Abstract：
|
|
Ring rolling has been widly applied at home and abroad. Research for technique and deformation has been made much progress, but,feed rule has been made only a few .Usully,control is finished according to experiential curve or condition of uniform expansion of the ring. Several practicable feed velocity (maximum,minimum)curve has been put forward in this paper by theroetical research,may be used for basis of controlling of reed of ring rolling.
