METHOD FOR SHAPING A WORKPIECE |
| 摘要 |
The invention relates to a method (31) for shaping a workpiece (2), in which the workpiece (2) is brought into contact with a tool (3) and, lying against the tool (3), is moved at a relative velocity (vR) in relation to the tool (3), wherein the relative velocity (vR) has a constant component (vK) and a changing component (vS). In order to reduce fabricating or shaping forces to be applied, it is provided according to the invention that a ratio of the changing component (vS) to the constant component (vK) is greater than or equal to 0.7. |

1. A method for shaping a workpiece, wherein the workpiece is brought into contact with a tool and, while in contact with the tool, is moved relative to the tool with a relative velocity, wherein the relative velocity has a constant component and a changing component caused by an ultrasonic oscillation, wherein a ratio of the changing component to the constant component is greater than or equal to 0.7, and wherein, in a contact area, where the workpiece is in contact with the tool, the ultrasonic oscillation is a longitudinal oscillation, which extends parallel to the constant component of the relative velocity. |
