Thread Milling Wizard
« on: June 03, 2007, 02:14:58 PM »
Want to do some thread milling with a single tooth cutter.  When I use the wizard on field is Major/Minor and I am not sure what to put into this as a value the major or minor dimension?

I have not used it or even looked at it but could it not be meaning if you are doing an external thread you will put in the major and if doing an internal the minor?

Thanks for your input... I'll give it a try and see how it goes.

Thanks again.

It might be me but that website description makes very little sense to me.  Just look at the relationship between H1 and h3. 

I also tried to calculate to the outer point (above D) and that made no sense either. 

If you use a thread pitch of .75mm then the long side of the 30 degree triangle is .65024 mm again that does not correlate with H1 or h3 or even (D-d3)/2 which should be very close.

I am not sure this diagram is correct at all.

Well I got it to work with some help from Brian :).  I wanted to match some existing parts that I had.  They are 10 x .75 mm threads.

I used this cutter on the mill.

Here are the test parts made from wood.







Now to try some real pieces.

Thanks for all the help!  ;D ;D
