Abstract (en)
[origin: WO2021019024A1] The invention relates to an abrasive flow machining tool (10), comprising a grinding medium driving device (24), which is suitable for moving the grinding medium (14) in a flow direction over a surface of a workpiece (12) and/or through the opening (16) of the workpiece (12), comprising a workpiece holder (18) for holding the workpiece (12) with two parts (20, 22) which are positionable on opposite sides of the workpiece (12), comprising a structure-borne noise sensor (36) for measuring structure-borne noise generated in a workpiece (12) as said workpiece is being machined by a grinding medium (14), and comprising an evaluation unit (38), which is suitable for determining the cutting power of the grinding medium (14) and/or the rate of material removal from the workpiece (12) on the basis of an integral value of the root mean square of the structure-borne noise, measured by the structure-borne noise sensor (36), over time. The invention furthermore relates to a method for determining material removal from a workpiece and to a method for determining the cutting power of a grinding medium.
