Course description and aims

Many types of manufacturing processes are applied to fabricate machinery performing useful functions. Here, higher precision is crucial for developing the functions. This course aims to clearly understand and acquire the principles underlying the modern processing for achieving higher precision from the viewpoint of manufacturing technology.
1. The requirement for the fabrication of high precision machinery is clarified on the basis of what the development of machinery is.
2. Common features existing through a lot of manufacturing processes are generalized, and the technical elements and the processing principles that are necessary for higher precision are revealed.
3. Advanced manufacturing technologies in modern industry are extracted and the working principles are found out.

Student learning outcomes

Machinery that performs useful work with their advanced functions is produced by many types of manufacturing technologies, and the useful work is achieved by higher precision of manufacturing processes. From this point of view, you will acquire knowledge and ability to
1) explain the principles of manufacturing processes that contribute to the achievement of high precision
2) explain the principles of each manufacturing processes that you have learned in the undergraduate course from the viewpoint of high precision
3) discover the principles applied to the production of modern high-precision machinery.

Keywords

high-precision machinery, machining precision, principles of processing, machining unit, forced machining, selective pressure machining, processing energies, multistage machining, workpiece materials

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

The lectures will provide the structure of high-precision machinery, the concept of machining precision, the principles underlying various manufacturing processes for achieving high precision. Every class is allotted for you to explore and find the principles used for production of modern advanced machinery with high-precision and the novel manufacturing processes based on new principles.
