Rolling – extrusion, FEM, drills.


The method of semi – finished drill parts forming by means of rolling – extrusion process is show in this work. Application of Finite Element Method (FEM) allows for
analyzing this process with application of different kinematics parameters. Chosen in numerical calculations cases of rolling – extrusion were verified in laboratory conditions with use of prototype aggregate PO-1. The billets for these tests were made from commercially pure lead. Obtained results confirmed possibility of rolling – extrusion technology application in proposed scope of application.
