Students in this course learn about the basic components of machinery for which precision motion is important, such as ultraprecision machine tools, exposure devices, 3D measuring machines, etc., the type and properties of components selected for the basic configuration, design techniques, as well as precision measuring technology and control methods that are needed for motion systems that use that machinery. The instructor also introduced trends in their use.
High-precision movement is a basic and important capability which can be implemented by understanding real machine problems in greater detail and solving them. The purpose of this course is to acquire basic knowledge and skills for this task.
Students will acquire the following skills by taking this course.
1) Learn basic knowledge of machines for precision and ultra-precision motions, and gain an understanding of precision deterioration factors.
2) Gain an understanding of basic principles of sensors and properties of control methods for precision and ultra-precision motions, and be able to choose appropriately.
