Chip Temperature in Dry Rough Milling of Magnesium Alloys Using Different Rake-Angle Tools

Year: 2026

Type: article

Abstract: This study examines how variations in cutting parameters and end mill rake-angle affect chip-temperature in the cutting zone. This study describes a method involving end mills with varying rake angles to measure the temperature of chips in the cutting zone during the dry rough milling of magnesium alloys. The chip temperature is determined by infrared spectroscopy. The influence of milling parameters (i.e., cutting speed, feed per tooth, and depth-of-cut) on the maximum chip temperature was analyzed. Box plots, bar charts, and 2D graphs are used to display the chip temperatures. We address issues that come up while recording a signal with an average emissivity coefficient value and how to resolve them. The tests yielded chip temperatures that were not higher than 366 °C. Thus, for a variety of machining parameters, the dry roughing milling procedure using carbide tools with different rake angles can be deemed safe. The proposed approach to detecting the chip temperature and processing findings constitutes a novel and efficient way for evaluating safety in the dry milling of magnesium alloys.
