    • Method of preparing NC data for moving a working head (WHD) along a path (PT) which is a predetermined distance D away from a curved surface (CS). Coordinate values (x, y, z) representing the position of the center (QO) of rotation of the working head (WHD) are obtained at the time when the tip of the working head (WHD) is located at a point (PO) on the curved surface (CS). Further, unit components (i, j, k) of the vector (BR) of the central axis of the working head (WHD) are obtained at the time when the tip of the working head (WHD) is located at the point (PO). By the use of the positional coordinate values and the unit components of the central axis vector as well as the distance D between the curved surface (CS) and the tip of the working head (WHD) during an operation, which is given separately, positional control data (X, Y, Z) for moving the working head (WHD) along the path (PT) which is away from the curved surface (CS) by the distance D are obtained from the following formulae: X = x + i x D; Y = y + j x D, Z = z + k x D. By the use of the positional control data thus obtained, NC data for controlling the position of the working head is prepared.
    • 准备NC数据的方法,该数据用于沿着距离弯曲表面(CS)预定距离D的路径(PT)移动工作头(WHD)。 在工作头(WHD)的尖端位于点(PO)处时,获得表示工作头(WHD)的旋转中心位置(QO)的坐标值(x,y,z) 在曲面(CS)上。 此外,在工作头(WHD)的末端位于点(PO)处时,获得工作头的中心轴线(WHD)的矢量(BR)的单位分量(i,j,k) )。 通过使用单独给出的操作期间的中心轴矢量的位置坐标值和单位分量以及曲面(CS)和工作头(WHD)的尖端之间的距离D, 用于使离开曲面(CS)的路径(PT)的工作头(WHD)移动距离D的控制数据(X,Y,Z)从以下公式获得:X = x + ix D ; Y = y + j×D,Z = z + k×D。通过使用如此获得的位置控制数据,准备用于控制工作头位置的NC数据。
