Investigation of surface roughness and tool wear in milling of AISI 4340 steel

Abstract

Abstract Investigation of surface roughness and tool wear in milling of AISI 4340 steel has been conducted with a 4-flutes endmill. The relationships between cutting force, surface roughness and cutting parameter were investigated To determine the tool life of the tool. It is required to research the wear of the tool and the roughness of the machining results on the material tested. In this research, the test material used is AISI 4340 steel with a cooling method in the cutting process. The cutting model is slot mill cutting. To determine the wear of the cutting, a variation of the cutting thickness was performed where the selected cutting thickness was 0.5mm, 1mm, and 1.75mm. The tests that have been done are surface roughness testing, tool wear, and tool photos after cutting. The result obtained from the study is the highest level of roughness on the material cutting poses with a cutting thickness of 1.75 mm. In addition, the most optimal wear results on cutting with a cutting depth of 1 mm.
