I guess if you wanted more than these it'd make sense to either trepan the worst of it or get custom blanks cast.

[@EdgePrecision]

Open die forging closer to finished shape. Like the power hammers you see blacksmiths using, only larger. That would be best. There are places here in Houston that do that. But that would take to long in this case.

[@CallerNumberNine]

Wow. As a non machinist I baulk a bit at the cost of stock "wasted" in the process of roughing out a part like this. Machining out of one piece of stock must be preferable to fabricating these from a flange and shaft which were welded together, or else that's what we would see done in a commercial environment. But I'm curious; is machining from one piece done because it is structurally necessary or because the material cost of one big hunk of stock less than the fabrication costs would be making these out of a two pieces?

[@EdgePrecision]

They did fabricate the first ones. But had a failure. As to the cost. I don’t know. Welding 4140 takes care this in itself would be costly. But it could save on machining time. So it’s hard to say. Now a open die forging. That’s the way I would go. But there wasn’t time for that.

The O/D of it or the mass of it ? If you want to centre on mass, then spin the work and have the chuck auto adjust based on eccentric vibration.

You should have used one of those fancy high feed turning tools that feed away from the spindle. Probably would have taken a quarter the time to rough.

[@EdgePrecision]

Sandvik prime turning. No not exactly. Let’s investigate this. You can’t do the depth of cut I’m doing here. I’m doing .250 depth of cut at .015” per rev. So let’s say you go with .050” depth of cut. (You can’t plunge in to much deeper at the shoulder) That means you have to make five passes to my one. To do that you would have to feed at .075” per rev. This is a very high feed. Faster than a 16 pitch thread. Just to do it in the same time. And those inserts are not as strong and quite a bit more expensive (everything Sandvik is). So to do it in 1/4 time would be impossible. I have spoke to people who have actually tried this style of machining. They say under the most ideal circumstances it can work the way they say. But it’s not all they say it is.

[@joshualegault1095]

@@EdgePrecision Just do some research on it instead of guessing. You can take way more than .05 depth of cut. The inserts last longer and the whole point of it high speed material removal. Their website kinda sucks or I would look it up for you. They want you to put in your info and contact them. It's newish technology so there's not a lot of people out there that have video or content put there about it but what I do see look pretty good. It's the same concept as radial chip thinning on endmills or axially on facemills. Sometimes old school can be better though so you may be right

[@EdgePrecision]

@@joshualegault1095 Ok but I know what they say. I have seen their data. But I have never used the tools myself. But I do know do know people that have. For them it didn’t work as well as they say. But you claimed the cycle time could be cut to 1/4 of the time. This is what I’m disagreeing with. Just do some computations even at twice the depth of cut I mentioned at the same feed. It would only cut the time in half. I am thinking that the inserts would give trouble at that feed of .075. Even with feed mills you rarely feed faster than .025-.030 per flute. So maybe it can be done but I don’t have the tooling to try it.

[@joshualegault1095]

@@EdgePrecision alright I'll do some calculations. What's your sfpm diameter of stock and length and we can just choose an approximate diameter to turn down to. I'll make 2 programs in fusion. 1 at your speed feeds depth of cut ext. And I'll make one at the speeds and feeds recommended on sandviks website since I just found it. I did a trial run of this and the time for the prime b is 20 percent that of the speeds and feeds and depth of cut I'd expect you to be at.

@@EdgePrecision U can use SUMITOMO T-REX TRM551712 GU AC8025P insert in PRIME TURNING always, way cheaper, great results. And T-REX insert style is way older than Sandvik prime inserts.

@@breadbutt That really depends on what kind of endmill it is and the coating of it. And what kind of material it is =) For this operation coolant shouldnt be needed. Some endmills run a lot better/longer without coolant, but they're usually run with air instead of coolant to get the chips out of the way. Evacuation of chips is a big deal.

Impressive material removal peter. I was thinking something along the lines of the guys with the trepanning idea, we used to have a work where we would face grove as deep as the face groove tool would go and then part it with a normal grooving tool, creating rings. We actually used the rings for the parts, would make 3 different diameter parts from the stock we had, were much smaller pieces of course :) and it was brass. Not sure you have face grooving tools that go deep enough to make it worth while in such massive stock. Here it would make the process much longer, you would have to remove the tailstock and hammer the ring off every time, probably the time waste not worth the material saving.

[@jimsvideos7201]

You could mill two slots and get half-circles, although they wouldn't be useful for much.

I wonder if an enormous core drill (a bit like the concrete ones) and a super-sketchy parting operation could let you keep most of that removed stock in one piece. Probably not worth it but would still be interesting.

