Metric Tolerances

What is tolerance in engineering

• Limits of variation

• Capacity to endure pain

• Permisive attitude

• Physiological resistance

What happens if the tolerance is reduced?

• Nothing changes

• Costs go up

• Costs go down

• Objects start to fit perfectly

What happens when the tolerance is not stated?

• It has to be perfect

• It has an implied tolerance

• The engineer forgot

• It should never have a tolerance

What happens when you have multiple tolerances?

• Tolerance Accumulation

• Nothing

• Cascade Errors

• You should never have more than one tolerance

Which of these is a unilateral tolerance?

Which of these is an Unilateral and Bilateral tolerance example?

• 
• 
• 
• 

Is over dimensioning good?

• Yes

• No

• Maybe

• Probably

What is interchangeability?

• Mass produced part (replacement part)

• Replaced by another object without affecting code using the object

• Similar objects

• None of the options

Is it possible to manufacture parts without some variation

• C'mon its 20th century

• Yes

• No

• Human beings are perfect, as well as our creations

Is the manufacting process a key part to choosing tolerances?

• Yes

• No

• Maybe
