摘要
高速数控机床在长时间高负载运行中易产生主轴热误差,影响加工精度与系统稳定性。研究主轴热误差的温升特性与空间分布规律,构件基于支持向量回归(Support Vector Regression,SVR)的热误差预测模型,设计补偿系统的软硬件架构以及动态补偿指令的生成机制。研究结果可为主轴热误差的实时控制提供技术路径,对提升高精度加工设备的热稳定性与误差自适应补偿能力具有参考价值。
High-speed computer numerical control machine tools are prone to spindle thermal errors during long-term highload operation,which affects the machining accuracy and system stability.The temperature rise characteristics and spatial distribution law of the thermal error of the main shaft are studied.The component is based on the thermal error prediction model of Support Vector Regression(SVR),and the software and hardware architecture of the compensation system and the generation mechanism of dynamic compensation instructions are designed.The research results can provide a technical path for the realtime control of the thermal error of the spindle and have reference value for improving the thermal stability and error adaptive compensation ability of high-precision processing equipment.
