Precision distribution design of micro-textured ball-end milling tool and the analysis of its effects on the strength of the insert

Abstract

Most prior studies have not carried out a precise theoretical analysis and design of micro textures and have thus only conducted experimental analyses of cutting performance that lack theoretical analysis and reliability. This study thus first determined the specific micro-textured application area from a theoretical point of view, based on the contact relationship between the rake face and the chip. Secondly, the micro-textured distribution laws were determined for this area along with a definition of the distribution boundaries of the micro textures. Thirdly, the influence of cutting depth on the number of micro-textured rows and columns was analyzed, and these optimized numbers were thus obtained. Finally, the influence of the micro-textured distribution on the strength of the insert was simulated and analyzed. The results showed that the application of micro textures had no significant effect on the strength of the tool. The results of the research ensured consistency for subsequent research into the milling performance of micro-textured ball-end milling tools.
