Abstract

Surface quality is an essential requisite in the manufacturing industry. In order to perform an in-depth study into the mechanisms that govern the formation of this surface, all factors involved in the machining process must be ascertained. The resulting surface after turning (real surface) is studied as the superposition of multiple surfaces. A first surface, (tool surface), is generated from the geometry of the tool and machining parameters. A second surface (vibration surface) is generated from the vibration of the tool. Finally, a third surface (other-factors surface) is taken as the joint result of fracture of material, elastic recoveries, plastic deformations, hardness, kinematic, deposits and/or adhesions of material and/or tool wear. The comparison of these four surfaces enables this objective to be reached. A new parameter denominated dispersion is defined. Principal component analysis (PCA) is used in the definition of this parameter.

三维曲面生成过程中的表面更改。通过车削加工的情况。主成分分析在各种因素研究中的应用

在制造业中，表面质量是必不可少的。为了对控制该表面形成的机制进行深入研究，必须确定加工过程中涉及的所有因素。车削后得到的曲面(实曲面)是多个曲面的叠加。第一个表面(刀具表面)是由刀具的几何形状和加工参数生成的。由刀具的振动产生第二曲面(振动曲面)。最后，第三个表面(其他因素表面)被认为是材料断裂、弹性恢复、塑性变形、硬度、运动学、沉积和/或材料和/或工具磨损的联合结果。这四个表面的比较使这一目标得以实现。定义了一个名为色散的新参数。主成分分析(PCA)用于该参数的定义。
