Utilizing system and custom properties for part number and other metadata type information in solidworks allows automated BOM's, drawing title blocks, notes, etc. Keep in mind that for all our numbering schemes the filename of the drawing and the model matched the drawing number. No spot for revision level. When I start a part numbering system … Dash numbers are normally used to indicate different variants of a part… 402. Engineers often view part numbers as a bureaucratic process forced on them by the sales department of the company but they can have far-reaching efficiency and legal complications. Electrical drawings on project number plus E, gas drawings on project number … that the same part can be used in different projects without any friction. 1) Drawing and Part numbers need to be separate numbers, generally in the past I would make the drawing for a part or assembly ABC123 and the parts belonging to that drawing ABC123-XX-YYYY right now the drawings are AB123456 and the part or parts in that drawing are the same number … Use a sequential alpha-numbering system The part number only needs to be unique. It is worth looking at optimizing or revisiting part numbers at the start of the manufacturing process.  As the number of self-similar parts grows, a company relying on descriptive names realizes that the names are becoming the long flowing titles of many a cheap Victorian novel – duplication ensues.  Assigning a controller would seem to be needed, but often in companies at this size the desire to hire a person for just this specific task is weak.  The result is the creation of an “intelligent” part number system.  A set of rules that anyone in the company can follow to generate a unique part number. The part number does not provide any information about the part. These systems often have problems with change, especially when there is a change to a part after the initial design has shipped to customers.    Eventually, any “intelligent” part numbering system encounters a need its designers did not anticipate.  This is the primary reason we advocate the next sequential number system.  (Sometimes referred to as sequential random numbers. If you have your serial number parts lookup is even easier , use the serial number … The first two letters, the discipline designators, identify the construction discipline that the sheet covers - architectural sheets, plumbing sheets, structural sheets, etc. A part … They are numbered from the bottom of the parts … Our proprietary software will cross reference between NATO Part Numbers and US NSN Part Numbers where applicable. )  In this system, whenever a part number is required, a service supplies the next number. … A part number (often abbreviated PN, P/N, part no., or part #) is an identifier of a particular part design used in a particular industry. The only way to build such a context is to architect a recognizable system, and one that lasts. Intelligent Numbering: What’s the Great Part Number Debate? The first nine digits of the part number reflect the drawing reference. Drawing identification 37 404. Part or identifying number 37 405. More teams are using Cloud, Analytics, Mobile, and Social tools to speed up product development. Independent analyst firm, Consilia Vektor, explains how this changes Product Data Management (PDM) as you know it and how this can help your team work smarter. Both approaches are myopic because they are extremes that wholly ignore the other’s chief advantage. that anyone can easily search for and find a desired part, it to handle any logistical situation without choking, and. CIN, on the other hand, upholds a humanistic appreciation of history. Designed by CastleCS - Marketing & Advertising. The part number is simply something that fits in the little boxes on drawings. 1. Just keep that story foremost in mind when you design your company’s part numbering system. resistance to files being compromised by poor discipline. Activity Drawings.” Parts made to these drawings typically would be manufactured through the Fabrication Engineering Branch, Engineering Services Division, GSFC. Does your system: If you want your system to thrive under any amount of growth, you will want: Sounds like a fantasy? Part numbers … Its purpose is to simplify reference to that part. When the part is revised and the part number changes it will be easier to do a save as with the drawing … … Part numbers are merely unique markers that point to a collection of metadata, and people shouldn’t bother with them. Tie the part number to the principal drawing file name and not the part file or configuration. Allow for part numbering, file naming and part description automation? Using the same part number for two entirely different parts can cause serious problems including delays on the manufacturing line, confusion over the BOM record, and ordering of incorrect parts. First, some useful definitions of words that we’ll be using in this DFM Tip: Manufacturer Part Number (MPN)– The unique part number that the manufacturer assigns to a specific component with particular specifications in its catalogue. Let’s understand why. I plan to number drawings and parts with unique references. For reasons similar to those described in our part numbering system designtopic, a drawing or document number should be: 1. as short as possible, commonly no more than 7 characters; 2. purely numeric starting with 1-9 (never 0), without any letters or symbols (if symbols are necessary, then limit to the characters available on the computer keyboard's number keypad, typically "-"); and 3. without any significance or value attached to any of the characters, and unr… ​ Sequential Part Number System: Here’s what we suggest for a company to use on their cad/part numbering system that will provide minimum friction and maximum flexibility. Take advantage of our experience working with many companies in all sorts of industries and ponder the following topics: ​ Part numbers, once created, endure. If the company is successful then fifty years after the manufacture of the components and the publishing of the parts list a junior employee will get a phone call and will be expected to provide a replacement based on the information identified by the part number. “Contractor Design Activity Drawings”””” (which are a company's drawings bearing the company name, address, federal code identification, and drawing number… Just ask Ray DeGiorgio, the GM engineer who infamously approved a change to a higher torque switch without changing the part number. They're happy with the system. Intelligent Part Number Systems: Often companies like to have a system with an inbuilt code that can be used to determine the part number of an unknown part if the descriptive information and the format is known.  They were especially common in the pre-computer days but have no real place in the modern production systems.  These “intelligent” part number systems tend to cause pain that outweighs any of the perceived benefits but they seem to take on a life of their own and cannot be easily killed. If you are dissatisfied with your current system or having troubles preparing files for a PDM vault implementation then we have tools to help, just call 604-986-9696 and ask for Marc. Bourns Inc. CRT0805-DY-1R00ELF. The next sequential number system is easy to implement, simple to automate and ‘soldier-proof’. As you can see from the example above, a number begins with the project number (17002) and is then followed by a 3-digit number … The Computer-Aided Design ("CAD") files and all associated content posted to this website are created, uploaded, managed and owned by third party users.

There’s no shortage of arguments about one approach over the other. Free 3D printing software to simplify your Stratasys 3D printing workflow. Looking back, traditional part numbering systems and document identification methods originated well over five decades ago. 22.
