Flatness measurement

Flatness measurements are performed to check the flatness of CMM tables and surface plates. It determines whether any significant peaks or troughs exist and quantifies them. If these errors are significant then remedial work, such as lapping, may be required.

How important is sheet and plate steel flatness?

Similarly, width flatness was the deviation measured across the rolling direction, again expressed in inches per foot. Overall grade flatness was an amalgam of these numbers. Length flatness showed the most marked improvement using TP-CTL (see Figure 4). With TP-CTL, flatness was improved 1.5 times in C1010 and 5.5 times in grade 80 material.
