WebThe best and fastest method for checking plate flatness is the use of a Flatness Gauge. This consists of a dial indicator (calibrated to 0.001mm) supported on three points and set to zero on a known flat test piece. The gauge can be used to take readings over several areas of the Lapping Plate. WebFlatness – The condition of a surface having all elements in one plane. Parallelism – The condition of a surface, line, or axis which is equidistant at all from a datum plane or axis. It's not rocket science. ... Flatness is a feature compared to itself, while parallelism requires that a feature be compared to a datum. Think of a table with two

WebIn application, one way to physically measure flatness is to use a height gage, as we can see in Figure 2. To use the height gage correctly, the part to be measured is first placed upon 3 columns with adjustable heights. Then, the height gage is run across the surface while looking at the amplitude of the needle.
