自由菲涅耳曲面、用于生产自由菲涅耳曲面的方法以及用于创建构造数据集的方法
Abstract:
本发明涉及一种用于生产自由菲涅耳曲面的方法，所述自由菲涅耳曲面具有多个菲涅耳小面(12)，所述菲涅耳小面具有相应的菲涅耳段面(10)和后缘(28)。在所述方法中，基于自由菲涅耳曲面的构造数据，通过对基体进行机加工来生产自由菲涅耳曲面。借助于圆柱面和/或锥面，菲涅耳小面的边缘在x-y平面上的投影表示用于创建结构数据的圆形路径。
Abstract(English):

The invention relates to a method for producing a freeform fresnel surface having a number of fresnel facets (12) with a respective fresnel segment surface (10) and a trailing edge (28). In the method, the production of the freeform fresnel surface occurs by means of machining processing of a starting body based on the construction data for the freeform fresnel surface. With the aid of the circular cylinder casing surfaces and/or cone casing surfaces, the projection of the edges of the fresnel facets on the x-y-plane represent circular paths for the creation of the construction data.
