Data-dependent systems approachto surface generation in grinding
This paper initiates a new approach to the analysis of surface generation, by fitting mathematical models to wheel and work surfaceprofiles under actual grinding conditions. Data Dependent Systems (DDS) methodology has been used to model work surface profiles in the longitudinal (across the width of cut) and transverse [along the directionof feed) directions, and the wheel profile along the longitudinal direction. A model for the “characteristic grain” consistingof the superimposition of a large and small wavelength is used to provide an indication about the grain-wear and surface roughness. The large wavelength representing the grain has been used in establishing the deflection ofthe grain. Due to the elastic deflection, the small wavelength representing the cutting edges cuts a smaller groove, which provides a prediction of the rms value of the ground surface in the transverse direction. From the wavelength decomposition of longitudinal profiles, the superimposition of components due to topography of the wheeland kinematic conditions have been identified. The mechanism that leads to such a superimposition is analyzed. Experimental verification of the theory and predictions is given. © 1984 by ASME.
