Abstract
A method of manufacturing an extrusion die (102, 152, 302). The method comprises providing the extrusion die (102, 152, 302), the extrusion die (102, 152, 302) having a plurality of die pins (154, 316) defining a plurality of slots (156, 320), the plurality of die pins (154, 316) having an initial die pin width and an initial die pin depth and the plurality of slots having an initial slot width (Ws) and an initial slot depth (Ds), providing a micro-milling machine (104) with a spindle (122), providing a micro-cutting tool (120) coupled to the spindle (122), mounting the extrusion die (102, 152, 302) proximate the micro-cutting tool (120), and removing material from one or more die pins (154, 316) using the micro-cutting tool (120), the micro-cutting tool (120) making one or more cutting passes against the one or more die pins (154, 316) to remove the material. Micro-milling apparatuses and further methods are provided, as are other aspects.
