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.
