Hobbing - Wikipedia
Hobbing is a machining process for gear cutting, cutting splines, and cutting sprockets using a hobbing machine, a specialized milling machine. The teeth or splines of the gear are progressively cut into the material (such as a flat, cylindrical piece of metal or thermoset plastic) by a series of cuts made by a cutting tool called a hob .
Spline Cutting - Helios Gear Products
Tooth profiles of external splines can be cut by shaping, hobbing, form-milling, or power-skiving. The hobbing process typically offers the best balance between productivity and flexibility. However, due to sweepout clearances and tight part features, shaping methods are also commonly used.

InvoMilling™ is a process for machining external gears, splines and straight bevel gears that allows for in-house gear milling in standard machines. By changing the CNC program instead of changing the tool, one tool set can be used for many gear profiles.
The reason for the involute profile is the fact that most external splines are manufactured by hobbing with a standard straight-sided, symmetric hob tooth profile that is fast and delivers good accuracy results. The internal spline has to be manufactured with shaping or broaching, using an involute cut-ting tooth profile.

Apr 18, 2016 · There are a number of decisions the manufacturing engineer faces when planning the necessary processes for producing parallel axis, cylindrical spur or helical gears and splines. Hobbing, of course, is the most common metal-removal process to create the proper tooth space that is needed to produce these gears.

Jan 1, 2005 · Hobbing: All types of external splines can be produced with the hobbing method. A cylindrical hob with the mating rack form of the spline to be produced is the cutting tool. The number of starts of the hob and the number of teeth in the spline determine the ratio that the hobbing machine is geared to produce.
