摘要:
在综合介绍目前反求工程的 CAD建模技术的基础上,提出一种实用的基于实物样件获取产品数学模型的 CAD建模技术 .结合对实际工业产品的反求过程,全面介绍了该技术中的表面数字化、散乱数据误差修正、散乱数据规则化、曲面重构、CAD建模等过程的技术要点 .应用结果表明 :该 CAD建模技术实用,有效,能够有效避免产品反求过程中曲面畸变、干涉等变形的产生,生成的数学模型光滑、连续、几何信息完整; 在数控加工和反求工程中有着广阔的应用前景,是推行并行工程的重要基础和支撑技术 .同时,由于该技术的实施能在很短的时间内复制实物样件,因此在实际应用中具有广为推广应用的价值 .
Abstract:
The CAD modeling technique in reverse engineering at present is surveyed. On this basis,the authors present a practical one which acquires mathematical model of product based on exemplar of material object. Combining with reverse process of actual industrial producls,a comprehensive account is made on the technical main points of such processes as surface digitalization, error-correcting of debunching data,regularization of debunching data,reconstitution of camber,and CAD modeling. As indicated by results from application,this is a practical and effective CAD modeling technique by which the emergence of such deformation as distortion of curved surface and interference can be avoided and a smooth and continuous mathematical model with complete geometric information can be generated. This technique has a broad prospect of applicaion in NC machining and reverse engineering,it is important basis and proping up techingue for carrying out concurrent engineering. Moreover,the exemplar of material object can be duplicated within very short time owing to its practice,this technique has the value of widely application.
