Determining cutting force parameters by applying a system function

For the development of a general cutting force model, cutting forces at various cutting parameters have to be known. Therefore, influences arising from the test setup or data processing have to be eliminated without alteration of the results by also removing influences arising from the examined disintegration process. For wood cutting processes, these disturbing influences arising from the test setup have not been yet of great concern. So far, applied methods for elimination of disturbing influences were not able to distinguish between influences arising by the setup or by the workpiece leading to faulty results. Within the following work, a method for the characterization of test setups is presented, enabling a correction method of different examinations. The following approach is based on applying the system function known from control engineering enabling a correction method for elimination of influences arising from the setup and from data processing by the identification of transmission characteristics of the test setup. Subsequently, the identified transmission characteristic is used for the correction of own cutting force measurements. Based on these results consequences by neglecting the specific transmission characteristics are discussed.
