复杂曲面加工技术的研究现状与发展趋势

Current Research and Development Trends of Complex Surface Machining Technology

随着高新技术的发展,复杂曲面的应用也越来越广泛,其应用主要取决于两个方面:一方面是力学特性和功能的需要,使设备满足特定的性能要求,这就要求产品形面达到高精度的数学特征;另一方面是外观美学效果的需要,满足人们对产品外形的需求。复杂曲面的发展和实现,又取决于复杂曲面的设计技术和制造技术。从3个方面分别阐述它们的研究现状与发展趋势:复杂曲面设计技术,如曲面造型设计技术、反求技术;复杂曲面加工技术,如光学自由曲面加工技术、复杂刀具加工技术;复杂曲面加工设备,如功能部件、控制系统等。指出复杂曲面设计技术、加工技术及加工设备发展存在的主要问题,对其发展趋势进行科学预测。

With the development of high-tech,applications of complex surface are more and more extensive. Its applications primarily depend on two aspects： on the one hand,requirements of mechanical properties,functions and devices with specific performance,which requires products to achieve high-precision mathematical characteristics;on the other hand,it is the need for aesthetic appearance to meet the demand for product. Development and implementation of complex surface depend on complex surface design and manufacturing technologies. Three aspects on research and development trends are described： Design technology of complex surface,such as surface modeling and reverse engineering;machining technology of complex surface,such as optical free-form surfaces and complex machining;machining equipment of complex surface,such as function parts and control system. The main problems in the development of complex surface design techniques,processing technology and machining equipment are pointed out,and their development trend is forecasted.
