CURRENT SITUATION AND DEVELOPMENT COUNTERMEASURES OF THERMAL ERROR COMPENSATION TECHNOLOGY IN CNC MACHINE TOOLS
ABSTRACT
CNC machine tool is the key equipment of modern manufacturing industry, and its machining accuracy has a direct effect on product quality and production efficiency. Thermal deformation is the main factor affecting the machining accuracy, especially in precision machining, the thermal error can account for 40% to 70% of the total error. This paper studies the current situation of thermal error compensation technology and proposes development countermeasures. The basic principle and importance of thermal error compensation technology and point out the problems of current technology, such as insufficient compensation accuracy and weak real-time. To solve these problems, countermeasures such as optimizing thermal error model, improving sensor layout, adopting efficient data processing algorithm, improving system response speed and developing universal compensation strategy are proposed, and the balance between cost and benefit is discussed. Finally, we summarize the research content and discuss the future development direction and application prospect of thermal error compensation technology, emphasizing the importance of this study to promote the technology development.
