The document discusses the 2013 technical conference for PMPA and provides details on CNC multi-function printing for machining an aluminum part including tolerances, materials, machining processes, tooling, and cycle times. Key steps include rough and finish turning, drilling, milling flats and slots, cutting radii and corners, and deburring. The part will be machined from 2011-T3 aluminum alloy using multiple spindles and tools with a target cycle time of 3 minutes 24 seconds and a production rate of around 17 pieces per hour.
