A comparative study of the cutting parameter in milling process under different material

Abstract

In the present study, the incidence of the variation in feed rate per tooth and depth of cut for SAE 4340 alloy steel and SAE J431 steel castings was analysed and in which material this variation is most noticeable. For this purpose, the machining process studied was milling. This is a machining operation in which a workpiece is passed in front of a rotating cylindrical tool with multiple cutting edges. For this study, the feed rate per tooth and depth of cut were varied by 4 values each. The feed rate ranged from 0.002 mm to 0.008 mm and the depth of 2 mm to 8 mm found that for both parameter variations cutting speeds always decrease with increasing both feed per tooth and depth of cut and that feed per tooth and depth of cut significantly affect process costs.
