Add Features To A Part (Inspection Plan)
The "Features" page can be reached by selecting any part on Part & Feature Setup page, which located on the Quality Management menu.
To learn about Updating Part Features in Bulk, see Bulk Updating Features.
Go to Adding Feature Photos to view how to add feature photos on the measurement entry screen.
To learn about sampling plans, see this article.
Expand Fullscreen
You can click the Fullscreen button to expand the Features table.
Add Feature
Click the "+ Add Feature" button to create a new feature for the part.
Bulk Update
Click after marking the checkboxes belonging to one or more features to update specific fields for all selected features simultaneously.
Show Removed Features
Mark this checkbox above the features grid to see a list of the inspection plan's removed (i.e., deleted) features.
Copy Characteristic
Click the copy icon on the right side of any characteristic row to duplicate it. (Only the new feature's Feature Number will be different from the original.)
Remove/Restore Characteristic
An "x" icon on the right side of each characteristic can be used to remove it; the "+" icon can be used to restore a feature.
**Bold = Required**
| Feature # | Unique designator for the feature. Can contain only decimal points and English alphanumeric characters. |
| SPC | Click view the feature's individual control chart. This option only shows when a feature has one or more measurements. |
| Measurement Sequence # | Order on inspection plan |
| Operation Number | Use this to define the operation number of the part. Features assigned to the same operation number will appear together when it is selected on the "Record Measurements" page. |
| Measurement Count | Number of measurements already recorded against the feature. |
| Key Feature | Used to designate the feature as key |
| In Inspection Plan | If set to "Yes", the feature will be measurable on the Record Measurements page. If set to "No", the feature will not show on the Record Measurements page. |
| Sampling Plan | See Sampling Plans |
| AQL Index | Target quality level, specified as the percentage of parts in a run that may permissibly be defective on this feature. This field is only available when the "AQL, c= 0" or "AQL, c =0 (modified)" sampling plan has been selected. In aerospace manufacturing, 1.500–4.000 are often recommended for minor defects, and 0.650– 2.500 are recommended for major defects; consult your quality manual or customer guidelines for specific instructions. If the feature is critical, then a more stringent sampling plan (such as 100%) is advised. |
| Description | Description of the feature. |
| Measurement Type |
Select an option. Selecting "Variable" type will make this feature numerical. Selecting "Attribute" will make the feature Pass/Fail. Selecting "Not Reportable" causes the feature to not require a result. This value cannot be updated once a feature has been measured. |
| Specification | Required for "Variable" features whose "In Inspection Plan" setting is Yes. Updating this column's values after a feature has 20 measurements may cause its SPC values (e.g., Static CPK and Real CPK) to be updated. |
| Tolerance Type |
This selection affects the format of the feature's specification, and which of the following fields is available:
|
| GDT Callout | Geometric dimensioning and tolerancing callout frame. |
| Units | Unit of measurement used by the feature. |
| Bubble Number | If Bubble Number is used, then it is displayed on the measurement entry screen instead of the feature number. |
| Group | Name of a group of features. Used as a reference in quality reporting and eTags. |
| Tool Types | Category of tool used to measure feature |
| Part Revision | Part Revisions applicable to the feature. When a Revision is selected on the Record Measurements page, only the features aligned with that Part Revision are made available for measurement. |
| Processes | Tooling or methods used to create feature. Can be configured under Settings > Company Setup > Quality Management Setup > Processes. |
| Dimension Type | Type of feature |
| CpK Metric Basis |
CpK calculation method, choose between: Note: If "Min(CpL, CpU)" is selected for a feature with a one-sided tolerance, then the selection will be ignored, and CpK will be calculated based on CpU or CpL instead. |
| Reference Location | Location of feature balloon number on the drawing |
| Characteristic Designator | Type of characteristic (e.g., critical, key, flight safety) |
| Designator | Optional secondary designator field |
| Setup Comments | Optional secondary reference location field |
