The examination of the surface morphology of copper, aluminum, and steel chips produced by standard shop machining processes through the use of scanning electron microscopy has led to a more fundamental understanding of large strain plastic deformation processes. The interpretation of these findings is discussed in terms of well documented dislocation mechanisms typically associated with tensile and compression deformation of metal crystals. The effect that such investigations will have on the true understanding of the mechanisms involved in plastic deformation processes is noted.
