Bar & Tube Fabrication Node Options

The Bar & Tube Fabrication node provides the following setup options:

• Punching Strategy for Generic Extrusions

Enable Scrap Material Credit

By default in starting point VPEs, the cost model assumes that material scrap (for example, trim scrap) is not sold for credit. Administrators can customize the default with the cost model variable enableScrapMaterialCredit (false in starting point VPEs). With this setup option, users can override the default on a per-part basis.

Enabling scrap material credit increases material utilization and decreases material cost. The credit rate is specified as a percentage of the material rate by the material property Scrap Cost Percent. See Material Cost and Utilization.

Enable Scrap Part Credit

By default in starting point VPEs, the cost model assumes that the material from scrapped parts is not sold for credit. Administrators can customize the default with the cost model variable enableScrapPartCredit (false in starting point VPEs). With this setup option, users can override the default on a per-part basis.

Enabling scrap part credit increases material utilization and decreases material cost. This includes credit for parts scrapped by this process as well as by downstream processes. The credit rate is specified as a percentage of the material rate by the material property Scrap Cost Percent. See Material Cost and Utilization.

Punching Strategy for Generic Extrusions

By default, all a part’s holes and cutouts are machined on a router (rather than punched), if any of the part’s holes or cutouts lie on a fully-hollow CrossSectionHollow GCD. Users can override the default on a per-part basis with this setup option. The following options are provided:

• Option 1 (default): all a part’s holes and cutouts are machined on a router (rather than punched), if any of the part’s holes or cutouts lie on a fully-hollow CrossSectionHollow GCD.

• Option 2: all a part’s holes and cutouts are machined on a router (rather than punched), if any of the part’s holes or cutouts lie on a fully-hollow or semi-hollow CrossSectionHollow GCD.

• Option 3: some holes or cutouts may be machined while others are punched.

• Option 4: all a part’s holes and cutouts are machined on a router, regardless of whether any holes or cutouts lie on a CrossSectionHollow GCD.
