Publisher Summary The quality and type of surface texture has a direct connection with the manufacturing cost, function, and wear of a component. Each of the symbols has their own special interpretation and individual surface texture values and text may be added to the symbols. The center line between the lines of unequal length is positioned square to the considered surface. The symbol should not be indicated alone, without complementary information although it can be used for collective indication. If complementary requirements for surface texture characteristics are required, then a line is added to the longer arm of the symbols. When the same surface texture is required on every surface around a workpiece, then a small circle is added to the symbol. The texture applies to all eight sides and if ambiguity is considered likely, then each surface can have its own independent symbol. To avoid ambiguity, it may be necessary to add additional requirements to the surface texture symbol and its numerical value such as machining allowances, manufacturing process, sampling length and surface lay. |
