Quality related in-process inspection/verification is an essential part of quality control in manufacturing.
Inspection in manufacturing includes measuring, examining, testing, or gauging one or more characteristics of a product or process and comparing the results with specified requirements to determine whether is the requirements are met for each characteristic. Common examples of inspection by measurement or gauging include using a caliper or micrometer to determine if a machined dimension of a manufactured part is within the dimensional tolerance specified in a drawing for that part, and is thus acceptable for use.
Design for Inspection (DFI) is a concept that should complement and work in collaboration with Design for Manufacturability (DFM) and Design for Assembly (DMA) to reduce product manufacturing cost and increase manufacturing practicality.
Photogrammetry is a modern way of visual inspection, delivering high accuracy and traceability for various industries. The portable 3D system is a versatile optical coordinate measuring machine (CMM) with a wide range of capabilities. Highly accurate point measurements can be taken with inspection carried out directly to CAD models, geometry or drawings.(DFI)
