A method of disposing a flexible jig with respect to a CNC machine

A method for correctly positioning a flexible fixture (20, 120) with respect to a CNC machine (10, 110), comprising: Placing a flexible fixture (20, 120) to a table (12, 112) of the CNC machine (10, 110); Examining several Fixieraufnahmen (30, 32, 34, 130, 132, 134) on the flexible clamping device (20, 120), wherein a Fixieraufnahmeposition in a coordinate system of the CNC machine (10, 110) for each of Fixieraufnahmen (30, 32, 34, 130, 132, 134) is determined; Determining whether each of the plurality Fixieraufnahmen is within a predetermined offset margin of a predetermined nominal position; and electronic compensating the error of the determined by examining Fixieraufnahmepositionen compared to the predetermined nominal positions when all of the plurality Fixieraufnahmen (30, 32, 34, 130, 132, 134) are located within the predetermined displacement boundary.
