When do I need a differential-equipped gear hob?
FAQ about gear cutting, gear software and gear designPrimarily, when you need to recut helical gears. The differential allows you to keep the workpiece and hob cutter in sync while you back the cutter up for another cut. This is particularly handy for "getting it right" the first time, larger pitches, and some harder materials. Also, with a little trickery you can cut prime spur gears with large tooth numbers. See How to cut a large spur gear with a prime number of teeth? for a description of a method for large prime gears.
Related QuestionsWhat can I cut on a non-differential gear hob?
FAQ about gear cutting, gear software and gear designA hobbing machine in its simplest form has no differential, yet it is versatile and productive. A basic non-differential gear hob can serve well for break-down and production work over a wide variety of toothed members. The type of work generated is determined by the hob cutter tooling. Hob cutters are readily available to cut nearly any external tooth member: spur or helical gearing, splines, timing belt pulleys, roller chain or silent chain sprockets, and throated worm gears.
Related QuestionsWhat is the Differential Factor required in CPC-HOB?
FAQ about gear cutting, gear software and gear designDifferential Factor as used by CPC-HOB should not be confused with the machine's Lead Constant. Differential Factor is used by CPC-HOB to accommodate the Index Constant on some hobbing machines that changes when the differential is locked or unlocked. CPC-HOB automatically compensates for changing Index Constant when the Diff Factor (DF) is entered. The Index Constant for most machines is constant and independent of differential engagement.
Related QuestionsWhy does CPC-HOB find index gear sets too small to reach?
FAQ about gear cutting, gear software and gear designCPC-HOB selects suitable index gear sets based on index gear NDP and center-to-center (C-C) distance between fixed index gear shafts. These are user-specified values entered for each machine in CPC-HOB's Hob Machine List. If C-C distance is too small, or if the NDP entered is smaller than actual index gear pitch, then CPC-HOB thinks smaller size gearsets will fit together on the machine.
Related QuestionsHow is a non-differential hobbing machine set up to cut a spur gear?
FAQ about gear cutting, gear software and gear designAll gear hobbing machines have an Index Constant. This constant, along with the number of teeth to cut and the number of starts in the hob cutter determine the index gear ratio and the index change gears. Some typical Index Constants are: 36, 30, 24, 15, 12, 10, etc. Let's take an example using a single start hob cutter.

Draft rec.boats.cruising FAQWhen the US defence department developed the GPS satellite system, it was meant for military applications - to help pinpoint the exact position of a soldier in the field, for example. That system is extremely accurate, within something like 50 feet. The DoD didn't want to give that capability to the enemy, so they scrambled that signal. The signal that's available to the public has been deliberately tweaked to provide a position within about 200 feet.
