Rules of GD&T

ASME Y14.5 requires engineering drawings to be created and interpreted to a set of rules. Understanding these rules is important to understanding the design intent of a part. By the end of this course, you will be able to • Understand Rule #1 of GD&T • List tolerance zone shapes • Define size • Define the local size of a feature of size • Define actual mating size • Understand the implied 90-degree rule • Understand how to apply general, or block, tolerances

Geometric Tolerances

Engineers use geometric tolerances to convey the design intent of the form or location of features when size tolerances may be too restrictive. By the end of this course, you will be able to • List the geometric characteristics controlled by geometric tolerances • Identify the symbols used in geometric tolerances • Identify a feature control frame • Identify the tolerance area of a feature control frame • Identify the geometric characteristic area of a feature control frame • Identify the datum references area of a feature control frame • Identify a basic dimension

Datums

Datums are the foundation that provides a method of aligning geometric tolerance zones to ensure features meet their intended design. By the end of this course, you will be able to • Define a datum • Define a datum feature • Identify a datum feature symbol • Define a simulated datum • Define a datum reference frame • Identify a datum target symbol • Understand the importance of the order of precedence of datums

Form Tolerances

Form geometric tolerances are used frequently to control shapes of individual features of parts. Understanding the tolerance zone created by a form geometric tolerance is important for anyone involved in manufacturing. By the end of this course, you will be able to • Identify a tolerance zone for a straightness geometric tolerance • Identify a tolerance zone for a circularity geometric tolerance • Identify a tolerance zone for a cylindrical geometric tolerance • Identify a tolerance zone for a flatness geometric tolerance

Profile Tolerances

Profile geometric tolerances are used to define the limits of contours of lines and surfaces containing straight lines, arcs, partial cylinders, and even mathematically defined curves. By the end of this course, you will be able to • Define a tolerance zone for a profile of a line • Define a tolerance zone for the profile of a surface • Understand unilateral profile tolerancing • Understand bilateral profile tolerancing
