Abstract

In the manufacturing industry the use of cutting fluids is well known. However, cutting fluids have several side effects such as polluting the environment, and in some cases there are people who have allergies to these conventional cutting fluids. The purpose of this paper is to determine the effect of biolubricant as cooling fluid on the wear on vertical milling tool wear. In this study the material used is mild steel and Endmill made from HSS with a diameter of 6 mm. Biolubricant is made using the process of making biolubricant uses a transesterification process with ingredients; wasteused cooking oil, ethanol (98%), and potassium hydroxide. In the process of taking data using a milling machine, the variations used are; without using cutting fluid, using conventional cutting fluid, and using biolubricant. With speeds of 500 Rpm and 930 Rpm. In the Chromatography-Mass Spectrometry (GC-MS) test, the results obtained the number of esters as much as 57.12%. In the new tool, the tool area is found as follows: point (1.) 0.012 cm2, point (2.) 0.013 cm2, point (3.) 0.022 cm2, and point (4.) 0.22 cm2. The tool angle is 68.957° and the tool weight is 12.31 g. In the milling process using conventional cutting fluid, the areas obtained were: point (1.) 0.008 cm2, point (2.) 0.007 cm2, point (3.) 0.012 cm2, and point (4.) 0.16 cm2. The tool angle is 88.005° and the tool weight is 12.16 g. In the milling process without using coolant, the areas obtained were: point (1.) 0.016 cm2, point (2.) 0.017 cm2, point (3.) 0.023 cm2, and point (4.) 0.24 cm2. The tool angle is 96.670° and the tool weight is 12.07 g. In the milling process using biolubrication, the areas obtained were: point (1.) 0.012 cm2, point (2.) 0.013 cm2, point (3.) 0.019 cm2, and point (4.) 0.19 cm2. The tool angle is 72.448° and the tool weight is 12.2 g. It can be concluded that the milling process using biolubricant with the provision of biolubricant in the milling process is less than using conventional cutting fluid, getting more satisfactory results compared to the cutting process without cutting fluid and using conventional cutting fluid and without cutting fluid, this can be seen from the data obtained.
