Abstract
It is known that vibratory OD-blade slicing, which involves the application of a low-frequency vibration to an OD-blade or a workpiece, exhibits the self-corrective effect of the OD-blade owing to the intermittent repetition of contact and separation between the OD-blade and the workpiece. Moreover, in our previous study, we investigated the mechanism of the self-corrective effect using dynamic numerical simulation, and it was shown that this effect can reduce the blade elastic deformation during slicing and the waviness of the sliced surface. In this paper, we discuss this effect using finite element method (FEM) simulation, and show the dynamical results of blade elastic deformation during vibratory slicing. Furthermore, in this paper, we describe slicing accuracy characteristics, such as the waviness, roughness and sawing marks of the sliced surface obtained experimentally. It is found that the waviness and generation rate of sawing marks on the sliced surface in vibratory slicing are not only reduced compared with those in non-vibratory slicing owing to the OD-blade self-corrective effect brought about by vibration, but also the roughness distribution is not changed between non-vibratory and vibratory slicing, on the basis of a series of experimental and FEM simulation analyses.
