Microrolling is an advanced manufacturing process for the mass production of miniaturized components. At the micrometer scale, small deviation in material thickness or roll misalignment may significantly alter pressure distribution across the product, resulting in variations in the imprinted texture dimension. An embedded sensing method has been developed to monitor the pressure distribution across the workpiece. A key component of the sensing method is a pressure retrieving algorithm that determines deformation across the roll structure from a limited number of sensing points and converts the data subsequently into pressure distribution, based on the theories of interpolation and back-projection. In this paper, a combination of interpolation (Bezier Curve, Thin Plate Spline, and Kriging) and Tikhonov regularization have been used to resolve the inverse problem.
