To address the traditional limitations of conventional methods, Arrow Gear implemented a highly advanced system for performing contact pattern development – a system that provides a dramatic reduction in the time and expense of the process when compared to conventional methods. This system uses a combination of state-of-the-art development software and machine tools. Among its key components are Gleason’s G-AGE, CAGE, MINIGAGE, Loaded TCA and Finite Element Analysis software packages. And for machine tools, the system utilizes Gleason Phoenix CNC Tooth Cutters and Phoenix CNC Tooth Grinders, in conjunction with a Zeiss Hofler CNC Gear Inspection System. More detailed information on the use of this system will follow, but here are a few highlights of its capabilities. Using the
development software, engineers can build virtual models to predict how
In essence, this system eliminates the trial and error process that was once required. And the bottom line is that development time is reduced and the gear producer is able to provide a significant cost savings to the customer. An interesting footnote on this system, is that Arrow was the first gear manufacturer in the world to utilize this type of comprehensive or Closed Loop system. Today, only Arrow Gear and Gleason have this system under one roof. |

the gear will perform in actual operation. This in turn generates the
settings to be used by the machine tools. In addition, these settings for
the machine adjustments are automatically downloaded to the machine tools,
greatly reducing the time spent on setup. Perhaps the most dramatic aspect
of this system is that ideal settings of the machine tools which are
required to produce the desired contact pattern are typically achieved in
the first or second attempt on the gear manufacturer’s shop floor.
