Abstract

The invention provides a method for optimally sorting aircraft structural part automatic programming processing units based on a technological process. The method comprises the steps that the technological process is built, and the machining craft process of parts is built through the tree structure of the depth traversal process scheme according to an input technological scheme file; the machining units are grouped, a set of tool sequences is obtained according to a given technological scheme, the grouping rule of the machining units is built according to the machining units, target machining units and real-time make-up machining units with tools associated in the tool sequences, and the special requirements of different types of make-up machining units and technologies, and the machining units are divided into four groups; the machining units are sorted, an overall layering and a virtual layering method are adopted, rough machining deformation is reduced, and layered machining and sorting are achieved. According to the method, the sorting result conforms to the practical technological requirement, interference and excessive cutting in the machining process are effectively reduced, the machining path is short, and the machining efficiency is high.
