The unique section of the part-number would be derived from a master drawing list controlled by the design office. Whether you use an intelligent or non-intelligent part numbering system, it is important to make sure you do not duplicate part numbers. Just ask Ray DeGiorgio, the GM engineer who infamously approved a change to a higher torque switch without changing the part number. Design gaps in numbering to permit grouping some numbers together when it makes sense to do so. You probably have stories to tell, then. Its purpose is to simplify reference to that part. Sequential part numbers… You have a two part identification system where the first few numbers identify important variables separated by a dash then an individual product ID number… | Designed by CastleCS - Marketing & Advertising.

Power Failure: An argument for the “intelligent” systems is that in the advent of a power failure it is possible to determine what the part is without using a computer.  Power failures have become rare events and as a general rule our dependence on electricity so great that most businesses would close early if the power does not return quickly.  For these rare cases, the solution is to tie the part number to the main drawing number. CIN, on the other hand, upholds a humanistic appreciation of history. But it’s much more than just crafting a semi-intelligent system and calling it a day. The part number is simply something that fits in the little boxes on drawings. Allow for part numbering, file naming and part description automation? It is completely worthless for anything else, because the attributes to the part number can store far more information than a part number … Part numbers: so simple, what could possibly go wrong? To get the greatest combination of files with some added comfort, use something like this. 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. Part numbers are important; they will always be the subject of conversation, collaboration, and argument between humans and not systems. 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. Find genuine factory OEM Mercury Marine, Mercruiser and Mercury Racing parts for your engine, sterndrive or a Mercury accessory using detailed drawings and images. Our proprietary software will cross reference between NATO Part Numbers and US NSN Part Numbers where applicable. 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. Let the numbers evolve as the design matures, and solidify those numbers into something that is meaningful through a release process. The GNC was founded on the philosophy that part numbers are inconsequential. Let the machines do the work, keep humans and their fat-fingering ways out of the loop. little to no training needed to generate new part numbers. Construct them with just enough information and structure for readability, keeping digits in groups of 5 or less. PDXpert PLM software has been designed to support a wide variety of part numbering systems, including manually-assigned intelligent part numbers, category-based semi-significant part numbers, and easy-to-manage sequential part numbers. They're happy with the system. Easily distinguish between similar parts with similar descriptions? You’ve heard of the Apollo 13 mission where a single un-insulated wire resulted in exploding oxygen bottles, an aborted moon landing and the astronauts barely making it back with their lives. These part numbers are based on the engineering drawing that defines that part and assembly. Part numbers … 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.

The third digit, the sheet type, is a number that represents the type of drawings that are on the sheet - plans, sections, details, schedules, etc. Looking back, traditional part numbering systems and document identification methods originated well over five decades ago. The next sequential number system is easy to implement, simple to automate and ‘soldier-proof’. Keep in mind that for all our numbering schemes the filename of the drawing and the model matched the drawing number. ... You can create a property for anything you want to control in a part, assembly or drawing. Parts List or BOM (Bill of Materials) In the assembly drawing above notice the arrangement of the numbering of the individual sub assemblies, components and standard hardware. The organizational system has its root in manual paper-based record keeping, and involved the use of document identifiers and descriptive part numbers that give an idea of what the item is. They would review the drawing and send it to the appropriate manufacturing department or supplier to procure a quote resulting in an order for a number of parts. Bourns Inc. CRT0805-DY-1R00ELF.

Way too easy to overlook! After all, even the most elaborately designed intelligent part-numbering system is a temporary triumph, which will succumb to degradation, confusion, and irrelevancy over time. And to facilitate those interactions, part numbers must provide some system-independent context in of themselves because there comes a time we have to look up from our screens and communicate one on one. The process is done automatically during detailing, so once the drawings are created, the part marks are updated to match the new drawing numbers. No spot for revision level. Both approaches are myopic because they are extremes that wholly ignore the other’s chief advantage. Part numbers are the inevitable result of any manufacturing company.  Too often laced with their profusion of spaces, dashes, slashes and sub-codes, they are designed to trip up the unwary.  They serve a useful function of separating variations on parts and mean to ensure that the correct part out of many with a similar description is the one that is ordered.  Their primary purpose is to remove ambiguity. Using this part numbering system, a resistor could be assigned part number 000416782. The number format would be 'Category 1, Category 2, Category 3 - XXXX' (where is X is a cumulative number). Let’s understand why. Perhaps you're a strong proponent of one side of the debate or the other. Each drawing number can then … that the same part can be used in different projects without any friction. As a System Architect here at Javelin Technologies, there have been many discussions with SOLIDWORKS users about using Smart part numbers versus sequential part numbers.. Smart part numbers contain descriptive and informative details that provide relevant information about the part, such as Commodity Code, options, colour and finish, etc. 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.
