Thread Milling Made Easy

Thread Milling Made Easy with Fusion 360 In this video I show you how i set up my Thread mill in Fusion 360 to generate the G code. I get a lot of questions on thread milling Hopefully this helps. Please feel free to ask questions and leave comments

Great video, thanks very much👍 Just about to use a single point thread mill for the first time on my mill, and your walk through Fusion360 was just what I needed. Many thanks

[@CNC4XR7]

Glad it helped

[@stevetriton1060]

Thanks for sharing Sam. You just reminded me I need to go in to FUSION to create a TTS holder and ER holder.

[@CNC4XR7]

That used to be a very simple task when fusion first hit the scene not so easy now. Tormach should have a ttsgolder model in fusion.

[@Ale_Lab]

In your tool library you just need to pres add new tool, select holder and design it. You just have to add segments to make the holder. Takes 5 minutes.

[@Vytor01]

Thanks for answering my question by making a video!

[@CNC4XR7]

Your welcome ! There's about a dozen of you who were curious. I hope I answered all the questions.

[@RJMachine62]

I do enjoy watching your video's so keep them coming!

[@CNC4XR7]

Thanks Glad you enjoy them.

Liked/Subscribed/Notified. Great videos, Sam. Keep up the good work. I'm just getting the hang of Fusion360 Manufacture mode... Modeling with F360 is pretty easy. I've also been using Mach3 for a long time. Thanks again. Please keep posting the great videos.

[@CNC4XR7]

Thanks Joe!

[@rc-cnc3431]

Awesome job Sam. Very informative. Sure beats compression tapping :)

[@CNC4XR7]

Your not kidding!

[@qzwqsy]

Thank you for the great video!

[@CNC4XR7]

My pleasure!

[@MrDante195]

Thank you very much, i have successfully tapped my first hole using this tutorial

[@CNC4XR7]

Happy to help

Glad you liked it!

[@Chris6000]

Nice video as always. I have not tested to thread in my mill yet but maybe I will try it now. Which program do you use to record the screen for the fusionpart?

[@CNC4XR7]

Roxio screen recorder it works but not that great.

[@plnmech]

Your original PM mill does such a good job do you think the money and effort that you put into to the new Pm mill will be noticeably better?

[@CNC4XR7]

Yes the Original is doing a very good job in its current form. The linear rail machine should be noticeably better due to less machine flex and more rigidity. Will it be worth it? I think so time will tell.

[@RJMachine62]

At 13:03 you say you can adjust your thread pitch to make a tighter hole? Thread pitch should stay constant, especially when defining a tool, but pitch diameter could be adjusted in the CAM portion right?

[@CNC4XR7]

Unfortunately the thoughts in my mind do not always make it out of my mouth correctly. You can adjust the Pitch Diameter offset That is what Fusion 360 calls it. Normally this is the same as the Thread pitch.

[@RJMachine62]

@@CNC4XR7 Well, trying not to argue but if you put these video's online for people to also learn then the terminology needs to be somewhat correct. Thread Pitch is the distance between two threads and it derived from 1 divided by the number of threads per inch. Thread Pitch Diameter is the imaginary line between the peak and the valley of the thread which is used for the standard of measuring threads. You can adjust the Pitch Diameter Offset in the CAM portion of Fusion in order to compensate for the tip of the tool and other variables, which in essence modifies the Pitch Diameter. If you adjust the thread pitch, then you're making the threads closer or further apart which has nothing to do with diameter. I'm almost certain you already know all this and you simply crossed your thoughts as we all do, but we don't want others trying to adjust the thread pitch to make their fit tighter or looser. :)

[@SteveInFLALand1]

Great video. I'm trying to save this video but there is no "save" button. Do you know why?

[@CNC4XR7]

I'm not sure but it should be in your watch history

[@MamunurRashid-il4rj]

Can I run a lathe threading tool for a thread mill operation in milling.

[@CNC4XR7]

I'm not sure I guess it depends on what the tool looks like.

[@trialnterror]

If I sketch a 1/2 13 hole how would I sketch it to a minor dia? What do you mean by that

[@CNC4XR7]

There are a couple ways to model the holes. If you sketch the holes just draw them to the minor diameter vs the major .5

[@petermorphett]

Nice, but here is one for you, how do you cut a 1/4x20 UNC thread with a 1mm pitch single tooth cutter in Fusion (4.8mm Dia like in your video) ?

[@CNC4XR7]

the procedure is the same just change all the tool setting to match your tool.

[@trialnterror]

In a video from nycnc they didn’t model the threads they just made the hole and selected the hole to thread it.

[@CNC4XR7]

Yes You are correct that is a feature that was added to fusion about 2 years ago I think. very useful. If you design with sketches just remember to draw the holes at the minor diameter. later in the design when you thread the holes fusion will model then correctly. I have ran into issue where I had tried to thread mill a hole and every time the threads were to loose. when i went back to check the Sketch and model the hole was drawn to a larger size. Fusion was just following the tool path.

[@ReiniGrauer]

Threadmilling made even easier: On your modeled threads, choose the major diameter. Then you don't need to work out the Pitch Diameter Offset at all. The end of the cutter will just hit the outside of the thread form. For a single form threadmill, you can offset the face a little bit outwards to compensate for the sharp point at the cutting edge of the tool. Doing threads like this almost always nails the hole on the first try without having to do any math or guesstimating.

[@CNC4XR7]

Great Tip! Thank you!
