Course Objectives
Learning purposes :
It is one of the missions of a mechanical engineer to "manufacture good products quickly and economically". Therefore, it is necessary for a machine engineer to have the ability to plan an appropriate and rational process based on the knowledge of the basic characteristics of various machining methods. In machining, students are expected to be able to select an appropriate and rational means of manufacturing and to set appropriate working conditions.
Course Objectives :
1. To understand the basic engineering method for mechanical material and mother machines.
2. To be able to explain the model of removal processing after understanding the phenomenology of removal processing.
3. To be able to demonstrate guidelines for selecting mother machines and machining conditions based on knowledge of the basic characteristics of removal processing.
4. To be able to demonstrate guidelines for reasonable solutions to problems that may occur during processing.

Relationship with JABEE programs : The main goals of learning / education in this class are (A), Ａ－２.
Course outline : This course mainly deals with removal processing (machining using mother machines, and students learn various machining methods, their principles and characteristics, and the basic theory of machine tools as the basic knowledge for engineers studying mechanical engineering. In addition, based on the knowledge acquired through laboratory experiments, machining techniques and their significance are reviewed.
Style:
Course method :
The class is taught mainly on the board, paying attention to the relation to what was learned in the laboratory exercises. In addition, assignments will be given according to the students' progress in order to deepen their understanding.
Grade evaluation method :
The results of the two regular examinations will be evaluated equally (70%). Students are not allowed to bring textbooks and notebooks to the examinations. Students will be required to submit assignments (30%) as appropriate.
Notice:
Precautions on the enrollment :
This course is a mandatory course with 15 credit hours per credit, plus 30 credit hours of study per credit. Students must follow the instructions of the instructor.
Course advice :
It is necessary to study the textbook and reference materials in preparation for the laboratory exercises. Students are expected to solve exercises to deepen their understanding.
Foundational subjects : Introduction to Science and Engineering (1st year), Science and Engineering Laboratory (1st), Mechanical Systems Engineering Laboratory I (Mechanical 2nd), Materials Science (Mechanical 2nd), etc.
Related subjects : Graduate Studies (5th years), Production Engineering (5th), Special Experiments (advanced course 1st year), and Precision Machining (advanced course 1st), etc.
Attendance advice :
In "Materials Processing", the understanding of technical terms and the principles and characteristics of manufacturing are compulsory for engineers studying mechanical engineering. Students are expected to keep in mind the relationship between design and manufacturing.
