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.[3][4] 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.[5](DFI)
