The following is a summary of how the Multifeeder Technology part numbering system is intended to be used, and how to keep track of revision control for all parts and procedures.

 

Parts and Procedures

All part numbers that are not for “Procedures” have five digits followed by a two-digit revision level suffix.  Assembly Procedures have a leading “1” in front of the five digit part number of the assembly it is an assembly procedure for.  Test Procedures have a leading “2” in front of the five digit part number of the part/assembly it is a test procedure for.  Other items of documentation have other leading digits.

Example:

If we have a mechanical sub-assembly numbered 43235-00, then assembly procedure for this sub-assembly would be numbered 143235-00 and the test procedure would be numbered 243235-00.

 

“Group Number”

The first digit in the five digit number indicates which group that part/assembly belongs to;

1    Drive Components 5 & 6    Electronic Components
2    Enclosure & Mounting Components 7    Electronic Sub Assemblies
3    Mechanical Assembly Hardware 8    Electro Mechanical Sub Assemblies
4    Mechanical Sub Assemblies 9    Finish Machines

 

The “Assigned Part Number”

The “Part Number System Table of Ranges” spreadsheet further specifies what ranges of part numbers are to be used for what parts.

 

The “Revision Level”

The last two digits after the dash line are reserved for revision levels of that particular part number.  A part increases in revision number when a modification is made to the part and the part is still backwards compatible.  If a modification is made to a part and it is not backwards compatible, a new part number should be issued for the new part.  The standard procedure for assigning revision levels is to alphabetically increment the last digit for every revision.

 

Example:

If a modification is made to the part with part number 43235-00 such that the part is backwards compatible, then the revision level of the part should be incremented to –0A, giving the final part the part number 43235-0A.  After the 27th revision to this part it would have part number 43235-A0 and after the 54th revision to this part it would have part number 43235-B0.
