Low setup cost for small Quantities.Machining has two applications in manufacturing.For casting,forging,and press working,each specific shape to be produced,even one part,nearly always has a high tooling cost.The shapes that may he produced by welding depend to a large degree on the shapes of raw material that are available.By making use of generally high cost equipment but without special tooling,it is possible,by machining; to start with nearly any form of raw material,so tong as the exterior dimensions are great enough,and produce any desired shape from any material.Therefore .machining is usually the preferred method for producing one or a few parts,even when the design of the part would logically lead to casting,forging or press working if a high quantity were to be produced.
Close accuracies,good finishes.The second application for machining is based
