This course is highly practical, incorporating several practical cases (especially classic error cases) throughout the training. These cases will guide students to analyze the advantages of GD&T in design, assembly, inspection, and application, enabling them to understand and learn to apply GD&T effectively. The content of this course is equivalent to the ASME Y14.5M-2009 standard.

Course Overview

Common problems and misconceptions in enterprises

• How to scientifically loosen tolerances? What are some new tolerance application experiences?
• How to reduce technical disputes, simplify measurement work, thereby reducing measurement risks, and avoiding occurrences of misacceptance and rejection?
• How to improve R&D level, save manufacturing costs, and increase qualification rate?

Course Benefits

• Correct interpretation of GD&T symbols, terms, rules, and application methods;
• Mastering the analysis of fitting from the perspective of part functionality, correct selection of datum, and assembly analysis;
• Mastering methods for unified form and positional tolerance measurement and evaluation, reducing manufacturing and inspection difficulties;
• Mastering basic knowledge of simple GD&T gauges.

Suitable People

• Design, quality, process, and manufacturing engineers, inspectors, CMM operators, and individuals involved in interpreting, using, and drawing engineering drawings;
• Basic ability to read mechanical drawings and some practical work experience in design, process, or measurement.
