MIL-HDBK-204A, MILITARY HANDBOOK: DESIGN OF INSPECTION EQUIPMENT FOR DIMENSIONAL CHARACTERISTICS (30 NOV 1990)., The purpose of this handbook is to assist personnel involved in the design, procurement, or production of materiel for the Department of the Army (DA) with the selection or design of inspection equipment for dissensioned characteristics. The handbook covers three main topic areas ( 1) measuring equipment and methods, (2) gage design and use, and (3) automated and computer-aided inspection techniques. In the area of measuring equipment and methods, a discussion of the principles and applications of basic instruments includes descriptions of currently available general-purpose measuring equipment. This discussion is intended to provide some background information for personnel who may be involved in selecting measuring equipment, either for a specific purpose or for a number of different purposes. A significant portion of the handbook deals with gage design. This discussion is intended to serve as a primer and as a policy document for personnel involved in gage selection or design. The intent of including gage design policy in this handbook is to provide designers, manufacturers, and inspectors with a common reference point that will result in greater uniformity of design practice. The chapters that deal with automated and computer-aided inspection equipment are intended to identify considerations in the design and selection of such equipment.
