精密工程是交叉学科领域，主要包括精密设计，精密制造和精密测量三个方面，涉及测量，材料，机械加工过程，机械设计，微传感器和驱动器，集成电路制造，新型制造方法等。本课程主要侧重于精密设计和精密制造两方面，主要内容分为三个部分：第一部分介绍了精密工程的含义和相关概念；第二部分内容为精密设计理论，介绍了精密工程中与设计需要遵循的相关原则；第三部分内容为精密加工理论，介绍了与精密加工相关的原则。

Precision engineering is a multi-discipline area including precision design, precision machining and precision measurement. This subject has a close relation with measurement, material, mechanical processing, mechanical design, micro sensors and drivers, IC manufacturing, novel processing methods and so on. The content of this course is concentrated on precision design and machining. In the first part, the meanings and correlated concepts of precision engineering were detailed introduced. The theory of precision design including various design principles were described in the second part. The third part was about theories of precision machining.
