WebFigure 4. Surface with a GD&T flatness tolerance of 0.57 units. Let’s look at an example. We have a surface with a GD&T flatness tolerance of 0.57 units (Figure 4). In the digital realm, if you are taking measurements with a CMM (portable or otherwise), then the software has two methods of evaluating flatness: Best Fit or Minimum Zone. Figure 5. WebTesting for flatness Take 5 small, identical pieces of steel and grind them flat and to the same thickness. Then place them in the four corners of the chuck, as well as in the center. Carefully grind both sides and check them on the surface plate with a dial indicator. Be sure to mark the pieces so you know where they were on the chuck.
