Abstract:

Machined surface integrity, a composite reflection of the geometric, physical, chemical, and mechanical properties of the machined surface layers, is dictated by the thermo-mechanics loads and material removal modes inherent to the cutting processes. This integrity directly governed the in-service performance and lifespan of engineered components. A thorough investigation into how conditioning strategies influenced surface integrity was therefore fundamental to realize high-integrity surfaces, and was critically important for optimizing the machining of difficult-to-cut metallic materials. This review began by categorizing the metrics of machined surface integrity for these materials based on three aspects: geometric features, microstructural evolution, and surface-layer mechanical properties, while also summarizing the approaches for developing predictive models. Subsequently, it elucidated research advancements in machined surface integrity conditioning strategies of difficult-to-cut metallic materials, critically comparing the distinct influence mechanisms of tool and process optimization, multi-energy field assisted machining, and workpiece pre-treatment on machined surface integrity. Finally, this paper explored the prediction accuracy of current models and the general applicability of conditioning strategies, offering an outlook on future research priorities.

Key words: difficult-to-cut metal, classification of machined surface integrity, surface integrity prediction model, surface integrity control strategy
