Claim One:
1. A method to assure quality when operating an industrial machine for processing a work-piece, comprising: storing simulation results from a material erosion simulation of at least part of an operation of an industrial machine based on a simulation model wherein the simulation results comprise setpoint values for quality assurance simulated at each of a plurality of processing steps; receiving real data from the operation of the industrial machine from measurements of the work-piece taken by a measuring program at each of a plurality of processing steps during the processing of the work-piece; comparing the simulation results and the real data from the operation of the industrial machine at each of the plurality of processing steps during the processing of the work-piece to check whether at each processing step the setpoint values compared to the real data are within a permitted tolerance range based on a geometric deviation from the setpoint values; interrupting the operation of the industrial machine and automatically rejecting the work-piece based upon a result of comparison of the simulation results and the real data at a particular processing step during the processing of the work-piece in which the result of the comparison is outside the permitted tolerance range indicating a fault, thereby avoiding further processing steps being continued if the fault is detected; assigning the detected fault to the particular processing step for which the fault is detected to identify a specific source of the fault for fault analysis; and scrapping or re-working the rejected work-piece at the particular processing step depending on a severity of the detected fault.
