Abstract: Systems and method for tool path approximation may comprise approximating the outer surface of a part to be worked. The outer surface may be approximated by a plurality of airfoils. Moreover, the system and methods approximate a tool path based on a cutting tool and convert the tool path to accommodate a non-cutting processing tool. The tool path may be implemented on a computer numerically controlled machine that is configured to control a flexible fork peening tool.

Abstract: An estimated force applied by a milling tool at a surface point of a component is determined during milling operations of the component. An estimated deflection of the component associated with the estimated force is determined using the estimated force and a compliance tensor of the component corresponding to the surface point of the component. The estimated deflection of the component is compared to one or more deflection criteria. A feed rate of the milling tool is adjusted during the milling operations of the component based on results of the comparing.
