**课程名称：** GD & T 在零部件中的应用及案例分析 **课程概述：** 这是一门独一无二的、基于实际应用的先进课程，专注于几何尺寸和公差（GD & T）。本课程将 GD & T 知识与实际零部件设计相结合，教授如何制定公差方案以及它对装配的影响。 课程首先介绍理解零部件、其要素的功能关系以及在工程图纸上应用 GD & T 的通用方法。随后，将通过详细的案例研究，深入到零部件的细微之处，探讨与产品功能相匹配的几何尺寸和公差方案的应用。 **课程内容涵盖：** 1. **基准基准方案的建立：** 如何根据实际应用设定基准基准方案。 2. **几何控制的设定及其含义：** 如何设定几何控制及其具体含义。 3. **复合位置度/轮廓度控制的应用及其物理意义：** 复合位置度/轮廓度控制的使用场合、含义以及在量规中的物理意义。 4. **基于 GD & T 图纸的检验和功能量规程序：** 理解物理意义及对系统装配的影响。 5. **不同控制选用的推理：** 解释为何选择某些控制而非其他控制的原因。 **案例研究包括：** 汽车万向节轭、特种法兰、特种锁扣、转向轴安装支架、自行车车把安装系统、摇臂机构等多种零部件。 **课程目标：** 培养将 GD & T 应用于实际零部件的**概念性思维**。 **课程创办原因：** 许多工程师将 GD & T 仅仅视为另一个标准或一个仅用于图纸的工具，而忽略了其概念性应用。GD & T 是创建清晰、功能性工程图纸的强大工具，能够建立特征之间的关联。本课程旨在通过模拟工业实际情况，帮助工程师真正理解 GD & T 的应用。 **学习成果：** * 能够解读零部件的功能特征并应用公差方案。 * 在实际工业环境中，培养对 GD & T 应用的**坚实的**概念性理解。
This is one of a kind advanced application based course for Geometric dimensioning and Tolerancing which blends the GD & T knowledge with actual component design and how to develop a tolerancing scheme and how it impacts assembly. The first section of course deals with a generic methodology in understanding g a component , the functional relationships of its elements and applying GD & T on engineering drawing.Followed by a Elaborate set of case studies which go in deep to smallest details of the component and application of Geometric Dimensioning and Tolerancing scheme that aligns with the product function.1. How to set up datum scheme based on application 2. How to set up Geometric controls and their meanings 3. Where composite positional/ profile controls are used their meanings and physical meaning in gauges. 4. Inspection and Functional gauging procedure based on GD & T drawing to understand the physical meaning and affect on assembly of system. 5. The reasoning behind the usage of certain controls over others. Case studies include components ranging from the Yoke of a universal joint , Special flanges , Special latch, Steering shaft mount brackets, Bike Handle bar mount systems, Rocker arm mechanisms, etc. The aim of the course is to bring out the conceptual application of GD & T on actual components. Reason behind creating this course is that most engineers look at GD & T as only another standard or something to learn to just use on the drawing. But the conceptual understanding of application is missed out. GD & T is an amazing tool to create a very clear and functional drawing. Allowing to relate features to each other. As an engineer, having had the experience first hand the impact a good GD & T drawing can have. I have tried to create a learning resource which can replicate the situations in industry. Learning outcomes: Ability to interpret a components functional features and apply a tolerancing schemeDevelop a strong conceptual understanding of application of GD & T in actual industrial setting
