• Ding, in manufacturing, a dimensional defect in a manufactured part's surface, in which the surface is depressed in a very small area and is usually raised in the immediately surrounding area, due to material deformation caused by the (usually inadvertent or accidental) impact of a blunt object, such as a tool or other manufacturing accessory. The defect may be unimportant or may be a critical defect that would cause unacceptable leakage, friction, poor fit, and/or cosmetic unattractiveness in the manufactured product. Detection of dings requires high-definition metrology of the entire critical surface areas of a manufactured part, since occurrence of dings is largely unpredictable as to their cause, frequency or location on the manufactured surfaces.
