Outline:
Processing methods for metal materials are classified into melt processing, removal processing, plastic processing. Various machine parts are manufactured by selecting the most suitable materials and processing methods. In this lecture, you will acquire basic knowledge of metal materials and learn about melting processing and removal processing. In addition, the purpose is to develop the ability to select the most suitable machining method for the workpiece by understanding the basics of various machining methods and machine tools.
Style:
In principle, classes are conducted in lecture format. Before the regular exam, we will conduct a summary practice problem. A quiz may be conducted to check understanding.
【60 class hours】
Notice:
The content of the class and the content of Machine Tool Experiment Practical Training 1 are closely related. Deepen your understanding in relation to lathe machining, milling machine machining, drilling machine machining, arc welding, etc. performed in practical training.
