Evolution of textures on surfaces created using plane strain machining (PSM) under machining-relevant thermomechanical conditions is studied and compared against that in the chips. By analyzing orientation distribution functions, it is shown that the texture on the surface is comprised of prominent and distinct fibers. By analyzing the pole figures of chips and the surface, it is shown that the two textures have features distinct from one other, even though the scale of the microstructure on the surface and the chips are traditionally considered to be comparable. In situ characterization using high speed imaging of PSM is coupled with a visco-plastic self-consistent (VPSC) model and is used to predict the pole figures in the chip and the surface. A finite element model of PSM is generated and coupled with the VPSC model to create a fully computational route for predicting textures from machining.
