I was asked this question during a recent on-site visit…
QA Manager
What is an easy was to explain tolerances to new employees?
My Response
Focus on the fact that tolerances are commonly expressed in a way which can be easily broken up into simple math equations.
Dimension: 1.00 ± 0.01
Upper Limit: 1.00 + 0.01 = 1.01
Lower Limit: 1.00 – 0.01 = 0.99
Additional Thoughts
When possible break ideas into their simplest form such as an equation or concept. Keep in mind the issue is very often math not tolerances. In this case, focus the attention on basic math and calculator usage first before moving on to part tolerances.
