Calibration /ˌkælɪˈbreɪʃən/ – 1) in metrology – making corrections or detecting errors for a set of measurements (eg, a set of balance stones). 2) In rolling production K. – metal rods, similar, etc. passing the rolled profiles through the hole of the cold rolling mill and giving them precise dimensions. 3) K.- treatment of holes in order to increase the accuracy of the shapes and sizes of the holes, as well as to reduce roughness on their surfaces and to strengthen the surface layer after cutting; it is done by dipping a steel ball or by inserting a polished thicker tool (at the same time, a mandrel).
Ex. Before operating new drilling equipment at a mining company’s mine, engineers carefully calibrate depth gauges and pressure sensors to ensure accurate measurements of borehole depth and groundwater pressure. This calibration process optimizes equipment performance and improves the efficiency of the mining process.
