Precision machine is universal from instruments to automobiles and airplanes or from mechanical watches to spacecraft. What parts are they made up of? How do they drive? This course will focus on the characteristics, composition, function, principle and design method of the parts in the motion system with precision machinery, and guide the students in the world of precision machinery to experience the magic and subtlety of precision machine.
