| 摘要 |
The invention relates to a method of measuring a workpiece in a press brake. The invention further relates to a measuring device, a measuring carriage as well as a press brake. The workpiece (8) is measured by the measuring device (16) which is moved in its longitudinal direction (A) during measurement. The measuring device is provided with a supporting arm (29) in which a measuring carriage (30) is arranged by means of a joint (31). The measuring carriage is provided with contact members (41) which follow a surface of the workpiece during the measurement. A position of the measuring carriage with respect to the supporting arm is determined by means of a measuring member (40), and measurement data is used for determining deformation of the workpiece and for controlling operation of the press brake (1). |
