tolerance chart illustrates visually the manufacturing sequence of all operations to make a product. In this paper the difficulties of dealing with angular features in a tolerance chart are analysed. A 2D angular tolerance chart is constructed and presented. Then, the algebraic approach is used to determine the working dimensions and to check the tolerances. This 2D tolerance chart can deal with angular features, as well as square-shouldered features. A 2D tolerance chart can be simplified to be a 1D tolerance chart when the features are all square-shouldered.
