What Are Tolerances?

In short, tolerances are measurements that signify the level of precision needed for a part that you want to manufacture. Specifically, machining tolerances indicate the degree of variation permitted in a part’s final dimensions or measured value.

Machinists measure machining tolerances by numerical values, typically preceded with a ± symbol. For example, you may assign a tolerance of ±0.001″ to a part measuring 2.550 inches in length. This would indicate that the manufactured part would have a variable length measuring between 2.549” and 2.551”. If a part measuring 1.5 inches in height needs a tolerance of ±0.005”, the final part should fall into the range of 1.495” and 1.505” to pass quality inspection.

Specified machining tolerances tell manufacturers and CNC machining services what degree of precision to use when producing a part. The smaller the tolerance—in the manufacturing world this is a tighter tolerance—the more precision required. The larger the tolerance—also called looser—the less precision you need.

Things to Keep in Mind when Choosing Tolerances

One of the key things in determining the right CNC machining tolerances is figuring out at what point a part’s function and performance will be affected by a variation in dimension or size. Some types of parts, like critical components in engines, require a high degree of precision and any lapse in geometric form could have serious consequences. Other types of parts might not require the same degree of precision, and a slightly larger manufacturing deviation will not affect them.
