• It is considered invalid.

• It defaults to zero tolerance.

Is it possible to manufacture parts without some variation?

• Yes

• No

• Only in certain conditions

• It depends on the material

What happens if the tolerance is reduced?

• Costs go up

• Costs go down

• No change in costs

• Quality improves
