Abstract

Plastic films with embossed micro-structured patterns have been widely used in backlight guide panels. The mass production of these films demands for ultra-precision roller embossing of micro-structured patterns on plastic films by precision pattern rollers. Due to the heavy workload and high precision requirements, ultra-precision rollers with microstructures are very difficult to be machined in the level of submicrometer form accuracy and surface finish in nanometer range. This paper presents theoretical and experimental studies of ultra-precision machining of precision rollers with microstructures. The machining mechanism for precision roller is firstly explained, and hence a study of effect of cutting strategies on surface generation in ultra-precision machining of micro-structured pattern rollers is presented. This includes the study of different cutting trajectories, length-to-diameter ratio of the rollers, mounting method for the rollers, the number of cuts in the formation of the micro-structured patterns, as well as the time budgeting for adopting different cutting trajectories in ultra-precision machining of micro-structured pattern rollers. The results of the study provide an important means for enhancing the surface quality and optimizing the time for machining precision rollers.
