WebThe involute system was invented before generating machines were available. The old method of cutting in-volute teeth with a formed cutter demanded close adher-ence to the pitch-diameter for which the cutter was made in order to reproduce the desired tooth-form. The gear books of that time emphasized the maintaining of the pitch-diameter. simplifying exponent expressions worksheet https://jpasca.com
