The gauge (gauge) cannot indicate the measurement value, and can only judge whether the measured length is qualified according to the fit clearance with the measured piece, the light transmission degree or whether the measured piece can pass through the measured piece and the like. The gauges control the upper and lower limits of the size or gauge, and generally comprise all tolerance bands with simple gauges, usually solid bodies of precise size and shape, such as cones, cylinders, block plates, rulers, screws, and the like. Commonly used gauges include gauge blocks, angle gauge blocks, polygonal prisms, sine gauges, straightedges, flat gauges, flat plates, feeler gauges, flat crystals, limit gauges, and the like. The checking of the workpiece by the gauge usually includes a normal method (the size of the workpiece is controlled by using a through end and a stop end of the gauge so as not to exceed a tolerance band), a coloring method (a thin layer of pigment is coated on a working surface of the gauge, the surface of the gauge is lapped with a measured surface, and the coloring area size and the distribution unevenness of the measured surface represent the error), an optical gap method (the measured surface is contacted with a measuring surface of the gauge, a light source is placed behind the measured surface or natural light is adopted, the size of the gap can be judged according to the light transmission color so as to represent the size, the shape or the position error of the measured surface) and an indicating method (the accurate geometric shape of the gauge is compared with the geometric shape of the measured surface so as to indicate the error of the measured geometric shape by using a dial gauge or a micrometer and the like).
