i am not an expert in the field, i just wanted to help. check the literature through scopus and see what has been mentioned previously, based on the region and the industry it could be different

This geometries depend of the part, dimensions and materials. You can check in the litterature (Handbook for exemple) differents types of the flash geometries. To define exactly the geometrie for your application, I can help you but today all my documents are in french ...You can send me an example of your par, if you want.

For me reading french is not a problem. Mi idea is to investigate the influence of differents shape of flash over force and energy value resultant in fixed geometry piece.

Mercie beacoup Monsieur.

Hi Martinez

When you want define flash (type, geometry, radius) you use the minimal pressure that it is necessary to obtain the good geometry of the part not only with initial dies but with used dies. So you obtain the thickness and width.of the flash. So, this is the optimal flash, because if you increase the thickness of the flash, you don't have the internal pressure to obtain the final part and if you decrease thickness of this flash you increase the internal pressure uselessly. With this fact, you increase load and energy of your press and mainly the wear of the dies.

In fact, I have some tables to define flash in function of part morphologies and matrials and, if necessary, I use FEM optimisation.

We can exchange about example if you want

Hi Regis. My idea is take one geometry piece and try out differents flash shape that the bibliografy recomend. Finally try out the best geometry than minimize the load and energy. All the try outs makes with numerical simulation. We want to make this activity to show the results to the forging sector from argentina which dont use this tools. I need the differents tables please.
