Machining Features that Aren't Really There

摘要

ETJ Corp. (Austin, TX) is a small precision manufacturing company that is having good success in using CAM to develop manufacturing processes to machine replacement wing flap tracks for the US Air Force's 40 year-old, C-5 transport plane. Within recent months, the company has submitted first articles and the required certified process documentation for three versions of the flap tracks. Two of them have been approved and approval is expected on the third configuration. These approvals will make ETJ one of four or five companies that have been approved to manufacture these deceptively simple-looking parts.
