Gear inspection has long been a highly specialized costly investment and an overall challenging part of the gear manufacturing process. Given that complicated gages, testers, and CNC equipment all go into creating high quality gears, companies may want to invest in a CMM to streamline inspection.
In today's production environment, a variety of different measurement devices is used to assess the quality and accuracy of workpieces. These devices include CMMs, gear checkers, form testers, roughness testers, and more. It requires a high machine investment and a high handling effort - especially if a full end-of-line measurement is needed. One approach to reduce quality costs is to include all measurements in one single machine that is suitable and robust enough for use in production.
When parts you manufacture pass through numerous processes such as deep hole drilling, machining, hobbing and grinding, a CMM is essential when your customers require 100 percent in-process and final inspection.
At Andrew Tool, CMMs have been an integral part of their manufacturing processes for years, but they had never faced a project with such intricate measurements, tight tolerances, heat treatments and a very short time frame requirement.
