Guideline 3: Optimize the design for production.

Provide dimension, tolerance and precision values

that can be manufactured and inspected.
1 x 45°--..

• Check precision on linear, diameter and

angular dimensions. Additional non-needed

decimal places increase cost to a part. Tolerance

+/- _50

Example:

The dimension 45 at +/- .5° indicates the

dimension is machined between 44.5° and 45.5.

The dimension 45.00 at +/- .05° indicates the

1 .00 X 45.00 °~
dimension is machined between 44.95 and 45.05.

This range of values adds additional machining

time and cost to the final product.

Modify the dimension decimal display in the

Tolerance/Precision box in the part, assembly or

drawing.
