A method to reduce the microstructure closing error of roller mold ultra-precision machine tool machining

Abstract

The invention discloses a method for reducing closure errors of machined microstructures of an ultra-precise machine tool of a roller mold. The method includes the following steps of 1, analyzing theinfluence caused by a temperature change in a machining process of the ultra-precise machine tool, and optimizing a machining process to reduce closure pitch errors of the microstructures when a sizechange caused by the temperature change to a roller is within a nanometer scale and the required closure pitch errors of the microstructures of the roller mold are very small; 2, according to the diameter of the machined roller mold, the number of the microstructures and a temperature change range, selecting the number of areas which need to be partitioned by means of a multi-partition method; 3,according to partition frequency selected in step 2, calculating the angle position of each microstructure when there are remainders or not, writing down general term formulas and processing the remainders; 4, according to spatial angle distribution, obtained in step 3 through calculation, of the microstructures, writing a machining program to achieve machining by means of the multi-partition method. The method has a significant meaning on improvement of machining quality of the microstructural roller mold, manufacturing of ultra-large optical transfer print membranes and the like.

Description

technical field [0001] The invention relates to a method for reducing the microstructure array error of a roller mold processed by an ultra-precision machine tool, in particular to a method for reducing the microstructure closing error of a roller mold processed by an ultra-precision machine tool. Background technique [0002] The microstructured surface with certain regular features can make the object have special physical and chemical functions, such as super-hydrophobic properties, stealth properties and drag reduction properties. If the parameters such as shape, distribution and size of the surface microstructure are designed, different functional requirements can be met, so it has a very wide range of applications in aerospace, optoelectronic display, solar concentrated photovoltaic and other fields. Roll-to-Roll replication processing technology has become the mainstream production process for manufacturing large-area and high-quality optical microstructures due to it...

AI Technical Summary

Problems solved by technology

This kind of roller mold with seam error will have a large error every time the roller rolls one circle during the Roll-to-Roll imprinting process, and the microstructure products of its replication molding are obviously periodic The pitch error, but can not achieve its functional requirements
