Dimensional Optical Metrology and Inspection for Practical Applications VIII.
This report evaluates some of the challenges faced with 2D camera based on-machine metrology and potential options with using 3D sensors for such Direct Write applications. Specifically, in order to fully exploit 3D direct write technology to surface

Visual Inspection is the most common means for inspecting manufactured parts for random defects such as pits, scratches, breaks, corrosion or general wear. The reason for the need for visual inspection is the very random nature of what might be a def

The making of composite parts involves laying down multiple layers of tape in an organized manner. Misplaced ends, wrinkles or other factors can cause the part being built to have weaknesses or other imperfections. However, the actual edges of the ta

One form of additive manufacturing is to use a laser to generate a melt pool from powdered metal that is sprayed from a nozzle. The laser net-shape machining system builds the part a layer at a time by following a predetermined path. However, because

Due to the high temperatures and stresses present in the high-pressure section of a gas turbine, the airfoils experience creep or radial stretching. Nowadays manufacturers are putting in place condition-based maintenance programs in which the conditi

Characterization of a surface shape and finish has been vital for the manufacture of precision parts. Overall profile, surface finish and waviness of a part can be measured in two ways, contact and non-contact. In the contact method a stylus is dragg

Measurement of surface finish in industrial manufacturing has traditionally been done by means of either visual comparison with reference plates or by the use of contact stylus based profilers. There are many challenges associated with contact profil

Pattern projection using physical gratings or interference effects has successfully been used to perform 3D measurements of parts. However, such systems lack the flexibility to adjust light levels over the area illuminated, leaving some areas too dar
