Machining of Austenitic Stainless Steels - the Influence of Various Factors on the Machining Result

Abstract

In today's world, AISI stainless steel accounts for almost half of the world's production and consumption for industrial purposes. Stainless steel is the most popular alloy widely used in the production of parts due to its properties such as high strength, high corrosion resistance or high ductility, but they are hard materials to machine from the metallurgical aspect, such as low thermal conductivity, chip formation, cutting tool wear. The focus of the paper is on machining stainless steel - a review, where various machining problems are discussed by different researchers and their probable solution can provide help to reduce tool wear, increase corrosion resistance, high surface quality finish by reducing machining complexity. The article also provides a detailed specification of the most important factors that significantly affect the lifespan of tools used for machining austenitic stainless steel.
