Title: Machine a variety of materials.
Course: Precision Machining Technology II (13204-II) > Section: Applying Metalworking Theory

Machining should include

- applying material properties theory
  - predicting speeds and feeds and tooling requirements based on known properties of a material
  - responding to cutting conditions imposed by material properties
- identifying common materials and their principal properties relevant to machining tasks
- recognizing differences among ferrous and nonferrous, magnetic, and ductile materials
- explaining the changes to materials caused by heat-treating
- predicting the machinability of a part based on its appearance, its call-out value on the blueprint, and its supplied hardness value.

Process/Skill Questions

- What is the difference between ferrous and nonferrous materials?
- What happens to steel when it is heat-treated?
- How do materials affect speeds and feeds?
- What is the difference between ductile and brittle materials?
- How do different materials affect tool life?
- Why is it helpful to know the melting point when machining various materials?
