Thread Milling

[Mark Summe]

Any one have any tips/ tricks for thread milling?

I threadmill all the time. No real trick to it just make sure your settings are correct.

 

Are you having problems with this feature?

 

BTW,

Climb cut (RH - start from bottom on internal threads, top for external threads)

There are many threads listing parameters, speeds and feeds. ToolFab, is probably the expert around here since he manufactures thread mills.

It may not seem like it when you select geometry but the size of the hole makes a difference in the toolpath. Depending on your tool, you may need to fudge the "number of active teeth" at the top to make only one pass. Sometimes the tool will make one pass at the bottom and then move up to make another pass to cover the full depth of the hole if your hole depth needs more threads than your parameter number. I make several passes in different ops and add to the "allowance(overcut)" option to finish holes that need to be fit to a guage. Make your hole slightly smaller than the finish size (.735 hole for 3/4 threads) until you know how your tool is going to cut, then increase the overcut until you get the desired size.
