BLANK!   It is the age old problem.  Well maybe not for everyone.  But certainly for machinists.  Typically,  a machine shop does not know about the availability of a "blank" and will wind up buying a more expensive piece of bar stock instead. 

So, here is the scenario....Machine Shop X gets a print from their customer to make a short run of a part that is made from Sintered Bronze. Usually Machine Shop X will just go out and buy a piece of Sintered Bronze bar stock to make the part.  This is fine, except now you will spend a great deal of money for the part and a whole lot of time in machining.   BLANK!  Here is where the novel idea comes in!  A "blank" already has an ID and an OD and is found in a number of "standard" sizes.  So you choose which blank size is closest to your finished dimensions and then machine. You can add a flange, increase your ID, turn down your OD, groove holes and much more.  You'll still have to do some machining but it will definitely be a lot less work then the bar stock and Machine Shop X will have saved $$.  Cha-Ching!
Til next time..
