technologies are making slower, less reliable, traditional methods obsolete. To ensure his company's couplers, tube nuts and internal female nuts contained zero defects, Mr. Abbate turned to a high speed vision-based measuring machine called the GI-100DT from General Inspection, a developer of high speed measuring and sorting fastener inspection systems. e device uses a series of front and backlit cameras to calculate a part's height, profile, ID and OD. e device also has a number of advanced options, including cameras to check for internal threads, an axial viewer that detects surface imperfections on multiple sides of a part at once, and eddy current capability, which enables checking for metallurgical defects along with plating or hardness variations. With 360-degree internal thread inspection capability, the General Inspection device incorporates hole inspec- tion optics to specifically image and measure both the bottom of a hole and its vertical walls. is allows inspecting ID threads in detail and the detection of small defects such as weld splatter, torn threads, reamed threads, chips in threads, short or missing threads, as well as a single damaged thread. "It is the only sorting machine I have seen that has the capability to totally look inside the part," Mr. Abbate says. "e different types of special lenses on these cameras are good at looking at all the internal features, which we could never get on a machine before." :: The inspection machine does a good job of distin- guishing the interior part features from glare or shadow. The dial table-style glass top stabilizes the parts during inspection while allowing viewing of the top and bottom simultaneously. :: This circled area is one of the many defects possible on external threads. productionmachining.com :: 43 Ensuring Zero Defects in Internally Threaded Fasteners
