  • Similarly, if there is dirt or grease in the contact area between the anvil and the elevating screw or the elevating screw mechanism itself this will cause excess deflection and change the hardness reading. (buehler.com)
  • Repeatability
  • Tests of Gauge Repeatability and Reproducibility (GR&R) can show the degree to which machine variability takes up the available process tolerance. (buehler.com)
  • The grain sizing software providesquick and reliable test results, with high repeatability and reproducibility.The ZHVµ-A has been a cost effective solution for both hardness testing andmetallographic Analysis. (zwick.co.in)

  • One of our big focuses right now is both developing and selling the automatic products," says Bill O'Neill, Americas sales manager for hardness products at Wilson Instruments/Instron. (qualitymag.com)
  • results
  • Variability in test results is the sum of the variability from the equipment and variability from the operator and environmental conditions. (buehler.com)
  • High variability (or a narrow process tolerance) results in high GR&R. A GR&R test on different equipment used for the same process allows the user to directly compare the in-built variability of the machine values (the lower the GR&R value, the better the performance of the equipment), see Figure 23.5.
