ANALYSIS ON THE SPINNING FORCES
IN FLEXIBLE SPINNING OF CONES
Abstract:
Flexible spinning is a new type of spinning process where spin-forming is performed without using a mandrel. Combining shearing and rolling processes, the calculation formulas of the spinning forces in flexible spinning of cones is presented. The effects of the main processing parameters, such as gripping force G applied to the blank by the inner roller, the feed rate of rollers f and the roundness radius of outer roller ro, on the spinning forces are analyzed experimentally and theoretically.
