摘要
以极坐标数控铣、滚齿复合机床为研究对象,利用空间直角坐标系和空间极坐标系建立了机床整机几何误差模型,并得出简化计算模型。利用建立的几何误差模型,可以准确计算出机床的几何误差,为机床误差补偿提供了理论依据。
Using the rectangular coordinates system and the polar coordinates system, the complicating NC machine-tool from polar-coordinate milling and bobbing was taken as the research object to establish the geometrical error model of the machine-tool. Using this error model, the geometrical error of machine-tool can be calculated accurately, which offers a theory foundation for analyzing the error of it.
