Overview

This course is based on ASME Y14.5-2018. GD & T is the international language to describe the function of the parts, this language should precisely and uniquely specify the function of the parts as well as the feasibility of manufacturing and measurement.This course is designed to help either beginners or intermediate GD & T users to reach the experienced level. The whole course has 60 modules, which is designed from fundamental level to advanced level. Each module is targeted to dive into each GD & T knowledge in detail and in depth by using practical drawing cases. Then all of this points will be linked together to build the systematic knowledge of GD & T frame structure. We believe the philosophy, logic and relationship behind those various symbols is the key to make the learner to grasp the core understanding on GD & T. Just understanding the definition of geometric tolerance is not enough, we will explore the meaning of each geometric symbol from the angle of relationship, application and function, such as common and difference of each tolerance, how to define the datum based on the function, how to define the tolerance based on the function, how to evaluate the parts, how to design the function gage to verify the parts. The training includes 12 work-shop quizzes to help the students improve practical application skills, we have provide final test to verify the learning effectiveness. Bonus videos will be offered to improve the understanding the specific knowledge point. Long term question and answer service will be provided for free.This course mainly focus on ASME Y14.5-2018 contents are included. All of the teaching contend will be based on the latest GD & T standard. Introduction 1. IntroductionChapter 1 GD & T Principles and Rules2. GD & T Systems and Fundamental Rules3.
