Abstract
A description is given of a process and a device for determining the surface structure of metal workpieces cut using a face milling cutter in particular. According to the invention, a characteristic feature of this method is that a variable generated by the machine tool is measured and that the maximum and minimum values of this variable which occur within a specific period of time are defined; to ascertain the surface structure of the workpiece during the machining process, the recorded maximum and minimum values are compared with comparison values correlated with the location of each workpiece; these comparison values, allocated to a specific surface structure of comparable workpieces, are previously recorded and stored.
