摘要

The machining removal of aerospace alloys constitutes a highly intricate interfacial tribological system. The severe frictional interactions at the tool-workpiece and tool-chip contact interfaces generate complex thermomechanical loading, which significantly accelerates tool wear and consequently elevates manufacturing costs. In this context, micro-textured cutting tools have emerged as a prominent research focus within the academic community, owing to their potential for interfacial friction mitigation. However, there is a lack of systematic reviews on micro-textured tool technology for aerospace alloys, hindering the provision of accurate guidance and selection criteria for its industrial application. To address the above challenges and demands, this review first introduces the action mechanism of micro-textured tools and discusses common processes for the design of micro-textured tools. Secondly, it systematically compares current preparation processes for micro-textured cutting tools, and highlights the mechanism, equipment and advantages of composite preparation processes in addition to single preparation routes. Thirdly, it summarizes the current application status of micro-textured tools in the cutting of aerospace alloys. On this basis, this review conducts a specific cutting energy assessment on the available data via the classical specific cutting energy calculation formula, demonstrating the effectiveness of micro-textured tools in reducing energy consumption. Finally, it discusses the key challenges and future prospects for micro-textured tool technology. It aims to provide theoretical guidance and technical support for the clean and precision manufacturing technology of aerospace alloys under the trend of cutting fluid reduction.
