Title: METHOD AND DEVICE FOR THE INCREMENTAL FORMING OF A METALLIC WORKPIECE
Abstract:
The invention relates to a method and a device for the incremental forming of a metallic workpiece, comprising at least one spindle, on which the workpiece is clamped, and at least one spindle drive, with which the at least one spindle with the workpiece and/or at least one forming roller is set in rotation in relation to the workpiece, wherein the at least one forming roller is infed radially and/or axially in relation to the rotating workpiece by means of at least one actuating drive. The invention provides that there is a computer-based controller that uses sensors to detect multiple machine parameters, which comprise at least one rotational speed of the spindle, a position of the forming roller and forming forces and/or an infeed rate of the forming roller, that process parameters and/or workpiece parameters are also detected by the controller and that the controller creates at least one data record, in which the machine parameters are assigned to the process and/or workpiece parameters.
