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 cuting 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 diffcult-to-cut metalic 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 dificult-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. Finaly，this paper explored the prediction accuracy of current models and the general applicability of conditioning strategies，offering an outlook on future research priorities.
