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

Abstract

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 are used for several activities, most often for turning, drilling and milling operations. Usually, the productivity of any CNC machine can be increased thanks to the minimization of the non-productive of 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 Travelling 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 the Ant Colony Optimization algorithm and the results found with the manual programming in G code by using a control unit for the selected CNC milling machine.

Hierarchical Coverage Repair Policies Optimization by Dhouib-Matrix-4 Metaheuristic for Wireless Sensor Networks using Mobile Robot

“…In this paper, the new metaheuristic named Dhouib-Matrix-4 (DM4) is applied to hierarchically solve the coverage repair policies for WSNs. DM4 has been firstly invented by Dhouib [15] and performed to optimize the shortest path joining all nodes as reported in literature [16][17][18]. Hence, DM4 is a multi-start technique (see Figure 1) and for each start two independent methods are applied: At first, the novel column-row heuristic Dhouib-Matrix-TSP1 (DM-TSP1) is used to create several initial feasible solutions with different statistical metrics (Min, Max, Mean, Standard deviation etc.…”

The Development Trends of Computer Numerical Control (CNC) Machine Tool Technology

“…The Adaptive-Dhouib-Matrix-3 (A-DM3), an improvement over Dhouib-Matrix-3 (DM3), significantly shortens machining paths and saves energy consumption [35]. Additionally, the Dhouib-Matrix-4 (DM4) metaheuristic optimizes tool paths to enhance production efficiency [36]. Integrating various artificial intelligence systems into CNC machine tools would greatly benefit equipment manufacturers.…”
