摘　　要：数控机床热误差自动检测节点的设定通常具有区域性,检测范围较小,导致自动检测频次变低。为此,提出基于多传感器的数控机床热误差自动检测方法。根据自动检测需求,采用多点位的方式扩大检测范围,部署多点位传感节点部,建立数控机床热误差检测结构。以此为基础,构建多传感器的数控机床热误差自动检测模型,采用热误差补偿处理来实现自动检测。测试结果显示,随机选择3个测试阶段,针对4个选定的基础测点,通过对比计算获得的自动检测频次可达15次以上,这说明在多传感器技术的辅助与支持下,设计的数控机床热误差自动检测方法更加灵敏、高效、可控。同时,其自身还具有较强的稳定性和针对性,应用效果显著提升,具有实际的应用价值。The current setting of automatic detection nodes for thermal errors in CNC machine tools is generally regional,with a small detection range,resulting in a decrease in automatic detection frequency.Therefore,a multi-sensor based automatic detection method for thermal errors in CNC machine tools is proposed.According to the requirements of automatic detection,a multi-point approach is adopted to expand the detection range,deploy multi-point sensing nodes,and establish a thermal error detection structure for CNC machine tools.Based on this,a multi-sensor automatic detection model for thermal errors in CNC machine tools was constructed,and thermal error compensation processing was used to achieve automatic detection.The test results showed that randomly selecting three testing stages and targeting the four selected basic measurement points,the automatic detection frequency obtained through comparative calculation could reach more than 15 times.This indicates that with the assistance and support of multi-sensor technology,the designed automatic detection method for thermal errors in CNC machine tools is more sensitive,efficient,and controllable.At the same time,it also has strong stability and pertinence,significantly improving its application effect and having practical application value.
