Abstract: A part processing planning method includes the following steps. Firstly, a specific tolerance of a nominal size of a part is obtained. Then, a predetermined tolerance of each of processes is obtained. Then, using a process dimension chain establishing technique, at least one predetermined tolerance associated with the specification tolerance from the predetermined tolerances is obtained. Then, at least one predetermined tolerance associated with the specification tolerance is accumulated to obtain a size cumulative tolerance. Then, whether the size cumulative tolerance meets the specification tolerance is determined. Then, at least one predetermined tolerance associated with the specification tolerance is re-allocated when the cumulative tolerance does not meet the specification tolerance, such that the size cumulative tolerance is within the specification tolerance.
