Abstract: The tolerance existing in the 4-coordinate side milling is classified into two types: the tolerance caused by the limitation of 4-coordinate NC machining and the tolerance caused by the different direction of the normal vector, the reasons are discussed and the calculating formulae of the two kinds of tolerance are given respectively. The distribution of the tolerance caused by the different direction of the normal vector along the straight generator line and an algorithm to decrease it is also given.
