Increasing the Performance of Computer Numerical Control Machine via the Dhouib-Matrix-4 Metaheuristic.

The Computer Numerical Control (CNC) machine represents a turning point in today's production which has high requirements for product accuracy. The CNC machine enables a high flexibility in work and time saving and also reduces the time required for product accuracy control. Moreover, the CNC machine is used for several activities, most often for turning, drilling and milling operations. Usually, the productivity of any CNC machine can be increased considering the minimization of the non-productive tool movement. In this paper, the results of a new metaheuristic named Dhouib-Matrix-4 (DM4) with an application on the NP-hard problem based on the Traveling Salesman Problem are presented. DM4 is used for increasing the performance of the CNC Machine by optimizing a tool path length in the drilling process performed on the CNC milling machine. The proposed algorithm (DM4) achieves a solution closed to the optimum, compared with the results obtained with others standard methods. [ABSTRACT FROM AUTHOR]
