DETERMINATION OF THE EFFORTS THAT OCCUR IN THE CASE OF PERFORMING INNER THREADS WITH FORMING ROLLERS
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The aim of this paper is to present a simplified model for the theoretical calculation of the deformation efforts that occur in the case of performing inner threads by forming rollers. Firstly, determination of the normal stress distribution along the roll-blank separation line is presented and then the calculus of the resulting force of deformation.
