CUTTING TOOL ASSEMBLY INCLUDING DIAMOND CUTTING TIPS AT HALF-PITCH SPACING FOR LAND FEATURE CREATION

摘要

The invention is directed to a cutting tool assembly that include multiple diamonds to define multiple cutting tips. A first diamond is positioned in the cutting tool assembly to create a first groove in a microreplication tool and a second diamond is positioned in the cutting tool assembly to create a second groove the microreplication tool, wherein the first and second grooves define integer pitch spacing of a microreplication structure to be created using the microreplication tool. In addition, a third diamond is positioned in the cutting tool assembly between the first and second diamonds to create a land feature in the microreplication tool between the first and second grooves. The invention can improve land feature creation by using a third diamond tip, rather than leaving the land features untooled and defined by the original untooled surface of micro-replication tool.
