摘要 |
<p>Device for cutting off a workpiece, with a periodically moving tool holder (1), at least one blade-like tool (2), a tool support, and a drive (4) acting on the tool holder (1). The drive (4) imparts a rocking motion with parallelogram-link kinematics and a predetermined oscillation radius to the tool holder (1). The tool (2) has a non-rectilinear cutting edge (6) which produces a cutting-off gap in the workpiece and generates in the cutting-off gap a base surface corresponding to the width of the cutting-off gap and having a predetermined cut contour (7). The cutting edge (6) is constructed in a circular arc shape with a circular-arc radius Rb and generates a circular-arc cut contour (7) with the cut-contour radius Rw. Rb is greater or less than Rw. The oscillation radius Rs is selected such that working contact in the form of quasi-point contact takes place between the cutting edge (6) and the cut contour (7). …<IMAGE>… </p> |
