This book is written to meet the practical needs of the teaching plan for the “Interchangeability and Measurement Technology” course. This book is compiled by combining the achievements of recent education reforms and the construction of national first-class undergraduate courses, adopting the latest national standards, with the feature of closely link theory with practical application.

This book includes 6 chapters. Chapter 1 provides a comprehensive introduction to the basic concepts of interchangeability and standardization. Chapters 2-4 introduce in detail the relevant content of size tolerance, geometric tolerance, and surface roughness from the perspective of accuracy design and basic knowledge reserve of national standards. Chapter 5 starts from error measurement technology and provides a detailed introduction to the basic content of geometric quantity detection technology. Chapter 6 provides a detailed introduction to the accuracy design of typical components for applications.

This book systematically introduces the basic knowledge of interchangeability and measurement technology, highlights basic concepts, provides specific analysis cases, and is equipped with exercise questions, aiming to deepen students’ understanding of the basic knowledge and apply it.

This book is suitable to be used as teaching materials or reference books for students majoring in machinery and instrumentation in higher education institutions, and can also be served as a reference book for mechanical engineering technicians.
