Study on the Optimization Process Technology in NC Machining Based on the Polychromatic Sets Theory

Abstract

Polychromatic sets theory is used for boxes parts CAPP expert system so as to store knowledge rules of selecting machining method in form of contour matrix. Through the logic operation of coloring in the knowledge based, the machining schemes relating to the features can be obtained. Genetic algorithm is used to sequence machining step in the machining center to make the process of sequencing machining step more flexible and convenient, and the result of sequencing machining step more reasonable.
