supposedly a native name for the swastika (used as a decorative device), but only attested in a single, damaged c. 1500 manuscript, and in that it might rather refer to any sort of device used to fill the bottom (foot) of a design. "[I]t is even possible that it may have been a mere nonce-word" [OED].

Meaning "to apply machinery to, to make or form on or by the aid of a machine" is from 1878. Related: Machined; machining.
