By default, the GPS characteristic is the local diameter (

16、two point size). Other type of size characteristic can be defined (see ISO 14405-1, e.g. 20 0,08 ).Locating the section plane a distance of 0 mm from the end plane is ambiguous on a real workpiece, due to the possible imperfections of the corner and should be avoided.Indication of location specifica

20、 20 EXAMPLE 8 Cone tolerancing - angle between two opposite generatrices. Any local angle, located in any longitudinal section, defined between two contacting straight lines, is required to be within tolerance. A longitudinal section is obtained by a plane that contains the axis of the associated co

These straight lines are established wi
