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.
