free-form surface modeling

基本解释

Meanwhile, it is required that the free-form surface modeling must be able to change the freedom of local and meet all kinds of design requirements.
同时，要求自由曲面的造型必需能够局部地自由加以变更，使其符合各式设计需求。
Basic theory and procedure of NC machining for free-form surface based on reverse engineering were introduced. Digital measure and CAD modeling as well as tool path generating were analyzed.
介绍了以反求工程为技术支撑的自由曲面数控加工的基本原理和全过程，并对其中的数字化扫描、 CAD 建模及刀具轨迹生成等关键技术作了进一步的分析。
With the development of modeling technology of free-form surfaces, the product with free-form surface is widely used in the modern life and the true production.
随着自由曲面造型技术的深入发展，含有自由曲面形状特征的产品在现代生活、生产中的应用也越来越广泛，对自由曲面加工的相关问题研究也日愈深入。
