| 摘 要： | 提出一种检测加工中心在高速进给条件下精度的非接触方法.以三轴加工中心为例,介绍了这种方法的数学理论基础.利用两个激光干涉仪分别测出加工空间XY、YZ和XZ平面内的坐标值和半径误差等信息,把这些数据代入已经建立的数学模型中,程序即可自动计算出机床的静态和动态误差.该方法检测时的进给速度是接触法的6倍,更适用于现代高速进给机床的精度检测,而且检测精度比接触法高,检测范围更宽.

| Abstract: | A non-contact precision measuring method of CNC machine tools under the high feed rate condition was put forward.This article introduced the mathematic basis of the method using three-axes machine tools as example.Two laser interferometers are used to measure the displacements and feed speed data along circular interpolation motion individually measured three group data in XY,YZ and XZ work planes,and the space errors of the CNC can be acquired through solving the special mathematic model based on the measurement principle of DBB.The measuring precision of non-contact is more accurate than the (contact's.) |
