Welcome to the journey of GD&T!
GD&T is a functional language between designer and manufacturer. It is growing, it is maturing, it is shaping itself. It is improving quality and efficiency. It is in huge demand in industry because it is saving costs! Want to know, how? Read on…
This book begin with the origin of GD&T. It will take you to fundamentals of dimensioning and tolerance with help of hole and shaft basis systems, for example basic/nominal size, limit, tolerance, actual size, deviation, allowance, and many such terms.
Further, it will it will take us to learn mechanical features, on which we apply GD&T and related terms, e.g., feature of size (FOS) and feature material condition (MMC/LMC/RFS), Datum, Datum feature frame, degree of freedom, datum target, datum simulators.
After covering fundamentals, It we will plunge in the core of the GD&T to learn fourteen geometric tolerances (straightness, flatness, circularity, cylindricity, etc.), we will look at practical application of each tolerance, the impact of MMC/LMC, bonus tolerance, method of writing in feature control frame, and more.
Further, we will proceed to advanced concepts of boundary and envelope, MMB, LMB, RFB, virtual condition, resultant condition, unrelated and related actual mating envelopes, etc.
There are many additional topics covered in this book, e.g., 14 modifiers, working with ISO-286, IT grades, etc.
You will learn more than you may expect from any GD&T book.
All the best! Happy learning!
