Abstract

In small scale industries, Single-point HSS cutting tools are frequently used in machining operations to comply in lathes. The machines work monotonously for a long time; soon, the deformation of the tool occurs. The continuous contact between the static tool and the rotating job creates heat due to frictional rubbing between them. Therefore, the tool wear increases, which corollary in the inferior surface finish of the job. The bigger the rake point, the lower are the cutting powers and power better is the surface completion. The angle chosen is, therefore, a Comprises efficient cutting and tool strength. To avoid such problems, the tool's hardness is necessary to increase. The main objective is to measure the hardness, flank wear, surface roughness, and microstructural changes for both cryogenic treated and untreated single point cutting HSS tools.
