Hope all might be known about tolerances.

While dimensioning a PART/COMPONENT, we’ll give tolerance value as a limit to manufacturer. If the tolerance value specified inside the parenthesis, what does it mean....

To put it in a nutshell, what is the difference between giving a tolerance with parenthesis & without parenthesis.

For eg.
Dia 30 + or - 0.1

Dia 30 (+ or - 0.1)

Please refer the attached tol.bmp file for clarification.

Cheers,

Manavalan

Parathesis are used with dimensions on engineering drawings to indicate that the value is for reference only. A dimension without parathesis indicates that the dimensional limits do apply.
