WebThe flatness tolerance is determined to ensure that a given surface is located within two imaginary, perfect, and parallel planes. In other words, the tolerance zone is between the highest and lowest acceptable points across the plane of the surface being measured. How to measure flatness WebCustomer dimensional tolerances vary, but can be as stringent as +/- .02 mm. Consistency is an integral part of producing a high quality product at Diamond Innovations. Chadwick’s team determined they could improve product repeatability, accuracy and productivity by incorporating more complete process automation.
