GEOMETRIC DIMENSIONING AND TOLERANCING (GD&T)
MAIN FEATURES OF GD & T DEFINITION: - GD & T is a systematic way of representing the dimensions and providing additional tolerances, geometric characteristics to the dimensions accordingly. WHY IT IS USED:- To avoid wastage of parts while assembling, due to minor error in dimensions. BASIC RULES OF GD & T:- 1. Limits of size of a feature control the amount of variation in size and geometric form. 2. RFS (Regardless of Feature of Size) applies with respect to the individual tolerance, datum reference, or both, where no modifying symbol is required. MMC or LMC must be specified on the drawing wherever required. FEATURE CONTROL FRAME:- ...
