Jon, you do all op in one shot! It mills the hole and cuts the thread in a helical motion with feed rate to suite material. Works very well as intended in recommended materials, done some threading in steel but in pre-drilled holes with this tool. /Bengt Den 2017-02-04 kl. 03:57, skrev Jon

Re: [Emc-users] Does anybody know about this interpolated tapping ?

Several times I have milled threads (both internal and external) with a lathe ID threading tool. Instead of a single row this would be called a single tooth thread mill. Put it in an end mill adapter and voila you have a thread mill. You can mill whatever pitch you can program and whatever

Re: [Emc-users] Does anybody know about this interpolated tapping ?

With this interpolated motion there is no need for spindle reversal when tapping it is also faster as the tool can move out from the hole rapidly On Fri, 2017-02-03 at 18:06 +0700, TJoseph Powderly wrote: > i've not done it with linuxcnc > we did it a lot in heidenhain tnc controls for sink

Re: [Emc-users] Does anybody know about this interpolated tapping ?

i've not done it with linuxcnc we did it a lot in heidenhain tnc controls for sink edm google thread milling you need a tool with the correct pitch on smaller shank than the drilled hole how the metal is attacked can be: goto to the bottom before interpolating an expanding circle or helix
