课程名称：几何尺寸与公差（GD&T）：基础 课程概述： 该课程旨在从工程图的基本概念开始，逐步推进到更复杂的理念。课程首先解释工程图的重要性，然后阐述GD&T的必要性，深入探讨GD&T的核心概念。如果你是完全的初学者，课程将循序渐进，帮助你掌握GD&T的基本要义；如果你是经验丰富的专业人士，课程后半部分将对你非常有帮助。 几何尺寸与公差是用于在工程图上传达设计意图的一种知识体系和符号语言，适用于制造和检验。课程将教你核心GD&T概念的构建及其在多种图纸中的应用，通过多个实例展示它们的重要性。你将了解到相较于传统尺寸标注方式，GD&T语言的优势，以及通过各种符号和控制组合来管理零件变异的可能性。 课程涵盖以下主题： - 工程图的总体视角及其重要性 - GD&T的必要性 - GD&T的入门概念 - 传统公差方法与GD&T的综合比较 - 基准（Datum）的详细探讨：基准是GD&T中最重要的概念，它们是如何创建与应用的，在图纸上代表什么 - 奖励公差（Bonus Tolerance）与虚拟条件（Virtual Condition）的概念，它们在配合部件中扮演重要角色 - 符号及其检验方法的详解，包括：形状、直线度、平面度、圆度和圆柱度、方向、角度、垂直度、平行度、位置、对称性及同心度、跳动、轮廓 - 基准功能修饰符（Datum Feature Modifiers）或基准偏移的概念 每个部分都有测验，课程中还包含练习习题，以帮助你练习GD&T技能。课程设计上，针对每个要点都设有多个简短的讲座，信息精练且直接。课程结束时，将进行一个包含30个有深度的问题的测验，以考察你对该主题的理解。
The course is designed in a way to build from the basic concepts of engineering drawing towards more complex concepts. It starts with explaining the importance of an engineering drawing and going on to explain why GD & T the need has arisen and then a deep dive into the concepts of GD & T If you are a total beginner the course will build progressively in terms of concepts to capture the core tenets of GD & T.If you are a seasoned professional then the latter portions of the course will be useful to you Geometric dimensioning and tolerancing is a body of knowledge and a symbolic language used to communicate design intent on an engineering drawing for manufacturing and inspection. In this course you will learn , how exactly are the core concepts of GD & T built and how they are applied to drawings with multiple examples.You will learn and appreciate the importance of the language over the traditional way of dimensioning and learn the possibilities of controlling the parts' variations using various combinations of symbols and controls.The course will cover the following topicsOverall perspective of what an engineering drawing is and why it is important. The Need for GD & T then moving towards the introductory concepts of GD & TA comprehensive comparison of Traditional method of tolerancing vs GD & T A detailed look at Datums the most important concept in GD & T , How are they created? How are they applied? and what do they mean on the drawing?A detailed look at Bonus tolerance and concept of virtual condition which lays a key role in Mating parts.Explanation of Symbols and their inspection methodsFormStraightnessFlatnessCircularity and cylindricityOrientation AngularityPerpendicularityParallelismLocationPositionSymmetry and ConcentricityRunoutProfileFinally we will have a look at the concept of Datum feature modifiers or Datum shift.Each section has a Quiz and you will find practice exercises to practice your GD & T skills.The course is designed in such a way that each and every point is captured as a sub topic with multiple short lectures which are to the point with condensed information. At the end of the course, take a quiz with 30 insightful questions which will test your conceptual understanding of the subject.
