Webbetween the gear teeth similar to milling. Gear teeth are normally manufactured with pressure angles ranging from 14.5 ° to 25 °. As the pressure angle increases, the teeth become wider at the base and narrower at the tip. This makes the teeth stronger and able to carry more load but more apt to chip at the tip if not properly designed.
