The aim of this study is to reveal how ZrO₂ (zirconia) contributes to the machinability of aluminum 1050. In the first stage of this study, composite materials were produced by the vortex method by adding different amounts of ZrO₂ (5%, 10%, 20%, and 30%) into commercial aluminum of 99.5% purity. Then, microstructure images of composite materials were taken under the scanning electron microscope (SEM), and the hardness of these composite materials was measured. In the last stage, the machinability tests of the composite materials were performed on the lathe under dry machining conditions at 125, 175, and 225 m/min cutting speeds and 0.03–0.06 and 0.12 mm/rev feed rates, with 1.5 mm constant depth of cut. Uncoated cementite carbide cutting tool inserts were used in machining tests. SEM images of the cutting tool inserts were taken, and the roughness values of the machined surfaces were measured. Chip samples were taken and investigated. It was observed that all the cutting tools had a Built-Up Edge (BUE) formation. Surface roughness and BUE formation increased as the feed rates were increased and decreased with increasing cutting speed. The roughness values decreased slightly and then increased again depending on the ZrO₂ ratio. As the feed rates increased, a transition from ribbon chip type to the helical and saw-toothed forms was observed. It was also observed that the chip formation changed depending on the amount of ZrO₂ in the composite structure.

这项研究的目的是揭示ZrO ₂（氧化锆）如何促进铝1050的可加工性。在这项研究的第一阶段，通过涡旋法通过添加不同量的ZrO ₂来生产复合材料。（5％，10％，20％和30％）制成纯度为99.5％的商品铝。然后，在扫描电子显微镜（SEM）下拍摄复合材料的微观结构图像，并测量这些复合材料的硬度。在最后阶段，在干式加工条件下以125、175和225 m / min的切削速度以及0.03–0.06和0.12 mm / rev的进给速度在1.5 mm恒定深度下在干式加工条件下对复合材料的切削性能进行了测试。切。未涂层的硬质合金硬质合金切削刀片用于机加工测试。拍摄切削刀片的SEM图像，并测量加工表面的粗糙度值。提取芯片样品并进行研究。观察到，所有切削工具均具有“积屑瘤”（BUE）结构。随着进给速度的增加和切削速度的增加，表面粗糙度和BUE的形成也随之增加。粗糙度值根据ZrO略有降低然后再增加₂比率。随着进给速度的增加，观察到从带状切屑类型到螺旋形和锯齿形的过渡。还观察到切屑形成根据复合结构中ZrO ₂的量而变化。
