Abstract
The metal fabrication process, especially in the metal drilling process, one of the parameters that affect the quality of metal drilling results is cooling media, because it affects the life of the tool used. This paper aims to determine the performance of using fan chips as an alternative to cooling media in the metal drilling process area. The method used with flow simulation and drilling process experiments on workpiece made from aluminum alloy 5086 in experimental testing uses a variation of the spindle rotation of a metal drilling machine with the aid of taking test data with an anemometer and infrared thermometer in the drilling process of the aluminum alloy 5086 workpiece. After experimenting with chips through spindle rotation variations, cooling of the process area occurs when the engine spindle rotation rotates above 1000 rpm and the temperature decreases at the end of the tool area by 5oC compared to without using fan chips. A decrease in the temperature of the work area of the drilling workpiece aluminum alloy 5086 compared without using fan chips has an impact on increasing the tool life limit by 12% or increasing tool life 5 minutes.
