Abstract

With surface roughness being one of the main quality requirements of machining, it is important to know how different machining parameters influence it. This paper presents experimental results of measured surface roughness values at different parameter combinations in external turning of AISI 1045 steel. Parameters that were used (cutting speed, depth of cut and feed rate) were varied in their selected ranges at three levels. Measurements were performed on the MahrSurf-XR1 surface roughness measuring machine, with the precision of 0.001μm. It was concluded that feed rate has the largest influence on surface roughness, followed by depth of cut and cutting speed. With an increase in feed rate, surface roughness increases, and with an increase in cutting speed and depth of cut, surface roughness decreases.
