Project 0137 | Making a polygon lathe cutter mechanism

In many cases, a processed piece on the lathe needs to have some shapes in some parts of it not cylindrical shapes that a conventional lathe cannot create. These shapes can be square, hexagons and generally polygons.

I've been in machining my entire life including 5 axis CNC lathe and mill starting out as a manual machinist and I've never heard of or seen anything like this

[@jeremycable51]

I literally just learned about this a week ago when titans of cnc had a short about it seen a different one from them today then five minutes later this video on how to make one pops up on my feed quite amazing tbh

[@sleepib]

I think the secret is that you don't really get flat sides, just an approximation. Even then you'd only get a good approximation at specific combinations of diameter and gear ratio. 19:36 is a good example.

[@user-ig9nt6ps8z]

You sir are absolutly a master with your machine. There is nothing new here just look at all the attachments for the old WWII machines like Monarch,the crown jewel , the cincept is similar to attaching the indexing head to your mill to cut a scroll. Lots of math involved to get the right change gears and all. You know what I mean ,this sort of strategy was common before CNC spoiled us and took away some of our creative thoughts (IMHOP). But what does amaze me Sir is that nobody commented on your skills with the machine. I literally hit the floor watching one of the very few TOOL MAKERS on you tube. Loved the way on your finishing passes the hand champher you did there cant teach that to these youngsters and how you filed the top of the threads lightly and hit them with the file card NICE ! It's those little unnoticed tidbits I observed in your work that go unnoticed that are the difference between a true MASTER of there trade. I Hole heartedly applaud your work it was a pleasure watching some one who knows about the suttle little things that do matter in the end From one Master to another that sir was the most incredible show of skill I have ever witnessed in a video.

Take note This Old Tony … This is how you turn a cube (and many other polygons) on a lathe. By far one of the coolest things I’ve seen done ever, Well done!

[@Skinflaps_Meatslapper]

It's a great concept if all you have available is a lathe. ToT uses either CNC to cut polygons or a dividing head on a mill to get precise flats on more important stuff. These all end up concave on the flats, which would probably be okay for most uses that don't require much torque.

[@MJ-qc1kw]

Is this able to do multiple sizes of each shape by varying the offset or do you need different sized cutting bits?

[@Cara.314]

there's a range that you can do with each cutter, depending how flat you need the flats, larger and smaller sizes with make concave or convex but in many cases is still more than fine for a wrench. you could also have attachments for making internal and external splines. or even a gear hobbing tool, those require more tooling selection for different sizes. i do stuff like this with live tooling on a cnc lathe.

[@johnspathonis1078]

The shapes machined by this process are not flat. They have a slight curve. The original idea behind this process is that these are flats to apply a spanner.

[@MrSky084]

Does my head in, attempting to work this out!!! Great work. BTW: Putting flat plate at more of an angle (from horizontal) when you cut it on the band saw, will speed up your cutting operation significantly.

[@1259bogs]

For most of the video I was thinking why would you want the cutter spinning the same speed as the part. This was amazing after I saw how it works! It’s too bad you basically need a whole machine shop to make the tool instead of just the lathe (which is all I have)

[@jwljwljwwwwl]

This tool is amazing, dont get me wrong, but you can just use a mill to square or hex cut with much cheaper tooling.

So other machinists just joke that they don't have their square endmills on hand to machine square holes, and you go and do it? Also, can you use this (or similiar) method to create square holes too?

[@warmesuppe]

Yes a planetary gear set can do polygonal holes. Its nothing new to be honest.

[@dimitar4y]

nah sadly a round cutter can cut an outside square, because when it moves linearly, it makes a linear cut. But internally the minimum "corner radius" will always be based on the diameter of the cutter. You have make a round hole then broach it or scrape it to shape. No other way around it. However, there ARE techniques for cutting odd shaped holes, and a custom square endmill might actually do this... Like a trilobe hole maker...
