Contribution to a new method for deep drawing with kinetic control

Autor: Paunoiu Viorel, Teodor Virgil, Baroiu Nicusor, Morosanu Georgiana-Alexandra, Epureanu Alexandru

Publikováno v: MATEC Web of Conferences, Vol 368, p 01022 (2022)

The paper presents a new deep drawing sheet metal method in which, due to the complex geometric shape of the part, there are significant variations in the level of deformation in different areas of the piece. The method aims to im-prove the quality i

Method for Deep Drawing Process Control Using Segmented-Multiple Active Drawbeads

Autor: Maier Catalina, Paunoiu Viorel, Marinescu Vasile, Epureanu Alexandru

Publikováno v: MATEC Web of Conferences, Vol 80, p 14004 (2016)

This paper presents a new method for deep drawing process control. The new method consists in: i) using of a segmented-multiple moving drawbeads; ii) imposing an optimal reference trajectory for drawbeads position; iii) in-process control where contr
