In this study the surface roughness characteristics of structure steel were investigated according to cutting conditions. The surface characteristics of rod surface are usually investigated at various cutting conditions such as cutting speed, feed rate and cutting depth of workpieces. Experiments were conducted in a CNC lathe and the surface roughness of workpiece for dry and wet cutting were estimated. Machining was performed with revolutions per minute of 3200rpm, cutting depth of 0.8mm and 1.0mm, and feed rate of 0.15mm/rev, 0.25mm/rev, cutting oil of both wet and dry respectively. As a method of evaluation, piston rod was measured for each cutting.
