Texture evolution in material under surface created during Plane Strain Machining (PSM) in a host of machine relevant thermomechanical conditions was studied and comparison was made with textures in the corresponding chips. By analyzing Orientation Distribution Functions, it was shown that the texture in material under surface comprised of three prominent and distinct fibers. Subsequently by analyzing the pole figures of chips and material under the surface, it was shown that the two textures have several common features with the differences lying predominantly in orientation distribution uniformity along the fibers. By in-situ characterization of deformation histories during PSM and using the Visco-Plastic Self-Consistent model, pole figures in the chip and material under the surface were predicted. Subsequently by setting up a Finite Element Model of PSM and coupling with the VPSC model, a system for predicting textures in PSM surfaces was setup. Some limitations of the VPSC model were highlighted.
