Depending on your company’s culture around “make/buy” decisions, you might find your bills of materials extremely complex and cumbersome. If they are equivalent, should they be assigned the same part number, and visibility of the original difference lost? If the answer to the previous question is “no”, then should the difference be carried through to the finished assembly, making it a different finished product? Are costs the same? These are interesting business discussions for your ERP project team.ģ. Regardless of the reason, be prepared for passionate discussion about the extent to which these are truly “substitutable”. You might have two equivalents because of capacity limitations in the supply chain you also might want to keep two suppliers to ensure competitive pricing. You may find that a raw material, component or subassembly is known to have two or more “substitutable” equivalents that are informally managed.

Because of this, it may feel more organized to build BOMS from the bottom up, rather than the top down.Ģ. You may have ten raw materials that are crafted into one hundred component parts that are combined into one thousand different subassemblies that create ten thousand different variations of finished product. There is typically a funnel shaped explosion of complexity as you move upwards in the bill of material structure from raw material to finished product. An automobile cannot be sold with only three tires, or lacking an exhaust pipe.īelow are some examples of BOM issues you may find interesting when designing your ERP blueprint:ġ. Always remember that in discrete manufacturing, if the bill of material is not 100% complete and accurate, the product will not get made. You are welcome to contact us If any questions about CNC machining threads.For those not familiar with managing multilevel bills of materials, be prepared for some surprises as you build your BOM structures into an ERP implementation.

To select the suitable thread cutting tool does matter for different kinds of raw material or thread dimensions.

General Note: All dimensions are in millimeters.Īn internal thread is usually manufactured by a thread tap or a thread cutter, depend on the size of the thread. Our CNC machining services could provide you the parts with precise manufactured thread which is inspected with thread gauge to ensure the quality. Threads can take an important role for assembly, mating and functional adjustment. Metric threads, no matter the external one or inner one, are widely used on the CNC machined parts.
