In this research a formulation by which perpendicularty of motion of vertical milling machine is evaluated, is shown. By using it, an estimation method for perpendicularity of motion between X-, Y- and Z- axis based on the master block measuring is proposed. The proposed method has following characteristics : (1) the perpendicularity of motion X-, Y- and Z- axis is estimated without interference of setting posture of cutting tool, since the geometric error components is derived from driving planes which is calculated by measured points on master block, (2) perpendicularity of motion is estimated without interference of setting errors of master block, since the geometric error components are derived by inner products of normal vectors of driving planes which are indepencdent of coordinate system of machine tools, and (3) since the model of machine tools with geometric errors is constructed of the driving motion and the perpendicularity of motion only, it is more simple to estimate the perpendicularity of motion X-, Y- and Z- axis.

本文给出了立式铣床运动垂直度的计算公式。在此基础上，提出了一种基于主块测量的X、Y、Z轴运动垂直度估计方法。该方法具有以下特点：(1)估算运动X、Y、Z轴的垂直度，不受刀具设置姿态的干扰，因为几何误差分量是由主块上的测量点计算的驱动平面导出的；(2)估算运动垂直度，不受主块设置误差的干扰；由于几何误差分量是由与机床坐标系无关的驱动平面法向量的内积导出的；(3)由于几何误差的机床模型仅由驱动运动和运动的垂直度构成，因此估计运动的X、Y、Z轴垂直度更为简单。
