The course of Interchangeability and Measurement Technology is basic technique course for the students whose major is associated with mechanical. Engineers and workers who design or fabricate machines should have the knowledge introduced in this course.
To the students who study in an engineer higher educational institutions，the following contents should be grasped after finish this course：
- To understand clearly the concepts and effects of interchangeability, standardization and measurement technology.
- To familiar with the basic content of every tolerance studied in this course, to know exactly the basic terms.
- To analyze fit properties and fit type during read an assembly drawing and to draw the size tolerance zone figure.
- During read a detail drawing (single part drawing), to know exactly the precision requirements about size, form, orientation, location, run out and surface texture. To be able to calculate the limits of size，to describe the form, orientation, location requirements for every feature, to draw the dynamic tolerance zone figure of tolerance principle.
- During draw a engineer drawing (assembly drawing and detail drawing), to indicate the precision requirements on the drawing correctly according to the standards.
