Abstract A method based on the principle of reverse engineering for fitting the elliptical cylinder component is proposed. At first, the data on the face of elliptical cylinder component is sampled by electronic totalstation,then, the normal vector is gotten by fitting the bottom surface. At last, arbitrary elliptical cylinder is transformed to the standard form by the coordinate transformation. In the way, the elliptical cylinder fitting transforms to the ellipse fitting. At the end, an engineering example is shown to prove the feasibility of this method.
