Influence of Process Parameters on the Surface Roughness during turning operation of High Strength Steel

Abstract

High strength steels are used in many high-end applications. Due to the high cost of raw material, manufacturing engineers should be very careful during their machining process. Surface finish is the critical factor in the turning process of combustion chambers of gun barrels. It should conform to the required accuracy values. This paper analyzes the impact and parameters of the process have on the roughness of the surface. The impact is analyzed during turning operations of high strength steel material. The parameters considered include feed rate, depth of cut and cutting speed. The test plan was implemented through 125 test specimens. The latters were divided into 25 groups. Each five groups were subjected to one common machining speed. Each group was machined using five levels of cutting depth. Each depth was processed using feed rate having five levels. Tessa was used for the examination of the roughness of surface. The experimental findings were compared to the requirement of the surface finish on the basis of the design drawing of gun barrel. The combination of the process variables showed excellent agreement with the design drawing of gun barrels.

Minimization of turning time for high-strength steel with a given surface roughness using the Edgeworth–Pareto optimization method

“…In anticipation of the next sixth technology revolution, it is becoming an increasingly important technique for processing large data sets using artificial intelligence and the integration of artificial intelligence algorithms in automated production. Many previous investigations have been devoted towards developing prediction models for rough turning [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Risbood et al [1] researched and produced models for forecasting roughness and dimensional deviation for dry and wet turning of mild steel rods.…”

“…Tootooni et al [18] reported surface roughness using a noncontact measurement method during the turning process. Abbas [19] analyzed the effect of the feed rate, depth of cut and cutting speed on the surface roughness in turning high-strength steel. Though all the previously mentioned research [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] provided prediction models of surface roughness, they failed to solve the problem of determining the optimal cutting parameters for the minimum surface roughness and maximum production rate.…”
