Tolerances, Engineering Design & Limits & Fits
(This calculator requires a
java  enabled browser)
This calculator calculates position tolerances utilizing principles and concepts within ASME Y14.52009 and ASME Y14.5M  1994, Geometric Dimensioning and Tolerancing (GD&T).
For the equations behind this calculator, see:

Interpretation and Application of
Geometric Dimensioning and Tolerancing
Open Spherical True Position Calculator
This calculator will
convert coordinate measurements to position tolerances.
Three (3) inputs
are required, See the application illustration at bottom of page.
The following are definitions for the elements:
X Offset  This is the difference between the
basic dimension (Drawing) and the actual measurement of the produced part in the X axis direction.
Y Offset
 This is the difference between the basic dimension (Drawing) and the actual
measurement of the produced part in the Y axis direction.
Z Offset  This is the difference between the basic dimension (Drawing) and the actual measurement of the produced part in the Z axis direction.
Calculated (ACTUAL) Radius True Position  The calculated radius offset
see Spherical True Position Calculator .
Calculated (ACTUAL) Spherical True Position  The calculated spherical positional tolerance
diameter zone (2 x R).
