A Study on the Improvement of Servo Control Characteristics of Ultra Precision Machine Tools by ANFIS-PID Controller

Authors: Su-Bom Yun, On-Jeng Sim

The demand for ultra-precision machining is increasing day by day. In particular, demand for ultra-precision processing products is increasing in many fields such as defense industry, space industry, and economy. Accordingly, ultra-precision processing technology is also increasing. However, the precision of machining varies depending on the environment. The most influential factors are vibration, temperature, and wear. Therefore, a special tool setting a micro-thermosensor is installed to measure the temperature change at the cutting point in real time. Recently, various artificial intelligence manipulation techniques have been studied to overcome these deficiencies. In this paper, we describe the improvement of the control accuracy compared to the previous controllers by applying the adaptive neuro-fuzzy controller that takes into account the model uncertainty of the subject and by conducting the simulation.
