Abstract
A grinding process model based on a kinematic modeling approach is presented. A unique experimental set-up is designed for validation purposes allowing table feed rates of up to 480 m/min. Modeling and experimental verifications are carried out under dry grinding conditions. Separating active and non-active grains during grinding can be controlled by depth of cut. Four basic grain types, such as cuboids, triangle prisms, triangular pyramid variants and dodecahedrons, are used for grain generation. New cutting edges can be generated by slicing the grain edges and corners by variable fracture plane rotation and distance variation to the origin. Consequently, more than one million grain shapes are possible for the cuboid. Grinding grains are placed on the grinding wheel referential plane. The orthogonal cross-sectional cutting line of each grain is extracted and brought into contact with the workpiece. A triangular distribution for grain protrusion is employed. Good agreement between experiment and simulation in terms of surface roughness, material removal and grain pull-out is reached. Number of grain pull out is calculated and validated experimentally.
