| dc.description.abstract | This thesis is quantitative research entitled regarding efforts to find the composition of liquids produced with oil-based ingredients vegetable products to support the production process of biodegradable (Green Machining) machining, reduce production costs, non-toxic. Cutting fluid based on palm kernel oil with the addition of MoS₂+Graphen nanoparticles is expected to affect the productivity of the machining process parameters. So that the characteristics of the fluid developed using PVD and CVD coated chisels are obtained.
Data were collected through research data collection techniques through library research through journals and then analyzed using qualitative and quantitative descriptive analysis. Next, design a data retrieval experiment using the Taguchi method.
In the tool potential test, the independent variable values were obtained, namely (v=115 m/min, f=0.2 mm/rev, and a= 1 mm) at the cutting length (CL)= 100-300 mm. At the maximum cutting distance, the liquid has the potential to be superior, namely CF4 and CF5 on the PVD tool, then CF2 and CF3 on the CVD tool. In this test, the role of the MoS₂ nanoparticle additive in the developed CF4 and CF5 contributes to reducing the coefficient of friction so that the lowest tool wear (Vb) is 28 microns. The feeding speed of 0.1 m/rev produces the lowest Vb value, 48 microns. The characteristics of the developed cutting fluid contributed to the hard machining experimental tests and were able to compete with commercial fluids, in this case, Fuchs.
In line with the conclusions above, it is recommended to use more sophisticated and adequate equipment to obtain the purpose of the developed fluid characteristics. | en_US |
