Tolerances in Sheet Metal Fabrications & CNC Manufacturing
Fifty years ago, "build-to-order" sheet metal tolerances were +/-.06" (1.5mm), primarily due to the accuracy of the equipment. Today, normal production tolerances are around 10% of that. In the following article, we are discussing tolerance ranges that are "reasonable" or "practical". If tighter tolerances are needed, they can be achieved with dedicated tooling and special processing. The most significant improvement has been in the machinery. Some modern high speed equipment can position within .0028" (.07mm) and repeat within .002" (.05mm). Materials and methods continue to play a role in the limits of precision, however. They greatly influence practical considerations for tolerances between holes (hole-to-hole), between folds (fold-to-fold), and so forth.
