Method and system for protecting execution data and/or processing data of a machine tool

Abstract

The present invention relates to a method and a system for providing processing data to a numerically controlled machine tool (100), comprising: providing processing data (S301) to a data processing device (300), wherein the processing data comprises numeric control data, in particular one or more NC programs, on the basis of which a processing of a workpiece on the numerically controlled machine tool (100) can be carried out; specifying encryption specifications (S302) on the data processing device (300), which indicate specifications for encrypting the processing data and/or the execution data; specifying authentication specifications (S303) on the data processing device (300), which indicate specifications for authentication of the numerical machine tool and/or of an operator of the machine tool; specifying execution specifications (S304) on the data processing device (300), which indicate specifications for the machining of the workpiece on the numerically controlled machine tool; generating execution data (S305) on the basis of the specified execution specifications, wherein the execution data comprises the processing data; and encrypting the execution data (S306) on the basis of the encryption specifications; providing or transmitting (S307) the generated execution data to a control device (200, 300) of the numerically controlled machine tool (100).
