Consider a component as shown with dimensions and tolerances given . How can we find the specification in red? Generic process for Worst case tolerance stack up analysis Label the distance to be studied A-B Positive and negative directions are set Left to Right is positive Right to left is negative Develop loop diagram starting from A to B Start from A and move towards B through Loop The dimensions in positive direction are added together and dimensions in negative are added together Negative dimensions sum is subtracted from positive direction sum . All tolerances are added with each other . The total added tolerance is possible allowed variation for distance being studied Loop Diagram with the tolerance analysis table: For a full course on Tolerance stackup analysis with and without GD&T  have a look here : Basics of Tolerance analyses : Stackups and Fits Explore more topics in GD&T : GD&T symbols Interview questions in GD&T What is virtual condition in GD&T What is Rule #1 in GD&T Factors in Specifying tolerance GD&T tolerance zone GD&T straightness GD&T runout GD&T resultant condition GD&T Regardless of feature size GD&T profile tolerance GD&T perpendicularity GD&T parallelism GD&T maximum material condition GD&T least material condition GD&T functional gauge GD&T flatness GD&T Feature of size GD&T feature control frame GD&T datum reference frame what is datum feature in GD&T What is datum feature modifier Circularity and Cylindricity What is bonus tolerance What is actual mating envelope What is 3-2-1 principle in tolerancing Applying GD&T scheme to a bracket Types of Fits in tolerancing GD&T applied to patterns of features Tolerance stack up analysis of a simple part What are material conditions in GD&T Composite position tolerance in GD&T What are datum targets in GD&T Auxiliary datum in GD&T Verification of manufactured GD&T drawing What are simultaneous requirements in GD&T Calculating the geometric tolerance of a part Developing GD&T scheme for a part Traditional tolerancing vs GD&T How to learn GD&T an approach
