This allowable error range is also known as the geometrical tolerance. 2. Precision parts processing geometric shape accuracy Geometric shape accuracy refers to the accuracy of the geometric shapes of the surfaces or axes that make up the parts, such as whether the line is straight or not, whether the normal sections on the flat cylinder are round, etc. The allowable variation range is expressed by "geometric tolerance". The smaller the geometric tolerance number, the higher the shape accuracy. 3. Position accuracy Precision parts machining position accuracy refers to the accuracy of the mutual positions between the surfaces of the parts, such as whether the two planes are parallel or perpendicular or not, whether the two axes are coaxial, etc., which is expressed by "position tolerance".
