A Tolerance Has a Price
Tighter is not automatically better. Every unnecessary micron can demand more capable machines, slower cycles, more inspection and more scrap. Manufacturing engineering connects design precision to the process capability actually required by function.
Scenario: A Part Keeps Failing Inspection
Check whether the process is centred, whether tooling is wearing, whether measurement is capable, and whether the tolerance itself reflects functional need. A quality problem can originate in the process, the gauge, the material or the design requirement.
