Finite element analyses of female-thread forming process and loosening proof of self-tapping screw

open access: yesNihon Kikai Gakkai ronbunshu, 2023
Tapping screw fabricates the female thread due to plastic deformation during screw rotation. Since the tapping screw skips the preliminary fabrication of female thread, it is widely used for the tightening in the fields of such as electric parts and car ...

Forces and Plastic Work in Cutting

open access: yesCIRP Annals, 1983
Prolific considerations in C.I.R.P. give rise to a further step in the development of a plastic cutting model. Basically two different primary shear zone geometries are assumed: with one and with two shear planes respectively. For both geometries two energetically different approaches are developed.
