Modeling and investigation of physical machining processes

Modern approaches in metalworking differ high productivity during manufacture complex details from different steels and alloys with different parameters of hardness and strength. High manufactured metalworking is realised on modern metal-cutting machines and machining centers. An important problem of treatment is the optimum choice of mechanical machining technological parameters, which includes cutting mode, metal - cutting tool construction, monitoring and measurement means. Taking into consideration economic feasibility in the condition of real production during processing of new materials it is important to choose the cutting tool and treatment modes correctly. The choice of optimum variants is achieved after analysis of experimental data of the physical processes of mechanical treatment, which include temperature and cutting forces, vibration diagnostics, energy costs, wear of the cutting tool. Based on the measurement results of the physical parameters of the cutting zone, a physical model is created, together describing quantitative parameters of mechanical treatment process. The physical parameters measurements of mechanical treatment zone are realized in the real time mode with usage of appropriate primary information sensors associated with the National Instruments LabVIEW software package. The complex is an international standard in the system for physical processes measurement and modeling. The paper presents methods for studying and modeling the physical processes of mechanical treatment at the stage of choosing the optimal solutions for the parameters of mechanical treatment during training of specialists in the field of designing of machining and tooling complexes in mechanical engineering.
