Thermal Error Modeling and Compensation Method for Spindle of Five-Axis CNC Machine Tools

Full Text(PDF, 28KB)

Author: Dongjun He

Abstract: Thermal errors in CNC machine tools, particularly those involving the spindle, significantly affect machining accuracy and performance. These errors, caused by temperature fluctuations in the spindle and surrounding components, result in dimensional deviations that can lead to poor part quality and reduced precision in high-speed manufacturing processes. This paper explores thermal error modeling and compensation methods for the spindle of five-axis CNC machine tools. A detailed analysis of the heat generation, transfer mechanisms, and finite element analysis (FEA) is presented to develop accurate thermal error models. Compensation techniques, such as model-based methods, sensor-based methods, real-time compensation algorithms, and hybrid approaches, are critically reviewed. This study also discusses the challenges in real-time compensation and the integration of thermal error compensation with machine tool control systems. The objective is to provide a comprehensive understanding of thermal error phenomena and their compensation strategies, ultimately contributing to the enhancement of machining accuracy in advanced manufacturing applications.
