New inline-inspection applications are being developed for industry thanks to advances in high-speed, low-coherence interferometry, a high-resolution three-dimensional (3D) imaging technology. Precision bore holes, for example, must adhere to strict geometric dimensioning and tolerancing (GD&T), including straightness, cylindricity, circularity, taper, distortion, runout, roughness characteristics, semi-transparent coating thickness, or defect characterization. Also, features on the insides of bores, such as threads, O-ring grooves, undercuts, chambers, and cross-holes, must often be characterized with high precision to ensure that components ultimately interlock, seal, fit, or otherwise function as intended.

Understanding this, Novacam Technologies has developed a system, dubbed BoreInspect, that provides fast, micron-precision, non-contact measurements of bore internal diameter (ID) surfaces.

Vuk Bartulovic, President of Novacam, says "By the time they come to us, many of our clients have spent a long time looking for a way to measure, in a non-contact manner, internal diameters of bores, cylinders, and other such hard-to-reach spaces. These bore diameters range from a few millimeters to as large as truck engine cylinder bores. Typically, they want to acquire full internal diameter dimensions, detect defects, and measure roughness. It is a revelation to them that an instrument exists that can provide all this functionality … and that micron-precision data on their bore ID can be acquired in a matter of seconds and in a non-contact manner."
