| Research Abstract |
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.
