Profile controls describe the three-dimensional tolerance zone around a surface Line Profile compares a two-dimensional cross-section to an ideal shape.The tolerance zone is defined by two offset curves unless otherwise specified.Surface Profile creates through two offset surfaces between which the feature surface must fall.This is a complex control typically measured with a CMM. results for this questionWhat is a 3-dimensional tolerance zone?What is a 3-dimensional tolerance zone?3-Dimensional tolerance zone existing of 2 parallel surface curves that follow the contour of the surface profile across the entire length of the surface.This tolerance zone may or may not be referenced by a datum.Gauging / Measurement Profile is usually measured using a CMM due to the complexity of some of the surfaces that are called out.Profile of a Surface GDT Basics results for this questionWhat is geometrical dimensioning and tolerancing?What is geometrical dimensioning and tolerancing?Geometrical Dimensioning Tolerancing (GDT) MEM 201 Department of Mechanical Engineering and Mechanics Todays Objectives..

As an alternative to the functional tolerances in Annex B,BS EN 1090-2 does allow the use of BS EN ISO 13920; this is more likely to be used in cases of heavily welded structures where distortion from welding is the dominant factor in determining the dimensions and shape.That standard specifies general tolerances for linear and angular An Introduction to Geometric Dimensioning andconventional tolerances with a +/- tolerance in two right-angle dimensions (two dimensions to a hole for instance),the tolerance zone is rectangular shaped.This is shown below in Fig 13.If both hole location tolerances are equal,then the zone will be square shaped.TheComplete Surface Finish Chart,Symbols Roughness LaySurface RoughnessWavinessThe Lay is the direction of the predominant surface pattern,and is usually determined by the production method used to process the surface.Here are some typical Lay patterns Surface Finish Lay PatternsSee more on cnccookbookThe ASME Y14.5 GDT Standard GDT BasicsSections five through nine each describe tolerancing of one of the following fundamental categories Form,Orientation,Location,Profile,and Runout.SECTION 1 SCOPE,DEFINITIONS,AND GENERAL DIMENSIONING This section outlines the scope and intent of
