Shank is a tool element. This is fixed on the top plate. Shank is fixed in the press ram. This should be strong enough to take the total weight of the punch until and stripping force. The diameter of the shank fits the bore within the press ram. The shank diameter is standardized in relation with the press ram. The shank diameter is standardized in relation with the press ram bore, which is varying from press to press depending on the capacity of the press.
There are different types of shank standards. Selection of the shank is based on the need base. It is made out of mild steel. The location of the shank point is very important and different load acting on top plate is to be considered. The balancing of cutting punches is one of the most important aspects to be considered during the punching operation. Unbalanced force distribution on the tool top may cause under wear on the punch and die as well as on the pillars. The resultant force of all the cutting forces, acting on many different punches should pass through the shank centre.

Hi - some great work here. I was just wondering if you'd like to have your own mechanical engineering/CAD blog on my site, the Mechanical Design Forum? You might find a better and appreciative audience than here, and would probably receive more feedback. We now have over 6,000 members, lots of traffic, and your latest posts would also get showcased on the main page of our new mobile apps! (Details of mobile apps: http://is.gd/brtAMb)
Here's a link to the blog section, should you wish to start a blog:

Just a thought, but keep up the good work anyhow!
