1. A micro-milling system for modifying an extrusion die comprising a plurality of die pins, comprising:
a micro-milling machine comprising a micro-cutting tool coupled to a spindle of the micro-milling machine, the micro-milling machine further comprising a workpiece holding device configured to secure the extrusion die proximate the micro-cutting tool:
an integrated vision system configured to capture location data of the plurality of die pins, the location data comprising at least one of angle, orientation, or length of each side surface of each die pin of the plurality of die pins; and
a controller configured to generate a die pin location map using the location data, generate a numerical control file using the die pin location map, and control the micro-milling machine to guide the micro-cutting tool along a tool path generated from the numerical control file to machine the plurality of die pins one die pin at a time individually and independently of machining another die pin of the plurality of die pins.
