This study was carried out for 2 years, and three systems : a diagnosis system for motion accuracy of a machine tool, a diagnosis system for the main spindle of a machine tool, and a remote diagnosis system of a machine tool by utilizing a network, have been developed. The results are summarized as follows :1. A diagnosis system for motion accuracy of a machine toolA method to test motion and positioning accuracy of an NC machine tool is proposed and a device and a system to measure and diagnose the accuracy are developed. The device has the measurement resolution of 1 mm by using the laser interferometer. It was confirmed that the device with two measurement axes could measure the locus such as circular motion and perpendicular motion.2. A diagnosis system for the main spindle of a machine toolAn acceleration sensor, an AE sensor, and a thermo-sensor are installed by the main spindle of a machine tool. A system is developed to diagnose the damage of the main spindle of a machine tool by extracting the features representing damage of the main from the sensor signals and identifying the feature with the damage.3. A remote diagnosis system of a machine tool by utilizing a networkThe mutual communication system between a host computer and the controller of an NC machine tool was developed. Using the system enable one to operate a machine tool by remote control from the host computer side and to obtain and modify the NC parameter from a remote place. In addition, signals from the sensor installed in a machine tool are transferred to the remote host computer through the network. A remote diagnosis system of a machine tool was developed by using the mutual communication system.

本研究历时2年，开发了机床运动精度诊断系统、机床主轴诊断系统和利用网络的机床远程诊断系统3个系统。研究结果总结如下：1。提出了一种检测数控机床运动和定位精度的方法，研制了一种测量和诊断机床运动和定位精度的装置和系统。采用激光干涉仪，测量分辨率为1mm。实验结果表明，该装置具有两个测量轴，可以测量圆周运动和垂直运动等轨迹。一种机床主轴诊断系统，在机床主轴上安装加速度传感器、声发射传感器和热传感器。通过从传感器信号中提取代表主轴损伤的特征，并将特征与损伤进行识别，开发了机床主轴损伤诊断系统。介绍了一种基于网络的数控机床远程诊断系统，开发了数控机床上位机与控制器之间的互通信系统。利用该系统，可以从上位机端远程操作机床，并可以远程获取和修改数控参数。另外，安装在机床上的传感器发出的信号通过网络传输到远程主机。利用双向通信系统，开发了机床远程诊断系统。
