Adhesion wear is the main wear mechanism in the dry turning of aluminium alloys. This type of wear produces an adhesion of the machining material on the cutting tool, decreasing the final surface quality of the machining parts and making it more difficult to maintain industrial tolerances. This work studies the influence of the cutting parameters on the volume of material adhered to the cutting tool surface for dry machining of AA2024 (Al-Cu). For that purpose, a specific methodology based on the automatic image processing method that can obtain the area and the thickness of the adhered material has been designed. This methodology has been verified with the results obtained through 3D analysis techniques and compared with the adhered volume. The results provided experimental parametric models for this wear mechanism. These models are analytic approximations of experimental data. The feed rate mainly results in low cutting speed, while low depths of cut presents a different behaviour due to the low contact pressure. The unstable behaviour of aluminium adhesion on the cutting tool produces a high variability of results. This continuous change introduces variation in the process caused by the continuous change of the cutting tool geometry.
粘着磨损是铝合金干式车削中的主要磨损机制。这种磨损类型会使加工材料粘附在切削刀具上，降低加工零件的最终表面质量，并使保持工业公差变得更加困难。本文研究了切削参数对AA2024（铝铜合金）干式加工中粘附在切削刀具表面的材料体积的影响。为此，设计了一种基于自动图像处理方法的特定方法，该方法可以获取粘附材料的面积和厚度。该方法已通过三维分析技术获得的结果进行了验证，并与粘附体积进行了比较。结果为此磨损机制提供了实验参数模型。这些模型是实验数据的解析近似。进给率主要导致切削速度较低，而切削深度较小时，由于接触压力较低，表现出不同的行为。铝在切削刀具上的粘附不稳定行为导致结果的高变异性。这种持续变化会因切削刀具几何形状的持续变化而在加工过程中引入变化。
