Abstract
Under the background of the rapid development of manufacturing industry, CNC machine tool, as the core equipment of modern industrial manufacturing, the improvement of its performance plays a vital role in promoting industrial progress, improving product quality and production efficiency. Servo system, as a key part of the CNC machine tool, is responsible for the accurate control of the movement of the machine tool, and its stability directly affects the machining accuracy and the overall performance of the machine tool. However, in practical application, the servo system is faced with many stability problems such as the response instability, high external interference sensitivity, poor parameter adaptability and long operation reliability. These problems not only affect the machining accuracy of the machine tools, but also may lead to the production interruption and increase the maintenance costs. This paper studies the stability of CNC servo system, and analyzes the challenges of unstable response, high external interference sensitivity, poor adaptability of parameter change and long time operation reliability. In order to solve these problems, this paper puts forward a series of improvement strategies, including enhancing the system response ability, optimization control algorithm, improve the system stiffness, improve anti-interference ability, using filtering technology, enhance power stability, parameter adaptive adjustment, the introduction of intelligent control, regular automatic calibration and improve the long-term operation reliability, etc. These strategies aim to comprehensively improve the stability of CNC machine tool servo system, so as to improve the machining accuracy and production efficiency of machine tools.
