Numbers, not letters Computer keypad characters are most efficient for high-volume users. This is then further defined with the unique top level assembly number 456. Just index the number every time you need a new one. Everyone starts by envisioning how convenient it would be to tell, at a glance, the important characteristics of a part, or the document number that describes the part. We experimented with many smart part numbering schemes.
Do not create groups that have no distinguishing business rules, or that require any thought about whether a part belongs to one category or another. The software easily accepts mixed schemes, such as importing legacy significant numbers while auto-assigning shorter non-significant numbers. Mather: Bills of Materials, page 100 I prefer a non-significant number because there is a longer life and less error. The only problem with this is that it's probably the most expensive route up front. Obviously, the greater the number of digits in a part number, the greater chance of error.
Let me know if you need anymore information and I will do my best. Perhaps you're a strong proponent of one side of the debate or the other. Focus on requirements, not history A part fulfills a function, and has characteristics deemed critical to that function. We tend to oversell the utility of mobile tablets, phones, etc. The software easily accepts mixed schemes, such as importing legacy significant numbers while auto-assigning shorter non-significant numbers. It's worthwhile investing the time to validate your design.
Even with nearly a million parts to contend with, one can see the benefits in compression here — only six digits are required to uniquely identify any part in the database. One of the main detractors in a startup situation is the resistance to updates. However, never encode trade secrets related to materials, processes and other proprietary knowledge — even where such information reflects essential part characteristics. Part numbers are important; they will always be the subject of conversation, collaboration, and argument between humans and not systems. This is a for a small manufacturing startup.
They no longer do the classification coding function intended by their inventors. Contact us if you'd like to discuss how the general concepts in this note may be applied to your situation. Admittedly, the choice often leads to a contentious debate. Recruit 3 to 5 users in engineering, purchasing, inventory management, production, sales and field service who didn't participate in the scheme's design. The big thing this does is prevents you from having to determine what your design space looks like for the life of the company and generate these huge part numbers that have a ton of extra digits.
The safest delimiter character is a hyphen: 276543-00. Different computer applications may sort varying text lengths unpredictably. Hyphens as delimiters Separate a part number into chunks when it exceeds about 6 characters. These cryptic numbers are often the cause of many human translation errors, as well. Some organizations may require a greater granularity than the manufacturer maintained with their part numbers. Your prefixes could be as simple as Axxxxxx, Sxxxxxx, Pxxxxxx.
Maximum length A practical part numbering system design should account for the limits of short-term memory. For example, don't use -00 for some parts, -000 for others, and omit the dash entirely on yet others. Which of these attributes shall be favored? This allows people within an organization to communicate more effectively with a single index into a shared database. These numbers are often too long and cryptic. To a human, this is usually a two-part index composed of the manufacturer and the manufacturer's part number. Spend the money you saved on Inventor or Solidworks.
Ultimately it requires training new people to look at a reference list and they memorize what the different codes are over time. Unfortunately, there are several disadvantages to this style. And never use a space character. For each description on the list, do all users create the same part number? Our short, numeric, non-significant part number provides the fastest data entry, with the fewest possible errors. Release Number — firmware revision.
Whats your ideal system look like? The keypad allows single-hand operation, and the layout is easily memorized. The question is really what value the additional prefix or grouping provides. Posts that do not follow these rules will be removed on sight. But as with most designs, the part numbering scheme must consider human factors and how the design will be used. As a Senior Manager, Mr. It is only an index into a database and therefore requires access to the database to derive meaning.
