摘要
根据三维编织碳纤维复合材料非均质性和各向异性的特点,将其车削加工表面分为四类典型表面。分别采用三种不同刀具对三维编织碳纤维复合材料进行了超声辅助车削和普通车削加工试验,分析了四类典型表面的粗糙度的变化规律,建立了三维编织碳纤维复合材料表面质量评价方案,并对超声辅助车削和普通车削加工过程中的切削力和刀具磨损进行了研究。结果表明,超声辅助车削加工三维编织碳纤维复合材料相对于普通车削,可以有效地提高工件表面质量,降低切削力,延长刀具寿命。
Based on the inhomogeneous and anisotropic nature of three-dimensional woven carbon fiber composite, the turning surface is classified to four kinds of typical surface. Three-dimensional woven carbon fiber composite was machined by ultrasonic assisted turning and common turning with three different cutters. The evaluation method of surface quality was established by investigating the surface roughness variation law of four kinds of typical surface. Cut- ting force and tool wear in the ultrasonic assisted turning and common turning were studied. The resuhs show that ul- trasonic assisted turning can effectively improve surface quality, decrease cutting force and prolong tool life as contras- ted with common turning when machining three-dimensional woven carbon fiber composite.