@@squeegied3rdeye713 Casting one-offs is a bit easier than forging, as nowadays you can actually produce your pattern with styrofoam or 3D printing rather than wood like the older way, but there's still the fact that casting isn't always foolproof.

[@EdgePrecision]

For this few parts the cost of doing that would exceed the value of the scrap. Also the time it would take to make or acquire the tooling to do it would be to long. One other and even more important issue is there is no way on this machine for me to even do that kind of machining operation. There is no way to properly mount and support the treepanning tool. So for this customer who was in need of the parts on a shorter time schedule. This is the most economical way to go. If there were more parts and time a open die forging would be the way.

Thought the same. The lathe could get torn and bent by the lift in case any fixture element is forgotten to put off. 😫

Слава Петров somehow came to my mind... ;-) Using forged pieces would make it faster and cheaper material-wise, but the cost of forging would be probably much higher than 400 kg of this material turned into shavings. With bigger batches, like, say 40 or 400 pcs - yes, it might be worthwhile to use forged "zagatovki", but not for a batch of just four pieces, I reckon. Also, as others pointed it out already, time is money, especially with those expensive machines, so any "economising" here would be like spending a dollar to save a dime. Split pieces design? Yes, unless specs called specifically for monolithic "dietal".

Wow...I didn’t realize how heavy the stuff I work on is....I did two 15” diameter by 210” long shaft for a car shredder...if this chunk is 1300lbs.....that means my rough stock weight was around 12,000lbs! No wonder use 10ton overhead gantry cranes hahaha

[@SuperAWaC]

This is why I advocate machines having their own jib cranes instead of trying to save money with a communal lift or having just one bridge or gantry crane. Jib cranes save so much time and effort

[@EdgePrecision]

If the machine can handle a part or fixture weighing more than say 60-100 pounds it should have a hoist. It is also a mistake to put a 1000 lb hoist in a machine that can handle 4000 lb. put the correct size or someone will overload it!

[@SuperAWaC]

@@EdgePrecision I visit lots of shops with a bunch of bent engine hoists sitting around

[@garys9694]

You can't always store the parts in close proximity to the machine. So, if you have to transfer the part one or more times in order to machine it you gain nothing. Normally a jib crane has a very short distance it can travel.

[@SuperAWaC]

@@garys9694 that's why you put the parts on a pallet and then move them around with a pallet jack or forklift.

My grandpa use to co own a farm equipment dealership. There was a table there that I ended up with. It was made back in the 60s and the insurance made them get rid of it about 2015 so I got it. Its 2’ by 3’, 4” thick solid steel. An anvil table. I cant even imagine how much it weighs. It was sitting upside down on concrete blocks when I got it. I slid it and it destroyed those blocks.

Customer order do from one piece and noting else. A piece made from a solid block is always the strongest, but also the most expensive and especially for something like this since there was so much material to remove but the customer knew what he wanted no matter the cost.

[@curtisvonepp4335]

@@dtiydr Yes the - customer is always right but is with over kill .A welding engineer might save him from over kill .Yes welding can be stronger than the parent metal i can tell you for sure it would work with a correct heat treating process. 🧐

[@bcbloc02]

@@curtisvonepp4335 That is what I said in another comment but probably after sending out for heat treatment after welding the additional cost would negate the material savings of doing it from billet instead of a 2 piece welding.

[@Z-add]

So 95% of the material is wasted. Isn't there a better way to do this. Like start with cast iron of roughly the same shape and then mill to final shape.

[@EdgePrecision]

Cast iron isn’t strong enough. They originally made this part by welding two pieces together. They had a failure. So they decided to go this way. Because of time constraints this is the fastest way to go. There isn’t time to make tooling for castings even if they were strong enough. Or make forgings (the best way to go). I don’t think people who make these comments understand the economics of the situation. Yes if you have enough quantity of parts and the time to make the setup for dedicated material for those parts. Than ok. But for just a few parts it’s less expensive to just machine away the material.

[@salahzenieh2515]

I'm estimating that this is 14"-16" at the largest OD. Since the video is sped up so much, one gets the impression that the rpm is way high. If my assumption is correct, you would probably be running the spindle at 160 or 140 rpm. Am I close? It would be great if a part of the clip would show the real-time speed. The fast clip is also cool- 3 hours shown in 10 mins. Your videos are amazing and the attention to detail is outstanding. Thanks you for sharing your experience. Respect!

[@salahzenieh2515]

I just read the description- it is 16.15" OD!

[@EdgePrecision]

Also the clip in the video where I overlaid the machines screen. If you look it shows the rpm at the 600 sfm of the first pass.
