Abstract

During the cutting, because of coactions of the workpiece and the tool, an important, plastic shape transformation happens in a slim layer of the workpiece. This strain depends not only on the machining parameters, but on the material-quality too. Locally differing shape transformation can be detected especially in case of materials that own a big extent of anisotropy of mechanical parameters (e.g.: elastic modulus). In such materials the differences of the orientations of crystallites influence the surface roughness, too. In my study the results of examinations were made on OF-Cu and Al samples by an „in situ” (with videocamera) observation of the chip removal, and by the measuring of 1., the shape transformation of the chipped surface and the removed chips, and 2., change of micro hardness. We wanted to know, what effects each parameters of the anisotropy and cutting have on the workpiece’s plastically deformed layers- size and features.
