Visual inspection in all dimensions

Visual inspection specialists, General Inspection, based in Davisburg, Michigan, have installed another Gi-100DT automated inspection system (AIS), this time in California, for a large manufacturer of precision aerospace fasteners. 

This Gi-100DT is equipped with a total of six cameras providing complete dimensional inspection, internal and external visual defect detection, top and bottom surface inspection for a full range of turned aerospace collars.

When it comes to dimensional inspection, the Gi-100DT comes standard with three cameras, one from the side, one from the bottom and one from the top. The side camera measures all profile features including threads, lengths, diameters, and angles. The top and bottom cameras measure OD, ID, roundness, and concentricity. Parts are measured to print specifications through Gi’s user friendly software, each dimension is saved and recalled by part number.

In addition to the dimensional inspection, the Gi-100DT also detects surface defects on the top, bottom, and inner diameters. The surface defects include dents, scratches, chatter, pitting, and chips. This system is equipped with three additional cameras each with patented optics positioned above and below the parts to detect internal and external visual defects. Defects such as damaged ID threads, cracks, burrs, dents, and other damage are detected using Gi’s sophisticated algorithms, advanced lighting techniques, and a special, unobstructed part view handling technique.

One of the many advantages of the Gi-100DT is the flexibility to handle a wide range of parts combined with the fastest part to part changeover. Each of the six cameras, the part confinement, and the dial table speed are servo controlled. An operator simply selects the appropriate part number and all adjustments are automatic removing human subjectivity. 

After searching the world for an inspection system with complete dimensional and visual defect detection capabilities the Californian manufacturer selected Gi. Defect detection, fast changeover, and inspection rates (minimum of 300 parts per minute) were the deciding factors in its choice of supplier.
