ThreadTracer 4 - Online Guide

ThreadTracer uses a tabbed interface to present its parameters to you. Whatever thread is selected will have the appropriate thread data displayed on the first tab.
Switching between the different thread types are found in the Control tab. You will find descriptions for all input boxes and options in these pages.
Click the 'Online Guide' button in the plugin and it will open this online documentation in your web browser.

Freeform Thread \\ Thread Data Tab (Tab 1):

  • Major Diameter : Enter the Major diameter for the thread.
  • Minor Diameter : Enter the Minor diameter for the thread.
  • Thread Height : Enter thread height.
  • Flat Root Width : Enter the flat root width.
  • No. Starts : Select number of starts, if the thread is multistart.
  • Lefthand Thread : Check this if its a lefthand thread.
  • Ext / Int : If the thread are external or internal.

  • Under the Padlock symbol are 3 checkboxes to lock diameters, if the two upper boxes are checked, the thread height will always be calculated from the two locked numbers.
    Locking Major Diameter and Thread Height, the Minor Diameter will be calculated with using the locked numbers.
    Only 2 numbers can be locked, if all three are locked, it will by default always use Major and Minor diameter and then calculate thread height.

    TPI and Pitch

  • TPI of the thread. Select to use TPI or pitch with the radio button.
  • Pitch : Pitch of the thread.

  • Thread Form

    Select thread type / form using the radiobuttons.

  • SQUARE - Square thread with straight vertikal flanks (0° angle)
  • TRIANGULAR - V-Shape threads, like UNC/UNF threads, Metric ISO threads, API etc.
  • TRAPEZOIDAL - Acme, Stub Acme, Custom buttress, Ratchet threads.
  • ROUND - Rope threads, Cable Drum grooves and overall rounded thread forms.

  • Make sure to choose correct type as ThreadTracer uses different calculations for different thread forms. For example Triangular and Round forms have no Flat Root Width.

    On Freeform Threads, you can set the parameters on all features and create highly customized thread forms


    Set the angles for right and left flank with the two input boxes to the right, angles are measured as 0° are straight down.



    Control buttons at the bottom.

    Use the buttons at the bottom of the ThreadTracer dialog to turn on or off actions to make.


    Everything in the window is controlled by the 'Do It' button.

    You can turn on/off options, generate visual geometry, change cut depths, change tool sizes and everything will be recalculated and updated when you press 'Do It'.
    As long as the 'Process Ops' or 'NC Postprocessor' are disabled, no GibbsCAM operations or g-code will be generated.

    Set up the all the roughing and finishing of the thread and only enable 'Process Ops' when everything seems correct. With 'Process Ops' enabled it will generate GibbsCAM threading operations.

  • Material Control : This will enable material control, and keep all threading cuts within the set limits. By default the limits are always set to Major and Minor diameter.
  • Do Roughing : This will enable roughing of the thread. When enabled it will run the roughing of the selected thread with the set tool parameters.
  • Do Finishing : This will enable finishing of the thread. When enabled it will run the finishing of the selected thread with the set parameters.
  • Process Ops : This will create GibbsCAM threading operations for all the calculated thread coordinates.

  • 'Do Roughing' and 'Do Finishing' can be set individually. If only 'Do Finishing' is enabled and 'Process Ops', it will only create GibbsCAM threading operations for the finishing passes.

    Click 'Do It' button to start running the options that's selected.

    Click 'Save Data' to store the current thread setup into the GibbsCAM program

    It will create a new data entry if its a new thread, after the thread setup is stored the button will change to 'Update Data'.
    This way you can store and update the same thread entry, and not create a completely new thread entry every time the 'Save Data' is clicked.
    If you need to create a new data entry in the GibbsCAM part, you must close ThreadTracer and restart it, and it will now start with a new data entry.


    These lines of text can also be copied and pasted into other GibbsCAM programs, to quickly recreate the thread without typing in all the parameters again.
