Effects of deep cryo treatment of high speed steel on the turning process of a medium carbon steel

This paper describes the effects of deep cryo treated high speed steel. In recent research, the cryo treatment has been acknowledged by improving the life or quality performance of tool materials. The molybdenum based high speed tool steel is frequently used in industry till date. Therefore, it is essential to observe the tool performance in machining of medium carbon steel (AISI 1045) on dry turning operation. The effect of untreated and deep cryo treated tool in turning of medium carbon steel is analyzed using Taguchi approach. The results indicated that the main cutting force obtained from cryo treated tool significantly decreased to 29 % when compared with the untreated tool. Also, it revealed that the surface roughness of machined component using deep cryo treated tool was better than of the untreated tool.
