Features: This book is based on the "Teaching Guidance Plan for the Main Courses of Mechanical Processing Technology in Secondary Vocational Schools" issued by the Ministry of Education in 2001, and refers to the occupational skill assessment standards of relevant industries as well as the grading assessment criteria for intermediate technical workers. It is a national planned textbook for secondary vocational education. The book mainly includes two parts: theoretical teaching and practical training. The theoretical teaching content includes: an overview of limit fits and technical measurement, limits and fits of hole and shaft dimensions, fundamentals of technical measurement, geometric and positional tolerances, surface roughness, and technical measurement. The practical training content includes: measuring internal hole diameters with a dial indicator, measuring flatness errors, measuring the tooth thickness of cylindrical gears with a gear vernier caliper, and measuring the pitch diameter of threads using the three-wire method. The book emphasizes practical application, introducing the provisions of the new standards in plain language and explaining the principles and methods of error detection, striving to combine theory with practice. It can be used as a textbook for mechanical processing technology in secondary vocational schools, or as a training manual for relevant industries or self-study material.
