【摘要】：超声辅助磨削是一种适于加工陶瓷等硬脆材料的先进复合加工技术。在超声振动方向垂直于加工表面的条件下,采用金刚石杯形砂轮对碳化硅陶瓷进行超声辅助磨削与普通磨削试验。对两种方法的磨削力、力比及加工表面粗糙度进行了对比分析,并讨论了磨削用量变化对两种方法在上述指标中差异程度的影响。结果表明,与普通磨削相比,超声辅助磨削可显著降低磨削力,但一定程度上将导致加工表面质量变差。随着磨削用量的增大,超声辅助磨削与普通磨削之间的差异逐渐减弱,超声辅助磨削效果逐渐消失。
[Abstract]:Ultrasonic assisted grinding is an advanced composite machining technology suitable for machining hard and brittle materials such as ceramics. Under the condition that ultrasonic vibration direction is perpendicular to the machined surface, The experiments of ultrasonic assisted grinding and common grinding of silicon carbide ceramics with diamond cup wheel were carried out. The grinding force, force ratio and surface roughness of the two methods were compared and analyzed. The effects of grinding parameters on the degree of difference between the two methods are discussed. The results show that ultrasonic assisted grinding can significantly reduce the grinding force compared with ordinary grinding. However, to some extent, the quality of machined surface will become worse. With the increase of grinding amount, the difference between ultrasonic assisted grinding and ordinary grinding is gradually weakened, and the effect of ultrasonic assisted grinding is gradually disappeared.
