisite
FAB1010: Fabrication Tools & Materials
Parameters
Access to a materials work centre, complete with a drill press, bench or pedestal grinder and metal lathe, and to instruction from an individual with specialized training in basic machining.

    • 2.5 demonstrate basic skills in:

      • 2.5.1 measurement and layout

      • 2.5.2 drilling, grinding and turning operations to size, shape and finish a complete product

  • 3 demonstrate basic hand and machine tool knowledge, skills and techniques

    • 3.1 describe the current systems of measurement used in machining and explain the advantages and disadvantages of each

    • 3.2 list and describe common types of rules, squares, dividers, callipers, micrometers and gauges that are used in connection with machining

    • 3.3 identify the major components and describe the operation of a drill press

    • 3.4 research the design of a typical twist drill and methods of sizing

    • 3.5 describe the purpose and list the types of lubrication that are used when drilling

    • 3.6 identify the appropriate cutting tool to face metal stock

    • 3.7 explain what is meant by cutting speed, feed rate and depth of cut and how these variables are expressed and controlled

    • 3.8 identify the major components and operation of a bench or pedestal grinder

    • 3.9 identify and describe different kinds of grinding wheels

    • 3.10 explain why it is important not to overheat thin edges or points and not to grind soft metals
