Geometrical Models for Precision Grinding Aspherical Mould
Aspheric optical components are widely used as important parts of commercial optical products owing to their desirable properties. The fast growing demand needs urgently efficient and economical fabrication methods. So this paper discussed systematic geometrical models for programming tool path of precision grinding aspheric mould used in batch production. The integrated geometric models and the corresponding machining parameters, such as suitable radius of tools, tool path interval and linear feed were presented based on precision assurance for lower manufacturing cost and higher production. Therefore, it could also provide a reference for NC control software system in other kinds of aspheric surfaces manufacture.
