Abstract
The method of and a device for using this method, on equipment or assigned to equipment for working a material, for investigating and identifying the nature of the material, which is to be worked and for making available at least one operating parameter for the optimized pre-setting of the working equipment, provides for the use of a sensor, preferably assigned directly to the working tool, such as a hammer drill, in order to detect shock waves generated or induced in the tool. From the shock wave signal measured, at least one distinguishing feature characteristic of the material to be worked, is extracted and evaluated for the comparative classification of the material by means of an algorithm. Preferably, an external force, especially the contacting force, acting on the working equipment, is taken into consideration for the algorithmic evaluation.
