real time—the busy machine shop or large produc-
tion department stays flexible using this hard scudding
technology. In some cases, this technology is applicable
on near net, pre-hardened gear blanks, allowing signifi-
cant step reductions in the manufacturing process.
In operation, when cutting 0.006" to 0.0010" per flank
on a tooth, the hard scudding process can be used on
carburized or through-hardened parts; nitriding generally
does not provide enough case depth to ensure sufficient
stock for clean-up. An automotive ring gear, for example,
which requires 40 to 50 seconds for scudding, can be hard
scudded in 25-30 seconds. is process development
stands as a viable and cost-effective alternative to conven-
tional grind-and-hone operations, yielding an attractive
cost per piece and extended tool life. e added benefits
of reduced capital outlay, and a significantly more consis-
tent end product bode well for the automotive powertrain
and other gear market segments.
