Selection of the Milling Conditions for Hardened Steel

Abstract

In a milling process, it is difficult to optimize precision, tool life and processing efficiency together in one study. It was necessary befbre this study to adjust the process conditions every time based on the objective of processing a certain product. In this study, the two-stage design method was used by conducting two separate experiments. In the first stage, transformability was used for optimization by conducting an off-line experiment. In the second stage, a simple life test was conducted. The tool life and processing efficiency were converted monetarily using the Loss Function. After the optimization, it became possible to select the best cutting speed based on the objective of processing, and determine the relationship between tool life and processing efficiency.
