Abstract
An abrasive flow machine is indicated, having a media drive device which is adapted to move the abrasive medium over a surface of a workpiece and/or through the opening of the workpiece in a flow direction, having a workpiece holder for mounting the workpiece with two parts adapted to be positioned on opposite sides of the workpiece, having a structure-borne sound sensor for measuring structure-borne sound generated in a workpiece when the latter is machined with an abrasive medium, and having an evaluation unit which is adapted to infer a cutting power of the abrasive medium and/or a rate of material removal on the workpiece based on an integrated measurand of the root mean square of the structure-borne sound measured by the structure-borne sound sensor over time. Further indicated are a method of ascertaining a material removal on a workpiece and a method of determining the cutting power of an abrasive medium.
