摘要
为了提高数控机床精度,通过分布在数控机床的温度传感器采集机床各关键点的温度,通过激光干涉仪采集机床相对应的热误差。计算机将采集的温度和热误差数据进行处理后,构造支持向量机模型,并将模型嵌入ARM11开发板中。建立以ARM11开发板为核心的热误差补偿实验平台,以西门子机床的工作平台为实验对象,仿真实验表明该实验平台的可行性和良好的补偿效果。
In order to improve the machining accuracy of CNC, some temperature sensors are used by acquiring key point temperature of machine tool, laser interferometer is used to acquire thermal error. Computer is used to collect the data of the key point temperature and thermal error. SVM model is built and embedded in ARM 11 development boards. Thermal error compensation is established based on ARM 11 development board as the experiment platform and the Siemens machine platform for subjects. Simulation result proves the feasibility and the better compensation’s effect of the experiment platform.
