The invention relates to a method for scheduling machining tasks and cutters of a numerical control machine tool. The method comprises the steps of 1, generating an initial solution group; 2, calculating system passing time lengths of N different machining task sequences which are randomly generated, and determining good or bad of the N different machining task sequences according to the calculation result; 3, performing copying, crossing and variation according to a genetic operator of a genetic algorithm, picking k optimal solutions for generating new N different machining task sequences foreach machining equipment Mi; 4, re-determining good or bad of each machining task sequence until a preset number of calculation times is finished; and 5, using the optimal solution in the final calculation result, namely the machining task sequence of different processes for machining each workpiece as the final numerical control machine tool machining task scheduling result. The method settles aproblem of scheduling the machining tasks and the cutters of the numerical control machine tool and is particularly suitable for use by a system for networking control of the numerical control machine tool. The method can effectively improve operation efficiency of an automatic production system.
