Machinability is how easily material can be machined by various cutting operations. Typically, the harder a material is, the lower its machinability. Additives and cold working may improve a material’s machinability. The better the machinability, the longer your cutting tools will last.

Speed is how quickly the edge of the cutting tool goes through the surface of the workpiece. It typically describes movement on a rotational basis. Feed is the rate at which the whole cutting tool moves through the whole cut. It’s typically a motion on a linear basis. Depth of cut is the thickness of material that is removed with one cut from the tool. It has little effect on a tool‘s life.
