Thank you
I got it to work by drawing geometry of a helix at a major dia of 9.205 with a pitch of 1.25mm. I then drew up the form cutter off of the drawing and linking it into mastercam by a "level". I used "curve" multiaxis toolpath. See image below for cut pattern but to sum it up curve type is the helix and radial offset is the tools radius (at smallest dia at 5° angle). For Tool Axis control see image below as well. The tool is set to rotate around the "Z" axis. Side tilt angle was set to 5.0 for the 5.0 degrees that cut into the tool. Lead/lag angle is set to -2.7743 because of the compound angle to allow for the tool to cut proper.
Best of luck!

I can give you a x.t file of the thread but not the whole part. m9x1.25 minor 7.72mm major 9.205.X_T

JParis,
Would you be able to put more emphasis on a "rolled" toolpath?

Working on getting a pool of information around for being able to do a Buttress Thread in a 5th Axis mill using Mastercam 2020. I know it can be done but I personally haven't done it yet. I am hoping to educate myself on the matter so I know my constraints and limits when setting up the toolpath. I have listed the thread and tool called out that would be used. I know the toolpath used cutter comp to control the size of the major diameter of this particular thread. This leads me to believe that the toolpath used was "Curve". I believe the toolpath has to be derived from a helix spiral geometry. Could anyone bring light to this toolpath?

Crazy Millman,
I am sympathetic to your remark about "not having what you needed". This is the very first post I have done on the Mastercam forum. I learned you can't use drag and drop when inserting a image into the text area. You must choose file then insert the file into the text area. I did not know at the time that my images did not get attached. Until you pointed out that there was no image of the form cutter. If you don't reach out to your customer asking if they have a specific tool then they might figure that is on you to come up with the tool to use.
