Profile Tolerance

Profile tolerance is a manufacturing specification that controls the shape and contour of a part’s surface. It defines the allowable deviation from a designed profile, ensuring the part’s surface maintains proper form and fit with other components. Essentially, it sets limits on how much the actual surface can differ from the intended design to ensure functionality, quality, and proper assembly, without requiring the surface to be perfectly exact. This helps manufacturers produce parts that meet quality standards while accommodating minor variations inherent in the manufacturing process.
