This course is intended to teach types and characteristics of manufacturing methods to undergraduate students with the aim of understanding fundamentals of manufacturing processes. First, an overview of the basic various manufacturing methods used in the production of industrial products, including mechanical components, electric and electronic parts, will be taught, followed by the introduction of manufacturing process of the products. In particular, manufacturing methods of the components are focused, and students are allowed to understand fundamental characteristics and application of manufacturing processes, based on gaining the knowledge on the principle of manufacturing method in connection with the characteristics of materials. These knowledge are essential to perform functional and structural design of the products. Furthermore, students are allowed to learn how to select appropriate manufacturing method in accordance with the product.
1. Deformation processes (casting, plastic deformation processes, etc.)
2. Material-removal processes (cutting, grinding, etc.)
3. Joining processes (welding etc.)
4. Materials (microstructure, mechanical properties, etc.)
By the end of this course, students will be able to:
1. Understand the fundamentals of manufacturing process, and advantages and drawbacks of each process as follows.
casting, forming of plastics, welding and joining processes, rolling, extrusion, drawing, sheet-metal forming processes, forging, cutting, metal die manufacturing and CAE, grinding, polishing, electrical processes, laser-beam machining, surface treatment, coating, additive manufacturing, micromachining
2. Gain the knowledge on the relationship between materials' microstructure/properties and processings.
3. Select appropriate materials processing method applied for individual industrial component.
