For automated batch production with machine tools process monitoring is essential to secure process stability and quality of the product. Referencing the monitoring usually happens during ramp-up of the process by measuring different signals of the machine. In order to provide process monitoring for single part production, reference data has to be generated without having a chance to teach the monitoring with real process data. A way to circumvent this is to use a process simulation of material removal to reference process monitoring. This approach enables calculation of signal-alike reference data based on the NC-path for a workpiece. Hence an autonomous control for manufacturing single parts is possible.

This paper describes a concept to generate reference data for process monitoring via a way-based simulation of the process. For this purpose a method to use a control and machine-based simulation coupled with a dexel-based simulation of material removal is described. The comparison of results of the simulation with measured signals of a real process gives a first validation of the basic concept.
