摘　　要：针对开发的误差实时补偿控制器,通过利用温度传感器对双转台五轴机床温度场进行分析,并用位移传感器测量五轴机床的刀具相对于工作台在x、y、z方向上的热误差。利用开发的机床位移通讯接口系统建立补偿控制器与机床CNC系统通讯接口的连接,从而能够使机床的位移信号实时传入补偿控制器,在已经确立的敏感热源点安装补偿用温度传感器,并通过温度采集系统建立温度传感器与补偿控制器的连接,实现温度信号引入补偿控制器,能进行机床温度、主轴在3个方向上的热误差手动和自动测量,让测量数据和模型输出结果进行比较,预报模型的残差比较小,补偿效果较好。The development of Real time error compensation controller can detect and identify the temperature field of five axis machine tool with double turntable by using temperature sensor.It can also measure the thermal error of the tool in the directions of x、 y and z relative to the worktable by the displacement sensor. The communication interface between compensation controller and CNC system of machine tool is established by using the developed communication interface system of machine tool displacement. So the displacement signal of the machine tool can be transmitted to the compensation controller in real time and the temperature sensor for compensation is installed at the established sensitive heat source point.The connection between temperature sensor and compensation controller is established by the temperature acquisition system. The temperature signal is introduced into the compensation controller, which can measure the temperature of machine tool and thermal error of spindle in three directions manually and automatically. Compared the measured data with the model output, the residual error of prediction model is small. The compensation effect is better.
