Gear manufacturing process applies cutting tools to base metal simultaneously

摘要

In a process to manufacture gears e.g. worm drives or gear wheels (1,5,6,19,21), the metal blanks are machined in a continual cutting process. The cutting tools (32,34) are applied simultaneously at a number of different points on the blanks and to the developing tooth flanks. The cutting process applies the cutting tools continually to each blank; not by repeated application, withdrawal and re-application of the tools. All the teeth may be the same as each other.
