Answerbook for Geometric Dimensioning and Tolerancing: A Practical Reference for Applying ASME Y14.5 and Achieving Functional Precision

By Gerald T. Harmon

Geometric Dimensioning and Tolerancing - the complete answerbook for precision manufacturing, functional assembly, and inspection mastery.

You are standing at the CMM with a reject report in hand, staring at a part that fits perfectly in assembly but fails every inspection. Or you are designing a multi-component assembly and wrestling with tolerance stacks that check out on paper but bind on the shop floor. This book solves exactly those problems - systematically, practically, and in full compliance with ASME Y14.5.

Inside this reference:

GD&T symbols and feature control frames - tolerance zones, modifiers, and datum references decoded with step-by-step examples
Datum reference frames and datum targets - functional setups for castings, weldments, and non-rigid parts
Material condition modifiers MMC, LMC, and RFS - bonus tolerance calculations, virtual condition boundaries, and functional gage design
Position tolerancing - composite, multiple single-segment, projected zones, bidirectional, and zero at MMC
Profile tolerancing - unequally disposed zones, all-over, dynamic profile, and composite profile control
Tolerance stack-up analysis - worst-case arithmetic, RSS statistical methods, and fixed/floating fastener formulas
Inspection and metrology - CMM boundary method, functional gaging, optical measurement, and gage R&R
50 real-world application stories - solved problems from automotive, aerospace, medical, and heavy machinery
Quick-answer compendium - symbol tables, formulas, conversion charts, and an ASME Y14.5 rules reference

Every chapter opens with the most frequent questions from designers, machinists, and quality engineers. You get direct answers with actionable solutions, measurement strategies, and functional gage layouts - not just theory.

Grab this GD&T answerbook and get the answers you need to stop disputes, reduce scrap, and deliver parts that fit right the first time.
