How do you interpret tolerances?

Tolerances refer to the permissible limits of variation in a physical dimension or measurement, ensuring that parts fit and function correctly within specified parameters. They are crucial in engineering and manufacturing to maintain quality and performance standards. Tolerances can be expressed as absolute values (e.g., ±0.01 mm) or as a percentage of the nominal dimension, and interpreting them correctly is essential for ensuring that components assemble properly and operate as intended. Understanding tolerances helps prevent issues like misalignment or mechanical failure.
