New thread feature question
SOLIDWORKS Forums
8 days ago

Hi all,

     I'm quite new to Solidworks so please forgive my ignorance.

 

Most of you have probably played with the new Thread feature in 2016/2017. My question is, is there a feature or option to run the thread out rather than have it finish at a sharp 90° as shown in the below photo?

 

For example, if this bolt was being machined in a CNC lathe, the CNC controller will know to slowly "ramp" or "runout" the threading tool so it doesn't come to a sudden stop like pictured.

 

Can this "feature" be illustrated in my Solidworks model? Thank you!

Attach your file here and I will demonstrate how to include the runout.

One way is to add a sketch to that face and convert the face entities into sketch lines and do a Cut Extrude "Through All"

I don't know anything about machining threads, but is this what you want?  I used the method recommended by John Stoltzfus.

 

(By the way, I didn't use quite the same workflow he described.  I selected the face, then selected the "Extruded Cut" tool.  That opened a sketch on the face, and the face was still highlighted, so I selected the sketch tool "Convert Entities", which placed sketch lines around the perimeter of the face.  Then I closed the sketch and was immediately taken to the "Extruded Cut" Property Manager since I had pre-selected it earlier.)

This is the way it looks when I cut it on the lathe.

  But do not use to many in an assembly, cause they will sure slow the machine down.

This is the method used in many YouTube tutorials. I couldn't see any YouTube tutorial with J.M. method.
