Reverse grooving for cross-screw reduction of tube bullets

Abstract

The technology of cross-screw reduction of tube billets with reverse correction is presented. The calculation of the change in the geometry of the workpiece with a change in the feed angle is carried out. It is shown that for small feeding angles the change in geometry is insignificant, which makes it possible to conduct reverse correction of the workpiece. The calculation of parameters of reverse grooving is carried out.
