Using the Design of Experiments Tool  

This task explains how to use the DOE tool. In the scenario detailed below, you optimize a pad.
For more information about the Design of Experiments Tool, see Introducing and Describing the Design of Experiments Window.

  1. Open the KwoDesignOfExperiments.CATPart file and access the Product Engineering Optimizer workbench (Start > Knowledgeware).

  2. Click the Design of Experiments icon (). The Design of Experiments window opens.

  3. Click to select the input parameters.

  4. In the opening dialog box, select the OzLength, OxLength, OyLength parameters, move them to the Selected parameters column by using the button and click OK

  5. In the Select input parameters field, select the OzLength parameter and click . Enter the following data in the dialog box and click OK.

Inferior Range 20
Superior Range 120
Number of Levels 6
  1. Apply the following values to the OxLength parameter:

Inferior Range 30mm
Superior Range 150mm
Number of Levels 10
  1. Apply the following values to the OyLength parameter:

Inferior Range 10mm
Superior Range 100mm
Number of Levels 4
  1. In the Select output parameters field, click to select the output parameters.

  2. In the opening dialog box, select the OxyArea, and the PadVolume parameters by using the button and click OK

  3. Check the Save curves in the output file and click to launch the analysis. 

  4. Enter the name of the output file and click Save. The analysis starts and a dialog box identical to the one below is displayed.

     
  1. When the analysis is finished, select the Results tab. The number of results appearing in the Table of Experiments matches the number of updates (see Settings tab). 

    You can apply the values of the table to the parameters. To do so, select one line in the Table of Experiments and click Apply these values.

  2. In the Select one curve scrolling list, select Plot mean effect of 'Oy Length' on the output : PadVolume. The following graphic is displayed (click the graphic below to enlarge it):
