摘要
光学玻璃、功能晶体、工程陶瓷等硬脆材料具有高强度、耐高温、耐磨损等优良的物理和机械性能,目前已被广泛应用于航空航天、汽车、军工等领域.但由于这些材料具有较高的硬度和脆性,难以用传统的加工方法进行加工,从而在很大程度上制约了这些材料的进一步推广和应用.旋转超声辅助加工技术由于其特殊的加工性能,具有切削力小、低切削热等优点,适应于各种硬脆材料的加工,因此得到了广泛的应用和迅速的发展,在硬脆难加工材料的制造领域已经占据了重要的地位.本文回顾了旋转超声辅助加工技术的发展历程和特点,介绍了旋转超声辅助加工的机理及工艺设备的研究进展,并对旋转超声辅助加工技术和设备的发展趋势进行了展望.
Hard and brittle materials, such as optical glass, functional crystal and ceramics, enjoy such advantages as high strength, resistance to elevated temperatures, withstanding wearing and tearing, etc. They have been, therefore, widely applied to the fields of aviation, automobile and military industries, etc. Because of their good performance in hardness and brittleness, it is quite difficult and inefficient to machine them using traditional methods. As a result, their application is limited. As one of the non-con- ventional machining methods, rotary ultrasonic machining（RUM） is an effective way for machining hard and brittle materials. With the advantages of less cutting force and less cutting heat, RUM can be applied to almost all hard and brittle materials. Therefore, RUM has been used widely and it develops quickly. After decades of development, it has taken an important part in manufacturing hard and brittle materials. In this paper, the RUM history and its characteristics were introduced firstly, and then the development of RUM equipment and research on machining mechanism and process were presented. Finally, the de- velopment tendency was summarized.
