Cutting is the separation or opening of a physical object, into two or more portions, through the application of an acutely directed force.Cutting is a compressive and shearing phenomenon, and occurs only when the total stress generated by the cutting implement exceeds the ultimate strength of the material of the object being cut. The simplest applicable equation is: Cutting has been at the core of manufacturing throughout history. For metals many methods are used and can be grouped by the physical phenomenon used.It is the process of producing a work piece by removing unwanted material from a block of metal,in the form of chips.
