Evaluation of the influence of the reaction rate of the thermodynamic subsystem on the dynamics of the cutting process in metalworking

OBRABOTKAMETALLOV Vol. 23 No. 2 2021 TECHNOLOGY Fig. 5. Graphs of force, temperature, and the coef fi cient that characterizes the chip pressure on the front face of the tool Fig. 6. Graphs of the coordinates of the tool deformation when cutting T Q = 0.85 Fig. 7. Phase trajectories of strain coordinates at T Q = 0.85 As can be seen from fi gure 9, the conducted studies have indeed shown the presence of a local minimum of the curve re fl ecting the dependence of the vibration energy of the instrument on the reaction time of the thermodynamic subsystem. Figure 9 also shows that the constructed calculated curve accurately re fl ects the local minimum obtained as a result of the experiment in the Matlab system.
