Abstract

The invention relates to a method for dispatching NC machine tool processing tasks and cutting tools. The method includes the following steps: 1. producing an initial solution group; 2. calculating the randomly generated system passing time under N different sequences of processing tasks and evaluating the advantages and disadvantages according to the calculation results; 3. genetic operator according to genetic calculation: replicating, intersecting and variation; selecting k optimal solutions to generate N new different sequences of processing tasks for each processing device Mi; 4. reevaluating the advantages and disadvantages of each sequence of processing tasks until finishing the preset times of calculations; 5. taking the optimal solution of the last calculation, that is, the sequence of different procedures for processing different workpieces on each processing device Mi, as the last dispatching result of NC machine tool processing tasks. The invention solves the dispatching problem of NC machine tool processing tasks and cutting tools, which is particularly suitable to the system of NC machine tool network control. The invention can effectively increase the operation efficiency of automatic production system.
