Date :Définition
A machine tool working with a milling cutter which has been formed to the shape of the space to be cut; the tooth spaces are machined one at a time; the cutter is gradually fed across the face of the spur-gear blank which is held stationary; at the completion of the cut, the cutter is rapidly returned to its initial position, the blank is automatically indexed a suitable amount, and another tooth space is cut; a spur-gear blank is stationary while a milling cutter is in contact with it; a helical gear blank is given a slight twisting motion when being milled; on plain or universal milling machines the process is similar except that the work feeds and the indexing is not automatic.
