    • An arrangement for removing excess material from an object surface, to provide a desired finished surface. Holes are drilled into the object so that the bottoms of the holes lie on the desired finished surface. The holes have a shape so that the observed hole diameter at the prevailing surface of the object is dependent on the hole depth and thereby dependent on the amount of material remaining to be removed between the prevailing surface and the desired finished surface. The prevailing surface is continuously observed and measured, and the depths of material to be removed in a sequence of steps is calculated dependent on the measurements of the prevailing surface and the coordinates of the desired finished surface. As a result of the calculations, the depth of material removed during each step is controlled, so that upon carrying out a sequence of such steps, the surface exposed on the object after the last step has been carried out, coincides with the desired finished surface. The accuracy of the material removal equipment may be substantially less than the accuracy of the finished surface. Grooves instead of circular holes are cut when the radius of curvature of both the prevailing and desired surfaces becomes sufficiently small, so as to provide sufficient definition of the desired surface. With the grooves, the observed parameter is groove width rather than hole diameter.
    • 用于从物体表面去除多余材料的装置,以提供所需的成品表面。 将孔钻入物体中,使得孔的底部位于所需的成品表面上。 这些孔具有这样的形状,使得在物体的主要表面处观察到的孔直径取决于孔深度,并且因此取决于在主要表面和期望的成品表面之间剩余的待除去的材料的量。 连续地观察和测量主要表面,并且根据主要表面的测量和所需成品表面的坐标来计算要按顺序排列的材料的深度。 作为计算的结果,控制在每个步骤期间去除的材料的深度,使得在执行一系列这样的步骤时,在最后一步之后暴露在物体上的表面已经被执行,与期望的成品表面重合 。 材料去除设备的精度可以显着小于成品表面的精度。 当主流和期望的表面的曲率半径变得足够小时,切割代替圆形孔的凹槽,以便提供所需表面的足够的定义。 对于凹槽,观察到的参数是凹槽宽度而不是孔直径。
