    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.
