17:30 Thank you so much for documenting your crash. I teach machining and it’s a huge relief to be reminded of just how many things a machinist has to pay attention to. It’s a hard concept to understand that very little a machinist does is ground breaking: What a machinist does is stack things up higher than most other people. This and this and this and this and this and this and this and this and this is what makes a good part...

[@EdgePrecision]

Yes! Du to computers and design software things have gotten more complicated. On CNC machines like this there are many operations, tools and dimensions to keep track of. Any lack of concentration or interruption can cause a mistake. Just the making of videos and adding the camera work has caught me a few times. No matter how good or experienced you become you will make mistakes. Anyone that says different is lying.

[@Davemcmasters]

Videos are not long enough. I can watch machining videos all day long. Especially your videos. There is always something to learn. Great content!

[@MrLembnau]

big respect for showing that crash so we can learn from it too. other people would have edited it out.

[@JlerchTampa]

Peter is Human, a very very intelligent and thoughtful human that was kind enough to include a spindle crash for all of us to learn from, thank you! Also I'm amazed at the finish after the somewhat aggressive cut at 22:00. At first I thought the spindle wasn't able to keep up, but compared to the clean up cut at 22:30 it was just the variable spindle RPM vs Tool radius I heard. Simply awesome machine!

[@EdgePrecision]

The machine is running in constant surface footage mode (G96). So as the diameter changes the speed changes to maintain a constant surface speed.

[@465maltbie]

I certainly hope you have squared things with the customer so this set of videos doesnt get removed like the previous one. Thanks for sharing, great to learn from. Charles

[@neilsbardella3871]

Hi Peter, I'm wondering if someone makes CNMG tools that let you tip the head at 30 or 45 degrees for OD turning? If not, maybe you could machine a custom holder and make a video of it? Seems like it is a real pain to turn up close to the chuck with the head at 0 degrees, with the head at an angle you should have a lot more clearance. Glad it was a minor bump and not a major crash, thanks for another great video!

[@EdgePrecision]

Yes Sandvik does make some. I do have on for a CNMG insert that runs with the B axis at 45 degrees. But I don't have one for my finish tool. So even if I could rough there would still be a problem (in this case) with my finish tool. This also doesn't really help for milling. So you still run into the same problem with milling tools.

[@neilsbardella3871]

@@EdgePrecision Oh I see, I didn't consider the milling tools. Interesting, thanks for the reply.

[@viorel22cr]

I always wondered why you don't use the Mazak's toll measuring probe. You always touch up with a dowel pin.

[@EdgePrecision]

The mounted it so high on this machine it’s difficult to use. I prefer to touch off the tool this way I get a confirmation on the position on the display.

[@raider1628]

Great video!! I was wonder how much material do you leave for a finish pass for that vnmg insert?

[@EdgePrecision]

You saw it if you pause the video and read the mic. .010-.012" on the diameter. In this heat treated material that's enough to get a good finish. In softer steel I would leave more. Say around twice this amount. So if you are sneaking up on a dimension and want a good finish (in soft steel) leave about .030-.040" with the roughing and take a first finish of around .010" more on the diameter to establish your tools setting. Mic the part and change your offset for the finish size in one cut. Once you establish your setting move you rougher in on the next part to leave enough for the single finish pass with a good finish. You will, if you take a second small finish pass in mild steel ruin the finish. Unless you can run a much higher surface speed. So if you find you have to, speed up the RPM (or surface speed).

[@NeoHack]

Love the video, thx for sharing.

[@kwasg3]

Hi Peter, in previous vids you asked for noobie questions, here's one. I have zero experience on my bridgeport with flood coolant. I never see you clean the parts other than blowing a hole out or something. I would think even water soluble coolant needs a rinse, esp if there is any lubricating value helping the cutting and finish. Done parts seem to come out spotless and ready to go...?

[@EdgePrecision]

Generally for parts I'm using for tooling. I just blow them off and wipe with a rag. That's good enough. But the parts that go to my customer are deburred and cleaned in a part washer. Certain coolants or oils can corrode/stain some materials so they do need to be washed off. Molydee oil for instance can stain some materials. I have had this happen when using it to tap beryllium copper. Some synthetic coolants can cause corrosion on some materials. I don't think it's the coolant itself but it cleans off any oil residues that are protecting the metal from corrosion.

