Need some more information. What kind of metal? 1/2 inch thick, but what, an inch wide, or twenty feet? And is there some kind of lever or gearing system on the blade mechanism? If so this will reduce the load on your hydraulics. What power will the diesel engine pump out? This will help determine the hydraulic needs. You got any drawings or anything? More information would definitely help you out here!

Thanks for your reply.  The metal is 1/2 thick....we will tourch cut it into 12' lengths. I will get the specs on the diesel ... it is on the way in today...bought it at an auction. Gearing is a good idea....this should help control the load on the blade too???? I will be back with more.

Thanks

Gearing will not reduce the load on the blade, - to cut the metal you still have to apply the same amount of force to the metal (and blade!) whether or not you are using some kind of gearing mechanism. When you say you are 'implementing' this machine, do you mean you already have one which just needs a power pack, or are you actually designing one? In the first case it should just  be a case of working out what the machine is actually capable of, and fitting a power system to it. If you're actually designing it, there will be a lot more considerations!

Let me try again. There is a quillotine sheer in parts. Meaning I have to assemble. My boss is bidding on a diesel engine...which I do not have the specs yet. He also has hydraulic cylinders which he wants to use.

Here is the delima. I do not have any of the information yet. He is traveling and moving all of this to our new location this week.  I am trying to get a jump on the implementation.

This is what I really need to know. We are cutting 1/2" max sheet metal. The widths will not exceed 12'. The sheet metal will be fed into the guillotine length wise...cut to various dimensions. What force will it take to cut this meaning the rate on the cylinder and the horse power required? A formula would work.

Thanks Again

Check out the followong page: /sheet_metal_pierce.htm ,

Once you  detemine the force required to shear the metal, then you will have to calculate the mechanism force applied etc...
