Abstract

Implementations of a method for determining a degree of dirtiness of a cutting tool that is driven in a back and forth motion by an electric motor include evaluating a parameter that corresponds to the motion of the cutting tool and that is used for controlling the electric motor. The degree of dirtiness is determined based on the parameter.
