Abstract
It is one object of a hale-machining method and apparatus thereof according to the present invention to achieve an easy preparation of an NC machining program and perform a high geometrical accuracy in the predetermined three-dimensional free curved surface. A haling toolis set on a tool holderin such a manner that a cutting point P of the haling toolis substantially coincided with an intersection of a first rotating axis B, a second rotating axis A and a third rotating axis C. A rotary tableand a rotary baseare rotated in such a manner that a tool axis direction of said haling tool is substantially coincided with a normal direction of said machined surface. A tool holderis rotated in such a manner that a front rake surface of the haling toolis substantially directed in perpendicular to a feeding direction of said haling tool. A workpiece table holding a workpiece and the tool holder are relatively moved along a machined surface of said workpiece in three perpendicular axes including an axis parallel to said first rotating axis.
