ABSTRACT:
A method for producing a cutting blade comprising the steps of obtaining a cutter head having a plurality of blade-receiving slots formed in a face thereof, positioning the cutter head in coordinate measuring machine, and inspecting a selected one of the slots using the coordinate measuring machine. Data obtained during the inspecting step is recorded on a recording medium transmitted to a computer of a numerical control grinding machine. A cutting blade blank is positioned in and ground by the computer numerical control grinding machine. The grinding step comprises the steps of generating selected finished surfaces of the cutting blade from the cutting blade blank and compensating for dimensional variations of the inspection data of the selected slot relative to dimensional design requirements of the selected slot. A plurality of the blades produced in this manner may be assembled in a cutter head so as to produce a trued face hobbing cutter head which in turn may be utilized in conjunction with a gear cutting machine to make a spiral bevel, zerol, or hypoid gear.
