Technical Electrodynamics| Zusammenfassung: | Using the example of modeling the longitudinal feed of the working body (WB) of a precision metal-cutting machine tool model 24K70AF4 during the cutting process (PC), the possibility of a significant comparative increase in the efficiency of electromechanical energy conversion in the electric drive (ED) of the machine tool feed is proven by using the proposed iterative two-channel ED with a conditional PC compensator (PCCC) instead of the traditional single-channel ED. This allows you to significantly improve the quality of WB feed control and, as a result, significantly increase the potential competitiveness of the output of heavy metal-cutting machine. Detailed simulation computer models of the compared two-channel and single-channel EDs have been constructed, which contain the corresponding dynamic models of the PC and the PCCC compensators and take into account the influence of nonlinear friction forces in the load on the dynamics of the drives. Indicative comparative electrodynamic characteristics of the systems were obtained. Significant (multiple times) potential advantages in the speed and accuracy of feed control of a dual-channel ED have been established. The modeling results showed for the first time that the accuracy of the feed of the WB in the metalworking mode can be significantly increased not only due to the iterative structure of the two-channel control system of the ED, but also additionally by building an electronic model of the PC itself and including this model together with the PCCC in the control loop of the feed ED.
