Plantenberg Restricted use only Tolerancing Summary Copyright 2008 by K. Plantenberg Restricted use only Summary What will we learn in Chapter Tolerancing? We will learn about tolerancing and how important this technique is to mass production. Key points If a features size is toleranced, it is allowed to vary within a range of values or limits. Tolerancing enables an engineer to design interchangeable or replacement parts. Copyright 2008 by K. Plantenberg Restricted use only Tolerancing 8.1) Tolerancing for Interchangeability Copyright 2008 by K. Plantenberg Restricted use only Tolerancing / Interchangeability Tolerancing is dimensioning for interchangeability. What is interchangeability? An interchangeable part is simply a mass produced part (a replacement part). Copyright 2008 by K. Plantenberg Restricted use only Tolerancing / Interchangeability How is a feature on an interchangeable part dimensioned? The feature is not dimensioned using a single value, but a range of values. 1.00 1.005 .994 Copyright 2008 by K. Plantenberg Restricted use only Tolerancing / Interchangeability A tolerance is the amount of size variation permitted. You can choose a tolerance that specifies a large or small variation. 1.005 .994 Tolerance = 1.005 - .994 = .011 Size limits = Copyright 2008 by K. Plantenberg Restricted use only Tolerancing / Interchangeability Why do we want a parts size to be controlled by two limits? It is necessary because it is impossible to manufacture parts without some variation. The stated limits are a form of quality control. Copyright 2008 by K.
