**课程名称：** 几何尺寸与公差（GD&T）课程 (ASME Y 14.5) **课程概述：** 本课程旨在全面讲解几何尺寸与公差（GD&T）这一国际工程与制造领域广泛应用的标准化系统。GD&T 提供了一种清晰、标准化的方法来定义零件的几何形状、形态、方向、位置和跳动特性，这对于确保零件在装配中的正确配合和功能至关重要。 课程将介绍GD&T中14个基本几何符号，包括：平面度、直线度、圆度、圆柱度、轮廓（线）、轮廓（面）、角度、垂直度、平行度、位置度、同轴度、对称度、跳动（径向/轴向）和全跳动。这些符号用于定义特定的公差和变差，使工程师能够清晰准确地传达设计意图。 此外，课程还将涵盖基准、基准要素和基准修饰符等关键概念，以及公差符号的应用。学员将学会如何应用这些要素来创建精确的工程图纸，确保零件的正确对齐、功能性和可制造性，并符合ASME Y 14.5等行业标准。 理解公差是本课程的另一核心内容。公差定义了尺寸或几何特征可接受的变差范围，以确保零件在整体装配中能够正确配合和正常工作。课程将教授如何根据特征类型及其与其他特征的关系，来解读和应用各种公差，包括线性、角度和几何公差。特别是位置公差的应用将被详细探讨，以确保零件相对于基准和其他特征在规定范围内正确定位，这对于实现精确装配和功能至关重要。 **课程目标：** 完成本课程后，学员将： * 掌握GD&T的基础知识，能够读懂、理解和创建符合国际标准的详细工程图纸。 * 提升与制造团队的沟通能力，确保零件的生产准确、高效，并满足要求规范，从而实现成功的 product 组装和性能。
The Geometric Dimensioning & Tolerancing (GD & T) Course provides a comprehensive understanding of how to apply and interpret the internationally recognized system used in engineering and manufacturing to ensure precise and accurate part design and production. GD & T offers a clear and standardized way to define the geometry, form, orientation, location, and runout characteristics of parts, which are crucial for ensuring proper fit and function in assembly. This course introduces students to the 14 fundamental geometric symbols used in GD & T, which include: Flatness, Straightness, Circularity, Cylindricity, Profile of a Line, Profile of a Surface, Angularity, Perpendicularity, Parallelism, Position, Concentricity, Symmetry, Runout, and Total Runout. These symbols define specific tolerances and variations that allow engineers to communicate design intent clearly and accurately.This course covers essential concepts such as datums, datum targets, and modifiers, along with tolerance symbols. Participants will learn how to apply these elements to create precise engineering drawings, ensuring proper alignment, functionality, and manufacturability in accordance with industry standards like ASME Y 14.5.Understanding tolerances is another core aspect of this course. A tolerance defines the acceptable limit of variation for a dimension or geometrical feature, ensuring that parts fit and function correctly within the broader assembly. The course will teach how to interpret and apply different types of tolerances, including linear, angular, and geometrical tolerances, based on the type of feature and its relationship to other features. The application of position tolerance, in particular, is explored in detail, as it ensures that parts are located within specified limits relative to their datums and other features, essential for achieving accurate assembly and function.By the end of the course, students will gain a strong foundational knowledge of GD & T, empowering them to read, interpret, and create detailed engineering drawings that adhere to international standards. They will also develop the ability to communicate more effectively with manufacturing teams, ensuring that parts are produced accurately, efficiently, and within the required specifications for successful product assembly and performance.
