Abstract
At least two parameters (.delta., Inst) of which it is known that their variation influences the state of the spark erosion process (F, W) are fed to a logic device (5) in which a set of rules is stored. The logic device processes the parameters fed with the aid of the stored rules according to the laws of fuzzy logic, and generates at least one output signal (.epsilon.) which is fed to a controller (6) of at least one parameter, in order to match or at least approximate the currently prevailing state of the spark erosion process to a currently desired state of the spark erosion process.
