If your project requires use of the Precision Machining Laboratory you must fill out a, MACHINING WORK PERMIT!
PML
The Precision Machining Laboratory (Towne 169) houses equipment to aid various machining methods. It contains three manual mills, five manual lathes, four Prototrak hybrid mills, three CNC mills (Fadal VMC-15X, Haas MiniMill, Haas OfficeMill), one CNC lathe (Haas TL-1), and various other metal prototyping equipment. To use the machine shop, you must obtain access and follow all safety rules and policies.
