Abstract

Nowadays, there are many studies done on the effects of the cutting tool and other parameters to the surface finish of the product. There are also studies done to study the effect of the machining parameters on the cutting tool itself. Those studies were conducted to find the suitable parameters in order to optimize the metalworking process. In metalworking industries, good surface finish is one of the criteria that the product should have. Therefore, the study on chatter stability has carried out widely by studying the effect of end mill used in the metalworking process such as helical ball end end-mill, and straight end-mill on the product being machined. There is some studies that are also study the effect of the straight flute end mill and spiral flute end mill in chatter stability to the product that been machined. Since there is no performance comparison made to both straight and spiral flute end mill, this study focused on performance different for both end-mills at the end of the study. The comparison will be analyzed by referring the trend line showed by the plotted graph after the data produced through the experimental data collected. The result evaluated based on the experimental data in this study shown that the spiral flute end-mill have the best performances compared to straight flute end-mill and end-mill with a helix angle of 15° is more stable than end-mill with a helix angle of 30° in-terms of cutting forces, surface roughness and tool wear performances.
