Abstract:
1. A method comprising: defining a pitch spacing for microreplicated features of a microreplicated structure to be created by a microreplication tool that comprises a cylindrical roll; creating a cutting tool assembly to cut grooves in the microreplication tool by positioning first and second tool shanks in a mounting structure such that a cutting location of a first diamond tip associated with the first tool shank is a defined distance from a cutting location of a second diamond tip associated with the second tool shank, the defined distance corresponding to an integer number of the pitch spacing, wherein the defined distance is accurate to within a tolerance of less than approximately 10 microns; creating the microreplication tool using the cutting tool assembly by cutting the grooves; and creating microreplicated structures using the microreplication tool, wherein the microreplicated structures define the microreplicated features at the pitch spacing.
