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.

Description

technical field [0001] The invention relates to a CNC machine tool production, processing and manufacturing system, especially a CNC machine tool networking manufacturing system, which considers the existing processing load of the machine tool, and realizes the management goal of completing the processing task in the shortest time through reasonable allocation of tools and processing tasks Scheduling methods for processing tasks and cutting tools. Background technique [0002] For complex, multi-variety, medium and small batch automated manufacturing systems, production planning and scheduling technology is one of the key technologies for whether the manufacturing system can achieve the expected economic benefits. Its goal is to achieve the purpose of improving production efficiency, shortening the manufacturing cycle, improving the utilization rate of production resources, and ensuring the efficient operation of the production system through reasonable planning, scheduling ...
