This is a description of how CNC milling can be used to machine a variety of parts with minimal human intervention. The methodology uses a layer-based approach(like traditional rapid prototyping) for rapid and semi-automatic machining of commonly manufactured par-geometries from a variety of material. Process parameters such as the number of orientation, tool containment boundaries, and tool geometry are derived from CAD data. In addition. Automated fixturing is accomplished through the use of sacrificial structure added to the CAD geometry. This project begin by describing the machining methodology and then presents a number of critical issues needed to make the process automatic and efficient. Example parts machined using this methodology are then presented and discussed.
