Figure 1Įxample: Six parts are submitted for study. Linearity reveals the accuracy of the gage throughout a range of measurements. The slope generated by point cloud measurements with respect to each reference dimension will determine the linearity of the measurement system. The study looks at the bias for each part and how it changes from part to part with respect to these reference values. Master Reference values must be obtained for all measurements. This is the same as the Bias study but with several different parts of different size spanning the applied application range of the gage. Without a reference value – the sampling is nothing more than a repeatability study. A reference measurement must be first taken to a known standard with significant accuracy. How many? At least (10), but more are preferred. A (Type 1 Gage Study) requires repeated measurements of the same part, by one person. Bias will tell you how accurate the gage is with respect to a master reference. Example: an operator uses a gage in a consistent manner, and every time it repeats the measurement value to an upper or lower side with respect to its reference measurement. Gage Bias Studyīias is defined as: Response error introduced into the measurement such that, it always trends a certain way. After calibration and bias analyses are done, a Gage R&R study is used to quantify the inherent variation of all components comprising the measurement system selected for a task. In general, it is necessary that calibrating equipment have a level of measurement accuracy (10X) greater than that of the instrument it is calibrating. Calibration will determine a gage’s measurement to an agreed upon reference value. However, the question that must be asked is: Are the measurements good enough? Determining that answer, requires that the measuring system be calibrated against a known standard. This means that variation is random (common cause), and that measurements have appropriate resolution relative to the specified part tolerance. In order to be valid, the measurement system must be in statistical, product and process control.
