A method for chemical milling a workpiece utilizing a chemical milling fluid that is passivating to the workpiece, wherein the tool is provided with an abrasive surface, and said tool and workpiece are brought together with a contacting relative motion so that said abrasive surface will selectively abrade the workpiece to remove any passivation layer therefrom in those areas to be machined and such that the unabraded surface areas will retain the passivation layer to prevent chemical milling thereof, and a reciprocal motion between the tool and workpiece is also effected to pump the chemical milling fluid through the gap between the tool and workpiece and prevent reduction of the milling rate of the milling fluid. |
