What is coller forming.what is material for sheet metal working what is poer required for mechanical press what is hydrolic press what is differe between power work and energy.WHAT IS FEED?

Answer 1

I am not sure what you mean by coller forming- maybe Collar Forming where a collar-shaped circular or oval die is used. a Collet is something else used with a lathe.The questions about the Power required for a mechanical press and a hydraulic press ar too vague to give tacit answers. Hydraulic presses are industrial workhorses rarely seen by the general public, just yesterday there was a swell article in the New York Times about how the Pressure Vessel-of Titanium no less is being fabricated for a new under-development miniature submarine to replace the Alvin. the sub is designed for a service depth of 2l.l20 feet or four statute miles. the pressure on the hull at this depth is in excess of 5.5 Tons per square inch . This is also (the depth ceiling, rated at 3520 Fathoms. a fathom is six feet. what has this to do with Hydraulic presses? well a Hydraulic press, #l54 by name is being used to fabricate the tTitanium pressure vessel- or Barysphere, for the new submarine. this is heavy stuff.Feed is the rate of progression of a tool into the work- say in inches per hour or some similar unit. try some Audel"s machinist library stuff. they are informative and neither dumbed down not overly technical, and get yourself a good calculator if this srstuff is up your alley. the hydraulic press described is 50 feet tall, not the backyard workshop sort of thing. Good luck and hunting. I am not sure of that pressure on the hull figure... all else is verified. consult NY times science time article. for 8.26.
