Investigating Flank Wear and Cutting Force on Hard Steels by CBN Cutting Tool by Turning
نویسنده
چکیده
In this research work a series of tests were conducted in order to determine flank wear and cutting force FY on hard AISI 440 C martensitic stainless steel and SCM 440 alloy steels. The operating parameters are cutting speed, feed rate and a constant depth of cut to investigate the flank wear and cutting force. No cutting fluid was used during the turning process. The cutting tool used was CBN tool. The flank wear was more on CBN tool and caused by thermal softening at cutting edge. In turning alloy steel, low temperature generated and less flank wear formed. The cutting force measured on stainless steel was low due to chip softening. The less concentration of heat on the chips result more cutting force while turning SCM 440 steel. Saw tooth chips were formed in turning AISI 440 C steel in all cutting parameters and no such chips produced by SCM 440 steel.
