Variable fixture gages provide a quantitative value for the part characteristic being checked. For example, if the nominal dimension for a machined part diameter is 1.150″, variable-type gages can give a numerical measurement that indicates exactly how close a measured piece is to nominal. The measured value can be compared to the specification limits, which helps in qualitative decision making about the machined characteristic. These gages provide a flexible and ergonomic means to inspect the part. The fixture provides the necessary locations so the gaging units, using electronic columns, electronic probes, or indicators can be applied to specific features of the part.
