Except for shaping with a pinion cutter above all used for external gear cutters, shaping with a pinion cutter is used for internal gear cutters.

How internal gears are being made by the tapping process? Please explain it in detail.

An internal gear having one side blind is produce by pinion cutter. And broaching is done on hollow internal gear. Broaching is more economical and fast then shaping by pinion cutter.

Also known as broaching.

Spur gear can not be made with the hobbing process. Only using with shaping with pinion cutter.

Hobbing is the right answer.

The internal gear is a gear with its teeth cut in the internal surface of a cylinder and meshes with spur gears. In its manufacturing, because of its shape, the usual hobbing machine used in spur gear production cannot be used. Generally, it is made with gear shaper (or gear shaping machine) equipped with a pinion cutter.
