Is is not that hard use the Threadmilling Toolpath. Keep the surface speed like a normal tool and use a decent chip load. I personally like full flute type cutters for cutting threads verses single point type. You also need to make sure the machine supports helix toolpaths.

I am looking for a threadmill library for Mastercam x5. Please let me know if there is one available.

[Mr. Wizzard]

They don't take long to make. I usually use Carmex threadmills. You can order one and all you need is the tread mill ( to measure step diameter), the Carmex page, and some thread data from the Machinery Handbook. You can make one in, probably 20-30 minutes the first time. After you get used to it, it goes pretty quick.

Just make sure you have the tool defined correctly and pointing to the right file, so your geometry is correct. If you take the time to do it right, it will pay-off with accurate backplot and verify toolpaths.

[Mr. Wizzard]

Here's a sample thread mill toolpath with a Carmex 1/4-20 thread mill. Part # is MTS0250C55 20 UN and the geo for the custom tool is on level 10. Anybody is welcome to it.

To anyone who downloaded my thread_mill_sample, please let me know if it worked out. I don't upload many files and I would like to know if I did it right and you were able to open it.

Thanks.

+1000 for Carmex

 

I have had excellent results with them cutting a wide variety of materials to some rediculous depths.

There isn't one that I know of. Carmex has a great online catalog and utility that gives you all the specs for thier tools. Just use a flat endmill with the diameter of your threadmill. If you are worried about the way it "looks" in backplot or verify, you can make a special tool. I haven't bothered taking the time yet to do it myself.

 

What kind of material are you wanting to threadmill?

[crazy^millman]

This is something that has been asked for many times. I did share a tool libary on the ftp that had a bunch in it. I am in the air over somewhere. I will try to make a zip file of just threadmills and put it on the ftp.

[Mr. Wizzard]

Again, if anybody tries mine and it works, please let me know. I could put up some more Carmex ones, but won't waste my time if it is of no use. I would just like some feedback to let me know if I posted it correctly and someone was able to use it.

thanks.
