Tolerancing
Use the following steps to apply an X Y Positional Tolerance and Diameter Size tolerance to a measured circle:
• Step 1: Skew and datum your part. • Step 2: For this example measure the circle that you want to apply the tolerance to. • Step 3: While in the feature detail screen, press the tolerance button( ).
• Step 4: You will now be looking at the Nominal Entry Screen, as indicated by the orange highlight on “NOM”. • Step 5: Select the X axis field, it will turn orange. Use the numeric keypad to enter the nominal dimension for X. • Step 6: Do the same for Y and Diameter. Pro-Tip: In most cases the measured dimension will be close to the blue print nominal dimension. As such a digit typically just needs to be “rounded”. If the dimension is displayed as 5.013, and should be 5.010, simply press the “1” , this will round the 3 to 0, quickly setting the desired nominal value.
Pro-Tip: if you select the last digit of a nominal value using the touch screen, moving your finger left and right will index the value up and down until the desired value is reached.
• Step 7: Once your nominals are specified, press the “TOL” key, then press the Add Tolerance Button ( ). You can now select the tolerance types you would like to add. In the example below a cartesian tolerance for X and Y have been added as well as a size tolerance for the Diameter. When adding tolerances the -TOL and +TOL columns for each coefficient will be added. • Step 8: Select the -TOL for the X tolerance , and enter .010. Do the same for the + TOL and for the Diameter. You can use the keypads directional arrows to move through the fields. (Upper and Lower limit display can be toggled by pressing the column header area). Pro-Tip: When all of the limits will be the same, in this case .010, after you enter .010 in the field for -TOL, a field in the lower right will populate with .010. If you press the soft key next to this field in the lower right, it will auto fill the selected field with .010.
