摘要 碳纤维增强树脂基复合材料(Carbon fiber reinforced polymer,CFRP)是一种典型的难加工材料,其铣削加工存在表面质量差、表面形貌难以充分表征等问题,为解决该问题,开展了不同进给速度下的槽铣试验,研究了CFRP 铣削表面形貌及其形成机理。结果表明,三维表面粗糙度较二维表面粗糙度能更加全面地反映 CFRP 铣削表面形貌,并选用了算术平均高度 Sa、均方根高度 Sq、偏斜度 Ssk 以及陡峭度 Sku 对 CFRP 表面形貌进行联合表征。随着进给速度的增大,三维表征参数中Sa、Sq逐渐增大,Ssk和Sku逐渐减小。为保证较好的加工表面质量,应选用顺铣的加工方式,且进给速度不大于 1200mm/min。

Abstract:Carbon fiber reinforced polymer (CFRP) is a typical difficult–to–machining material. There are still some problems in its milling process, such as the poor surface quality and difficulty in fully characterizing the surface topography. In this article, slot–milling tests were carried out with different feed speeds, and the surface topography and machining mechanism of CFRP milling was studied. It was found that there was a big deficiency using two–dimensional surface roughness parameters, three–dimensional surface roughness can more comprehensively reflect the surface topography of CFRP milling. The surface topography of CFRP was jointly characterized by arithmetic mean height Sa, root mean square height Sq, skewness Ssk and kurtosis Sku. With the increase of the feed speed, Sa and Sq increase gradually, but Ssk and Sku decrease. In order to guarantee the machined surface quality, the down milling method is used, and the feed speed should be less than 1200mm/min.
