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.
Key words:
