What can happen when we use an accuracy specification and assume all the measurements are centered in relation to the specification limits? It is a typical problem in the metrology community, where many papers assume a centered process or Measurement. When the Measurement deviates from the true value, it is said to have a bias […]
Load Cell Loading: Thread Engagement Errors Morehouse has covered this topic in previous videos and blogs. However, it is important enough to write another blog about thread engagement. Why is it important? In a typical female thread design, the modeling is done with “assumptions” on the thread engagement. A standard rule is to assume the […]
Force Measurement Error – Time Interval Between Two Successive Loadings Has anyone ever wondered if there is a difference in calibration results if the time interval between two successive loadings is changed? Is faster better and does it matter if the calibration takes 10 minutes on an automated machine pictured in Figure 2 below, or […]
