Hard turning is a machining process which is used to machine the materials which have Hardness rating of 45 HRC and above. The process is capable of giving the surface finish of a very precise grinding operation but at a much lower coast. In similar way the hard milling operation is there. Both these machining techniques have become very popular these days as a wide range of materials for tools are available. Various experimental studies been conducted by the researchers on the topics like tool wear and tool life, microstructure change, white layer formation, surface integrity and fatigue strength of hard milled surfaces. This review paper compiles the results and conclusion of above experimental studies.
