Abstract

Performance of conventional lathe machine almost depends on how fast the machine cut the workpiece, it means more faster the turning process the material, more finish product are produce in a period of time. The productivity of the machine also high. High productivity needed high rate of metal removal, so it will reduce the cost of manufacturing and operation time. Although the faster process is needed, it did not guarantee the quality of produce the product in term of surface roughness. This project investigates the relation of the machining parameters on ASSAB DF-3 tool steel material that can affect the surface roughness of material and tool wear of cutting tool. Three parameter were selected for speed of spindle, constant depth of cut and feed rate. This project is to investigate the effect of machining parameters such as depth of cut, cutting speed and feed rate on the surface roughness. Then to identify the effect of tool wear in turning operation and optimization model based on statistical method on the machining parameters using the ASSAB DF-3 steel material. The results were discussed in terms of wear behavior of cutting tools and surface quality of the workpiece, which is indicated by surface roughness. A full factorial experimental design was employed in the present work and the results were evaluated using main effects plots. Furthermore, the analysis of variance (ANOVA) method was applied to specify both reactive and non-reactive effects of experimental parameter reactions. The results showed that surface roughness is reduced using low feed rates and high spindle speed in the operations. Furthermore, it was also found that surface roughness increases as the wear rate of inserts increases.
