Tolerances in CNC Machining: How Tight Can You Go?
Understanding CNC Machining Tolerances In CNC (Computer Numerical Control) machining, tolerance refers to the permissible variation in the dimensions of a manufactured part. It’s the allowable deviation from the specified or nominal dimension. Expressed as a range (e.g., ±0.005 inches), tolerance dictates the acceptable limits of accuracy for a part to function correctly. Without tolerances,…
