Picture Frame/Part & Tabbing Example


A key concept in using Invert-A-Bolt™ fasteners & related products is the idea of tabbing parts. Whether it is a nesting application (to reduce setup time & cycle time) or for individual parts, it is important to know/understand/apply the concepts of tabbing. Please refer to the pictures in which over-the-top, foil, and mid-flange type tabbing is shown/described. For even more understanding, download the provided 3D CAD *.STEP file in which these features are modeled.

Call us if you have questions! But, please note a couple of things:

  • The model only shows the finished condition of the part. It does not show the interim material situation as the part is machined.
  • The over-the-top and foil type tabs are only revealed in the FINAL OPERATION of machining the part. This is the beauty of using this concept~ the part is very stable until the final operation, when the tabs are formed.
  • The IVB Universal Common Modular Fixture (UCMF) is often used for nesting parts, but requires the use of the tabbing concept to accomplish the benefits of that process.



    We also have videos that also provide insight into picture frame/ tabbing of parts.
