Modeling of Process Machine Interactions in Tool Grinding

A systematic modeling approach to predict and manipulate the static and dynamic process machine interactions in tool grinding is described. The modeling approach is verified by experimental investigations gained by means of an industrial tool grinding machine and separate test stands. It combines models of the static and dynamic behavior of the grinding machine and its components with a microscopic grinding process model. Material removal algorithms are applied to cope with the changing shape and changing mechanical properties of the workpiece during grinding. The interaction model has been applied in the process planning phase to optimize tool paths and process parameters in order to reduce resulting shape errors in ground tools.
