滚齿机床的误差模型

Error Model of Hobbing Machine

对六轴数控滚齿机进行误差分析,利用齐次坐标转换和坐标旋转的方法,得到六轴滚齿机的误差数学模型。这对于提高滚齿的加工精度、特别是利用目前较热门的数控补偿的方法减小加工误差有着重要的理论和实际意义。

The errors of the six - axis hobbing machine and between two components after the relative linear movement and relative rotative movement were analyzed. With the homogeneous transform and the rotation of coordinates, the math model of the errors of the six - axis was set up. It is very important to improve the gear accuracy, and is effective to decrease machining error by the pop NC compensation technology.
