Flange Wrinkling in Deep-Drawing: Experiments, Simulations and a Reduced-Order Model
Journal of Manufacturing and Materials Processing, 2022 Flange wrinkling is often seen in deep-drawing process when the applied blankholding force is too small. This paper investigates the plastic wrinkling of flange under a constant blankholding force.

Deep Vectorization of Technical Drawings [PDF]
, 2020 We present a new method for vectorization of technical line drawings, such as floor plans, architectural drawings, and 2D CAD images. Our method includes (1) a deep learning-based cleaning stage to eliminate the background and imperfections in the image and fill in missing parts, (2) a transformer-based network to estimate vector primitives, and (3 ...

Pressure Lubricated Deep Drawing
Bulletin of JSME, 1961 In this paper, a method promoting a fluid lubrication in the deep drawing of sheet metals is introduced. Possibilities of this method are proved by laboratory scale experiments on aluminium and reported. It is shown that the process brought about many encouraging results for the improvement of the drawing ratio.

A Study of the Lubrication Mechanisms in Deep Drawing
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1980 The oil film thicknesses between the tools and the workpiece and their changes during a cup drawing operation are analytically predicted to facilitate estimating the effects of the process variables on the lubricating conditions, including the blank holding speed, the time elapsed after setting the blank holder until the beginning of the punch ...
