| 摘 要： | 硬脆材料具有高强度、高硬度、低密度等特点，用传统方式加工时损伤大、效率低，而超声辅助磨削具有磨削力小、加工质量优等优点，在硬脆材料加工领域具有独特优势。从不同振动维数及振动方向与磨削表面位置关系的角度出发，总结了不同类型超声辅助磨削加工的机理及特性，在此基础上探讨了硬脆材料超声辅助磨削的延性域加工机理、超声振动参数与磨削用量匹配性的研究现状，并对今后超声辅助磨削领域应重点关注的研究方向进行了展望。

| Abstract: | Hard and brittle materials have some significant characteristics such as high strength,high hardness and low density.However,just because of high hardness and brittleness,great damage and low efficiency are the dramatic problems for these materials when processed by traditional methods.By contrast,ultrasonic assisted grinding(UAG)possesses some advantages such as lower grinding force and better processing quality.These characteristics bring particular advantages for machining hard and brittle materials.Considering different vibration dimensions and location positions between vibration direction and grinding surface,grinding mechanisms and performances of different kinds of UAG are summarized.On the base of these analysis,study of ductile-regime grinding mechanisms,matching performance between ultrasonic vibration and grinding parameters are discussed for UAG of hard and brittle materials.In addition,future prospect about research areas worth paying more attention to during UAG is analyzed. |
