I’ve seen a lathe turret attachment recently that works like a mini shaper. Looked like a live tool that turned rotational motion into linear motion.

@@Thorhian Was the motion on the cutting axis done by the attachment, or by the lathe carriage? e.g. was it a mini-slotter attachment? Just a passive tool that worked like what Peter showed here?

@@somebodyelse6673 The motion was done by the attachment. It was used in a Mazak Lathe Video kzfaq.info/get/bejne/eLxnpsWl2dGuoqc.html

It's the only way to get the sharp mitered corners. If I did it straight in with a chamfer milling cutter it would leave a radius and not get into the sharp corner.

As they say, you can make anything with a shaper… besides profit:)

Correction. Harbor Freight sells what they call an anvil for 50 bucks. It isn’t really a anvil. It’s not something a serious blacksmith would use.

I have used this cutting style quite a few times in the past. For instance if you want to cut a internal keyway or a spline. In some of my emailer videos I show removing sections of a ID thread to make sort of a breach closure or cutting around a internal integral key in a bore. To establish the sharp internal corners the endmill could not do. So yes it would be very useful to have a cycle in Cam for this.

I'd be pretty happy just to have a shop into which it would fit! 🤣Assuming you meant the Integrex, of course.

@@pyrobeav2005 I meant the anvil, but I would love a big mazak

I used the manual program cycle. But even that won’t completely work, because you can’t do a manual milling cycle with the spindle stopped. The Mazak will give an alarm if you define the tool as a lathe tool but command the milling spindle to start. But I found out this. I could program the cycles with the spindle running in Esprit. Then select all the cycles their settings edit tab and tell it they don’t have the spindle on or a spindle speed. It will then process code without the spindle commands in the code. It even shows the spindle stopped in the simulation. If Esprit would let me define a square milling tool. It would even simulate the material removal accurately. I may check with support and see if that’s possible.

@@EdgePrecision as of 2021 R3 there is broaching specifically supported in Esprit. I am not sure how it would best apply on your broaching cycle. I haven't used it much. A custom macro called via manual entry is how I usually handle it.

@@oostburgjblok I’m using Esprit TNG here. If they had a method to define a milling tool I could even simulate it. I did define a adaptive item of the tool. But there is no way to add a cutting edge. I can define a lathe tool I their software by moving the insert I the correct position. But it won’t let me select the lathe tool in the manual milling cycle. It doesn’t even show them as a selection. But what you saw in this video was completely processed in Esprit TNG. No edits in the code afterwards.

Yes it carbide. I made it on my grinder.

Ah, I see how you did the other hardy hole now. I just have to translate that now:)

I made (Ground) the tool on my grinder. It is a special tool.

It’s the same tool I used for the large anvil. I don’t think I made a video on the making of this tool. Maybe I showed something in the large anvil videos. I can’t remember.

@@EdgePrecision I went back to watch the old video, you did show the simulation of grinding the part. I didn't know NumRoto supported grinding non-rotating tools as well.

@@purerhodium there is what they call manual grinding paths. That’s what I use for these kind of tools.

@@EdgePrecision If you have the time it'd be interesting to see how you program that.

@@purerhodium There are modulas for Numroto that I don’t have. I think one can grind things like turning inserts. But I have ground all kind of lathe tools with what I have. You just have to sort of imagen them as a single flute tool. Then make a fixture to hold a insert as if it were that single flute location. Or I have ground boring bars like micro 100 tools. If you do a manual move where you grind a diameter. Sort of like a wide groove in a round blank. I the manual grinding path there is some settings to offset that path in all axi. But if you offset the tools rotary axis off center. It will grind that groove so to speak with its axis off center of the rotation. This way you can grind the shank relief off center like a Micro 100 tool has. Then use some more manual moves to grind the cutting edges of the tip of the bar. Just make the simulation what you want and it will grind it. You need to experiment with the manual grinding path and the end tab that has the offsets. Sort of like fixture offsets on a normal machine. Maybe I can do a video showing some settings for these things.

Yes it is moving .010” away on the back stroke. And feeding in .002” per cutting pass.

It’s just two pocket floor finish passes with a one way linear cut directions. One at 45 degrees and one at -45 degrees. I tried a zig zag pattern but it didn’t do that without some passes going across at some weird angle that didn’t match the pattern.

This kind of machining puts very little load on the machine. It doesn’t even register on the load indicators. There are far greater loads in normal milling, drilling and turning operations.

Just a regular 60 degree single flute engraving tool.

I was making them for a 50,000 sub giveaway. It's been taking so long. It may have to be a 100,000 sub giveaway instead.

It’s my names initials.

You are getting a distortion due to the cameras wide angle lens and the view angle. The tool is taking .002” off each cut and backing off .010” when it retracts. So as not to drag the cutting edge backwards on the material. Believe me all the cuts are the same.

@@EdgePrecision - You are one of very few people on KZfaq that I actually believe when they says "believe me". May you always use your powers for good!

I’m not sure I understand. Are you asking how repeatable the tool changes in the spindle? If that’s it, it’s closer than the machines positional resolution.

So repeat selection of a tool will be spot on?

Yes. Within the precision necessary for machine work. Nothing is spot on (As you put it) perfect.

No he had his made where he is. His are just mostly square blocks of steel.

Typically it is used by a Blacksmith. But I suppose you could try to throw one, if you could. Its kind of heavy for that.

Whenever you like.

@@EdgePrecision thanks Peter will stop by sometime. Bill is starting to move slow. But I love having hime around.

Not on this machine. It is designed for this. It has a special coupling in the spindle designed to take the force of turning tool on it and not on the milling spindle. That said this would actually put less force on the this spindle bearings of a normal machine than milling or drilling does.

Thanks Exotic! Glad you watched.

Well right now the steel isn’t really heat treated. It’s not soft sort of like a comercial heat treat. If I got the anvils induction heat treated on the top surfaces then this would be a proper anvil. I may look into that.

Do you feel better now? I’m glad I could help Sorry.

Because of the tool marks? Nah, the finish is good for a machined part, and phenomenal for being done with that many axes. The tool marks on most of it look so faint you probably couldn't find them by touch.

Hahahaha, do you feel better now. Made my day with that comment.
