MillBlunt - Machine Bluntstart and Quickstart threads with live tooling in GibbsCAM.

MillBlunt are a stand-alone plugin and allows you to very quickly generate geometry for milling away any incomplete threads after threading.

This is accomplished using live tooling on a lathe.

MillBlunt generates helixes in all the main coordinate systems on a lathe with live tooling. Tested and used in-house for over 3 years, method is applied to hundreds of threads.
Its basicly a fast and easy helix geometry generator. It also offers as an alternative to the built in Helix Builder in GibbsCAM.

  • Autodetects GibbsCAM environment (Inch/Metric)
  • Geometry can be segmented to force post-processor to output G1 moves, which can be advantageous on older machine controllers.
  • Two shapes for how to mill the blunt start, out in a sloped line or with an arc ( in YZ plane with Polar & Cylindrical Milling )
  • Supports geometry for righthand / lefthand and both ends of an external and internal threads in YZ Plane and XY Plane.
  • Keeps all geometry in a seperate WG with description, any change with a redo in plugin will update the WG description.
  • Active logging, last values used are saved and loaded back the next time its started.
  • Option to store all data inside the GibbsCAM file, for loading back and edit/redo.
  • Online documentation accessible directly from the plugin.
  • A great free tool to have in your arsenal.

    MillBlunt can also generate all kinds of parametric helix geometry to be machined with live tooling, see the PDF documentation for more examples.
