Hobbing process: In this process the gear blank s rolled with a rotating cutter called a hob. A majority of involute gears are manufactured by this method. A hob looks like a worm but carries a number of straight flutes, cut all around, parallel to its axis. This results in the production of separate cutting teeth and cutting edges.

Ignoring the deformation of the grinding wheel, the UCT h m,i taken by the lowest point can be divided into two components: (1) The first term h m, the length of AC, is caused by the difference in the movement trajectory between the adjacent grains, which is related with the grinding parameters, grinding wheel diameter, and grain location.(2) …

Evan Doran. Associate Editor, Modern Machine Shop. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains …
