Course Description

An elementary course describing the relationship between microstructure, composition, heat, and mechanical treatment and physical properties of metal and alloys; their relationship to design and machining. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

1. Demonstrate proper use of Tensile and Rockwell Testing machines to measure the strength of common aluminum and steel samples.
2. Identify the basic machining characteristics of aluminum, steel and copper based alloys.
3. Describe the cutting characteristics of high speed steel and carbide cutting tools on aluminum, carbon steel, and copper based alloys.

Course Objectives

• 1. Describe the properties of metals and alloys which are used in industry.
• 2. Converse effectively in the metallurgical language.
• 3. Define the role of metallurgy to the designer, machinist, tool, and diemaker.
• 4. Describe the relationship to speeds and feeds to alloys.
• 5. Converse accurately about why common metals and metal groups machine as they do.
• 6. Accurately perform a Rockwell hardness test.
• 7. Discuss how hardness affects the machining process.
