Worm Gear Cutting - August 2016

The article "Worm Gear Cutting" appeared in the August 2016 issue of Power Transmission Engineering.

I have a fairly straightforward question about a worm gear segment. But as of yet, I havenít gotten a straight answer from any of the gear job shops Iíve approached about this job. Is there a "traditional" gear cutting method that can produce a ~180 degree enveloping worm gear segment when a feature on the back of the part will interfere with a complete rotation of the part? Or am I left with only the option of 4- or 5-axis surfacing with a CNC mill? I have presented this part to several well-known gear shops in the U.S. without a straight answer on how the part can be made. Any help you could offer would be appreciated.
