- Abstract
This paper investigates the impact of high-speed machining with heat-assisted machining (HAM) on the machinability of heat-treated SKD61 steel, utilizing alloy cutting tools. The study encompasses microstructure analysis, mechanical properties evaluation, chip color examination, surface roughness assessment and cutting force measurement during the machining process. Experiments are conducted under controlled conditions with advanced equipment. Findings indicate that at 200°C and 350°C, SKD61 steel's microstructure remains unchanged, while at 500°C, there's a superficial alteration of approximately 0.05 mm thickness. Material hardness remains consistent across temperatures. Unique chip color variations serve as temperature indicators. Cutting force consistently decreases with rising temperature, highlighting the intricate relationship between temperature, material behavior and cutting mechanics. Surface roughness improves with higher temperatures, emphasizing the potential benefits of HAM in precision manufacturing.
