| Abstract: |
| This paper aims to study the computer-aided printing process planning without redundant computing in complex manufacturing system with multi print processes. First, based on the study of Polychromatic Sets Theory, the “Printing Requirements 2-layer Model” and “Printing Process 2-layer Model” were constructed according to the proposed hierarchical constructing method; Then, the minimal product comprising and contour comprising matrix were constructed according to the calculated available “Process Groups”; Finally, the available processes were calculated using the proposed hierarchical process search algorithm, and the printing process path could be searched in the polychromatic graph. As a result, the hierarchical printing process planning method based on polychromatic sets theory was proposed. In conclusion, the hierarchical printing process planning method based on polychromatic sets theory can effectively remove redundant computing in the process search algorithm. |
