Interchangeability and measurement technology is a comprehensive basic subject of applied technology, and its formation and development are closely related to the development of mechanical and electronic industry. This subject combines the standardization field of interchangeable production with the related knowledge in the measurement field, involving the design, manufacture, quality control and production organization and management of electromechanical products. Technicians engaged in mechanical engineering should have these knowledge and abilities.

To learn interchangeability and measurement technology, we must first have the ability to read and draw pictures, understand the general mechanism principle of machinery, and master the preliminary basic knowledge of machinery manufacturing. The basic part of measurement technology will involve the knowledge of probability theory, so it is necessary to know something about engineering mathematics.
