A method for controlling flow localization in machining process is disclosed. By application of a constraint of sufficient level in the deformation zone and modifying the surface boundary conditions, suppression of unsteady flow and flow instabilities is achieved. The method enhances machined component quality by ensuring a uniform deformation state on the machined surface. Machined components are produced by ensuing uniform deformation by adopting constrained-cutting process for suppressing the instabilities and unsteady flow through a pre-determined location of the constraint of the constrained machining process relative to the machining tool.
