Abstract

MÉTODO PARA GERAR MICROESTRUTURA EM UM FILME POR UM ROLO. A presente revelação refere-se a um método para projetar um módulo de molde de microestrutura esférico (604-614) para ser incorporado em um rolo de calandragem (600) para gerar uma microestrutura (108) em uma superfície plana (104), compreendendo calcular uma primeira curvatura (204) em uma superfície plana de seção transversal (202) para um primeiro ponto de microestrutura da módulo de molde de microestrutura esférico, calcular uma segunda curvatura (210) de uma superfície esférica (102) do módulo de molde de microestrutura esférico, medir um raio (214) da superfície esférica (102), sendo o raio (214) do centro da superfície esférica (102) até o primeiro ponto de microestrutura e determinar uma localização da microestrutura (108) na superfície plana (104), sendo a localização derivada da primeira curvatura (204), da segunda curvatura (210) e do raio (214).
