Optimizing Dual-Microstructure Parameters in Ball-End Milling Tools: Synergistic Effects and Parameter Combination Analysis
Source abstract
Abstract
To address the issues of high cutting speeds and low surface precision during milling, this study investigates the effects of front and back cutting face microstructures on ball-end milling cutters processing 304 stainless steel. Firstly, a theoretical energy model for front and back cutting face microstructures is established to verify the feasibility of embedding microstructures. Then, finite element analyses are conducted on cutters with varying microstructure parameters on front and back cutting faces to determine reasonable parameter ranges. Parameter combinations are subsequently used to manufacture front/back microstructured cutters, which undergo FEA validation. Finally, milling experiments are designed with milling forces, tool wear, and workpiece surface roughness as evaluation metrics. The results demonstrate that front/back microstructured cutters reduce milling forces by 19.4%, cutting temperatures by 19%, and workpiece surface roughness (Sa) by 43% compared to non-microstructured cutters, while significantly mitigating tool wear.
