The EPDM (Enterprise Product Data Management) is a special data management system that we use for managing CAD files. The EPDM controls who can work on a file, so only one person can make changes to a file at a time. In order to provide this control, if you want to edit a file, you must be connected to the EPDM server and check out the file. Before anyone else can work on the file, you must check the file back in, which ensures your changes are saved to the server before anyone makes more changes. When you create a file, fill out the properties box so we can keep track of necessary part information. Here’s an example:
We will be using a part numbering system for flight hardware, in the form XX-YY-###. The first two letters are the subteam designation, the second two letters are the subsection designation, and the last three numbers are the part ID, which will be assigned to custom fabricated parts in increasing order. Common COTS parts can be stored in a separate folder under their part numbers. -000 is the subsection assembly, so part numbering starts at 1. Ground support equipment and other projects that will not be flying on the rocket can use naming standards as determined by the subteam leads directing these projects.
Subteam designations:
| Subsection designations:
|
|---|
For example, the fin can assembly would be AS-FC-000. The fin can tube will be ST-FC-001.
When you check in a file, it will ask you to fill out comments. Write a quick sentence explaining what changes you made so we can keep track of part versions.
