Study on the Strategic Decision of Processing Scheme for Box- type Parts Based on Polychromatic Sets Theory

摘要

Polychromatic sets theory is used for box parts CAPP expert system so as to store knowledge rules of selecting machining method in the form of contour matrix. The rules can be adopted to provide a new way to build process knowledge base. Through the logic operation of coloring in the knowledge base, the machining schemes relating to their features can be obtained; meanwhile, it meets the requirements of the strategic decision for multi- process.
