    • A three-dimensional surface shape is produced from input numerical data. The shape of an elastic surface is determined by the positions of a first matrix of memory rods. The position of each of the memory rods is determined by a flexible sheet which is contoured by a second matrix of control rods and is computer-controlled. After control rods transfer the contour data to the memory rods, the control rods are reset to receive new contour data. Both the memory rod and control rod are fitted with two pneumatically controlled locking mechanisms, one for the X-coordinate and one for the Y-coordinate. When both locks on a particular rod are released the rod is free to move to a new position determined by an elevator. Once all of the rods have been adjusted, they are locked in position and the surface has been configured.
    • 从输入数值数据生成三维表面形状。 弹性表面的形状由记忆棒的第一矩阵的位置决定。 每个记忆棒的位置由柔性片确定,该柔性片由第二控制棒矩阵构成,并由计算机控制。 在控制杆将轮廓数据传送到记忆棒之后,控制杆被复位以接收新的轮廓数据。 记忆棒和控制杆都配有两个气动控制的锁定机构,一个用于X坐标,一个用于Y坐标。 当特定杆上的两个锁都被释放时,杆自由移动到由电梯确定的新位置。 一旦所有的杆已被调整,它们被锁定在适当的位置并且表面已被配置。
