Abstract

The invention discloses a numerical control machining process parameter self-adaptive control method. A numerical control machine tool three-dimensional simplified model is established based on a machining process self-adaptive parameter database, multiple modes are adopted for conversion control, and self-adaptive control over machining process parameters is achieved in the mode of combining PIDfuzzy controller control with manual control. According to the numerical control machining process parameter self-adaptive control method, the control of the PID fuzzy controller becomes more and moreaccurate and closer to reality, the PID fuzzy control method is adopted and the machining process parameter self-adaptive control method is realized, the full-load operation of the device can be guaranteed under the premise that the machining precision is met, and the energy-saving and environment-friendly efficiency is achieved; meanwhile, the parameter control method is improved, rapid compensation can be conducted on changes of internal characteristics of the system and external disturbance influences, it is guaranteed that the whole machining process is smooth and stable and it is guaranteed that the quality of machined products is more ideal.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a method for self-adaptive control of process parameters of numerically controlled machining. Background technique [0002] The manufacturing industry is the primary industry, the main body of the country's real economy, the guarantee of national security, and an important part of enhancing the country's core competitiveness. [0003] In the machining process, conventional controllers are used to set processing parameters, but conventional feedback control has certain robustness, but because the controller parameters are fixed, when the uncertainty is large, the performance of the system will drop significantly , or even instability, may lead to a certain impact on product quality. Contents of the invention [0004] (1) Solved technical problems [0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides...
