Entering Assemblies and Parts
Perform the following steps to enter a new assembly and its parts:
1. In the System Tree Items table, select Hard Disk Assembly .
2. Select > . A new assembly is inserted at the same level as the selected assembly.
If you had inserted a child assembly, it would have been inserted one level lower than the selected assembly.
3. For Name, enter My Demo Assembly for the new assembly.
4. In the Parts Table, which currently shows no parts for this newly inserted assembly, do the following in the blank row:
a. For Name, leave it blank.
b. For Part Number, enter ABC and press Tab.
The first time that you enter a part number, all enabled Prediction Parts Libraries are initialized for searching. If you are using a licensed version, this might take a moment or so.
c. If not already selected, for Part Classification, select General.
d. For Category, select Integrated Circuit.
e. For Subcategory, select Logic, CGA or ASIC.
f. For Reference Designator, enter U27.
5. Select the Prediction Data pane.
All part parameters are blank or show one or more number signs (#). To compute a failure rate, default values are stored for required parameters.
6. Click Defaults.
A number of parameters are now filled in with values. These values represent average values for these parameters. The calculation engine uses these average values if you do not enter specific data values.
Because Windchill Prediction uses average values for the part to produce a preliminary failure rate estimate, using these default values is a good way to start your analysis. As data becomes available, you can go back and enter it in the Prediction Data pane.
7. Click Defaults again to hide the default values from view.
The Defaults button is there only for informational purposes. During calculations, Windchill Prediction automatically uses the default values for parameters in which you do not enter values. You do not need to click Defaults to have this occur.
8. Click Pi Factors to see the computed failure rate of your newly inserted part.
9. Click Close to close the Pi Factors window.
