MET114Christopher Ramey8-3-20Unit 1 Review Assignment 1Chapter 1:1. Geometric dimensioning and tolerancing is a symbolic language used to specify the size, shape, form, orientation, and location of features on a part.3. GD&T was designed to ensure the proper assembly of mating parts, to improve quality, and to reduce cost.4. Geometric tolerancing allows the maximum available tolerance and, consequently, the most economical parts.6. Plus or minus tolerancing generates a rectangular-shaped tolerance zone9. Bonus tolerance equals the difference between the actual mating envelope size and the MMC of thefeature.Chapter 2:1. Each dimension must have a tolerance except those dimensions specifically identified as reference, maximum, minimum, or stock.3. Dimensions must not be subject to more than one interpretation.
7. All dimensions and tolerances are applicable at 68⁰F (20⁰C) unless otherwise specified. Measurements made at other temperatures may be adjusted mathematically.
