Abstract

A theory of axially symmetric cutting is used to estimate the resistance to material removal of a composite cylinder undergoing stripping of a peripheral coating. The removal of materials from the surface of the cylindrical workpiece is analyzed using the minimum energy theory of Merchant. It is assumed that the shear surface is oriented at an angle π, such that the total work done at the shear surface by relative sliding and at the rake face due to friction has a minimum value. When the material conditions and the depth of cut are the same for cuttings in the axially symmetric and orthogonal modes, chips removed in axially symmetric cutting will have an additional energy loss due to the tensile hoop stress. The resistance due to the axially symmetric cutting is therefore larger than that arising from orthogonal cutting. The predicted resistance of axially symmetric cutting are in favorable agreement with data of dynamic stripping tests performed at Sandia National Laboratories.
