Course DescriptionCovers the manufacture, types, heat treatment, testing, machinability, properties and the physics of materials and material removal of ferrous and non-ferrous materials. Introduces the processing of materials to obtain the desired changes in its physical properties, the non-destructive and destructive testing of materials, the machinability of materials and the efficiently/required knowledge of the metal to be cut, but also how the cutting tool material and its shape will perform under various machining conditions. Prerequisite: MCH 100.
Addendum to Course DescriptionMETALLURGY consists of the following modules:
Intended Outcomes for the course
The student will be able to understand and demonstrate the proper setups, uses and operations associated with industry standard processes for the manufacture, heat treatment and testing of metals/materials. The student also will be able to understand the theory and applications associated with the physics of metal cutting and the machinability of metals/materials.
This course is based on performance outcomes. The following performance outcomes are based upon established industry standards. The student will demonstrate knowledge and understanding by completing the following activities:
- In this module the student will identify six properties of metals; explain the processes by which Iron and Steel are made; and describe the effect of alloying elements on Steel.
- In this module the student will select the proper grade of tool steel for a workpiece; harden and temper a carbon-steel workpiece; and caseharden a piece of machine steel.
- In this module the student will explain the three methods of hardness testing; perform a Rockwell C hardness test on a workpiece; Perform Tensile strength and impact tests on a workpiece; Describe several nonferrous metals used in industry.
- In this module the student will define various terms that apply to metal cutting; explain the flow patterns of metal as it is cut; and recognize the three types of chips produced from various metals.
- In this module the student will explain the factors that affect the machinability of metals; describe the effect of positive and negative rake angles on a cutting tool; assess the effects of temperature and cutting fluids on the surface finish produced.
Course Activities and Design
METALLURGY will be presented by means of audio-visual presentations, demonstrations, lab experiences, and research activities. The course activities and design emphasize the development of skills and knowledge outcomes prescribed by established industry standards. The identified outcomes will be achieved by means of individual and team activities.
