a lathe is a machine tool used to create ___________ parts by rotating the part and moving a stationary ______ point cutting tool past it to remove material in the form of chips.
cylindrical, single
are the CROSS and COMPOUND slide measurements calibrated to the part's diameter or radius?
diameter
what is the definition of facing?
during facing, the tool cuts across the end of a part, moving on the X axis reducing the length of the part
what is the definition of turning?
during turning, the diameter of the work is reduced to a specific size a certain distance back, creating a cylinder

hand cranks
