MEASUREMENT TOLERANCE

_______________

One of the first things a new engineer or product designer needs to learn is the concept of measurement tolerance.

This refers to the acceptable range of variation or error allowed in a measurement. It represents the maximum allowable difference between the measured value and the true or target value.

Tolerances are essential in manufacturing and engineering to ensure that products meet quality standards while accounting for inevitable variations in the manufacturing process.

Tolerances are typically expressed as a range or deviation from the desired measurement, such as +/- 0.01 inches for a specific dimension on a part. Tight tolerances require greater precision, while looser tolerances allow for more variation but may still meet acceptable quality criteria.

This knowledge will help keep the engineer or designer from wasting manufacturing time and money on maintaining tight tolerances where they are not needed.
