Abstract

The surface roughness quality of machining product plays important role when it contacted with other machine components. That quality depends on several parameters setting, such as material, cutting tool, cutting condition and operator skill. The aim of this study is to obtain the optimum setting of turning parameters by using Taguchi method. Three control factors: cutting speed, depth of cut, and feeding at three different levels are selected. A series CNC turning process on AISI 1045 material were performed using L9 (3)3 orthogonal array with cutting fluid. Insert carbide cutting tool is used in the experiment. In order to reveal the optimum machining parameter, smaller the better is quality characteristic selected for surface roughness examination of workpiece. Analysis of experiment results revealed that higher cutting speed, low feed, low depth of cut respectively, provides fine surface quality of machined workpiece. Moreover, feed f parameter was found most influence to the surface rougness quality with 53.73% contribution, cutting speed v provides 23.28% contribution, and depth of cut a provides 17.87% contribution. Confirmation experiment shows that level 3 of cutting speed, level 2 of cutting depth, and level 1 of feed deliver smoothest machined surface of Ra 0,46 µm.

Abstract

The corn harvesting tractor is one of the innovations in agricultural technology. However, there is a problem where the harvesting blade is broken and wears out quickly. One of the factors causing the problem is the angle of inclination of the blade. The smaller the angle of inclination of the blade, the sharper it is but the risk of being easily broken and worn out. For this reason, it is necessary to test the value of the blade slope which has a good strength value. Before this knife is made directly, it is necessary to design and simulate the strength of the blade with a variety of angles. Experimental testing requires expensive costs and a lot of time. The simulation carried out is a static simulation with the finite element method in the solidwork application with AISI 1045 material and 87.05 N force load. The blade with an angle of 310 is the best angle with the maximum value of stress at the connection of the shaft and knife with a value of 20.664 MPa and the displacement results are at a maximum value of 0.018 mm.
