摘要	Grain size has a significant influence on material properties and in turn influences a machining process. However, the grain size effect on surface integrity of a machined workpiece, such as residual stresses and metallurgical transformation, has rarely been studied. This study focuses on the effect of grain size on subsurface characterization of pure iron subjected to orthogonal cutting. It applies the 3D finite element (FE) modeling method to analyzing subsurface characterization of a machined part made of pure iron. Residual stress and cutting temperature induced in machining of the pure iron parts with different grain sizes are predicted by FE simulation. Recrystallization, dislocation density, and micro-hardness of the machined surface are investigated using the EBSD analysis. The results show that the absolute value of the compressive residual stress decreases with grain size. The finely grained material causes a higher flow stress and cutting temperature, resulting in a larger depth of recrystallization and cutting-induced plastic deformation in the subsurface. Multiple slip bands in the coarsely grained material hinder the dislocation motion during cutting, leading to a smaller plastic flow area.
