Gear grinding is a hard finishing method for gears, using tools with a specific geometrical profile. It is divided into two main groups: generating grinding and profile grinding, relating to the manufacturing of the tooth flank. Furthermore, these groups can be subdivided into continuous and discontinuous processes (DIN 8589).

Flutes / teeth: The flutes of the milling bit are the deep helical grooves running up the cutter, while the sharp blade along the edge of the flute is known as the tooth. The tooth cuts the material, and chips of this material are pulled up the flute by the rotation of the cutter. ... Modular principle A face mill shell. The rectangular cutout ...

The tool reciprocates parallel to the center axis of the blank and cuts one tooth space at a time. Successive teeth are cut by rotating the gear blank through an angle corresponding to the pitch of the teeth until all the tooth spaces have been cut. Fig. illustrates the principle of cutting gear teeth by means of a shaper.

1) For high stability and performance, select thread mills with a lefthand helix flute design, requiring a lefthand spindle rotation. The combination of lefthand cutting geometry used in a conventional milling cutting path, entering the hole and threading from the outside in or from toptobottom, creates a very stable cutting action for this interrupted thread cutting process.

For parts having DP10 and larger tooth forms, inserted cutters are possible to apply. There are advantages to using inserted tools for larger tooth forms. Solid carbide tools especially are increasingly costly, and damage to one tooth in a solid cutter usually means scrapping it, while a damaged insert can be changed (see Figure 3).

Heavyduty plain mills have few but coarse teeth, designed for heavy cuts. Why are plain milling cutters not used to mill steps or grooves. Plain milling cutters do not have side cutting teeth. This would cause extreme rubbing if used to mill steps or grooves. Plain milling cutters should be wider than the flat surface they are machining.
