In the field of manufacturing High-speed steel plays a major role for cutting, drilling and some other major operations when compared to high carbon steel. Currently only pure HSS is used without any coating on it, in this paper we have coated the HSS with chemical element like chromium, zinc and nickel for end mill cutter. This cutter was used to machine AISI 4340 steel at axial and radial engagement. The machining operations were carried out with proper production conditions and periodically interrupted the wear condition of the cutting tool. Cutting conditions wear carefully chosen, so that a linear wear model for the useful life of the cutting tool could be statistically tested. One phase of a testing used non-coated tools from different suppliers and the non-stationary linear wear models provided a stochastic representation to determine tool quality using reliability and economic measures. Another phase used the coated tools and a stationary linear wear model to relate force, power, specific cutting energy, and mechanistic model parameters to service life measures. This paper also discussed the tool wear and life factor after coating compared with conventional cutting tool (HSS).