[@kwasg3]

@@EdgePrecision Ok, thanks for reply. I decided to buy a mill one day and started making chips. I thought I would make some easy parts for the hot rods I work on and build, and it is not as easy as you make it look! It is hard to be precise, so kudos and thanks for the great vids too, learning a ton.

[@comictrio]

I'm curious if the high pressure coolant flowing through the hole in the gun drill can cause mild deflection that could cause the drill to drill a slightly oversized hole?

[@EdgePrecision]

No the idea is the drill's tip lands ride on the film of coolant. This is why oil works better than water based coolant for gun drilling. So volume of coolant is better than pressure for larger drills. You need to maintain the coolant film. Sort off like a main bearing on a engine's crankshaft.

[@mlnunnari]

You should look at the 45deg turning tools from sandvik they keep your spindle away from the chuck. DCMNN-00115-12

[@EdgePrecision]

Yes I do have one for the CNMG tool but not for my finish tool. So it would have the same problem. This is good for turning but doesn't help for milling tools.

[@mlnunnari]

@@EdgePrecision they also have them for VNMG and VCMT tools aswell. Yea milling is an issue. I run a Mori Seiki NT 4250 which is similar to your Intergrex. I find shrink fit holders really help with the extended reach that's required.

[@billdlv]

Too bad about the crash with the chuck jaw but at least you caught it when you did in the cycle. You mention using Starrett ground flat stock, are these guides going to be heat treated?

[@EdgePrecision]

No I’m not going to heat treat them. It would be better but it really isn’t necessary. They work fine just as they are.

[@matthewferguson158]

What is that deburr tool you used your cordless drill on those holes? Looked like a ball end

[@EdgePrecision]

I usually us a spherical carbide burr with a 6" long shank. This can work where a c-sink can't reach if you have to come in at a angle. Just don't run it fast. And if using at a angle be careful it can ride up out of the hole and skate across the part. If you kind of pulse the drill it works good. It will chatter if run to fast.

[@hendrixh]

Hey Peter! Sorry about the light crash but, was wondering something, knowing that you run Esprit. Is there a reason that you dont model your chucks and jaws in Esprit and run simulation? I know that you make a lot of custom jaws but, for someone like you, it wont actually take much time to model them, even as basic rectangular boxes and save yourself some headaches? You are a great machinist, best of luck!

[@EdgePrecision]

The program in this video was made with no simulation. I have just recently started using the latest version Esprit TNG. In that version you have to have a model of your machine and use the simulation. You cant process code without first selecting a model and part setup in that model for simulation. The will provide you a accurate model of the machines you use for this process. This is absolutely the most accurate simulation I have used. Not only is the machine and all its components taken into account travel ranges of all axis but even the tools holders shanks of any kind and fixturing of any kind. You can model you own fixture with moving jaws spindles . Steady rest with moving jaws everything.

[@hendrixh]

@@EdgePrecision yep, absolutely. Thats why I asked. Im a TNG user as well and with our machine we always use simulation and its not bad, it actually a must for complex parts with custom tooling.

[@tedsaylor6016]

When you had that little hit, do you need to recalibrate/reindicate anything on the machine, or was the hit too small to affect things?

[@EdgePrecision]

No it was not enough to have to worry about knocking anything out of alignment.

[@danieltong9592]

What is the heat treated material you use sometimes for making tools? I have never seen that before. Thanks for the video

[@EdgePrecision]

It varies depending on the tool and its use. If I remember this piece was 4145 steel with a commercial heat treat. So that would probably make it around 34-36 Rc or 320-340 Brinell hardness. The drill guide plates function fine at the unhardened state of the Starrett ground flat stock.

[@danieltong9592]

Thanks for the explanation. I thought they may have been a bit more harder in Rc. You said it was getting cold there. Does working in hot temp have much affect on machine wear that you know of.

[@EdgePrecision]

On machine wear, no I don’t think so. It can make a difference if it was hot one day and cold the next day on the position of the machine. Some machines have temperature compensation. The Mazak has liquid cooled lead screws.

[@danieltong9592]

Cheers Peter, that intergrex is some machine.

How quickly do you need it, and how many downstream changes would be needed to improve the manufacturing? If you make a million, that's all where it's at. If you're making ten, sending more money to Peter might be the right trade off!

[@HH-Machining]

Thats a Bison chuck? I assume a steel body? Whats the diameter and how fast can you rotate it?

This machines turning spindle can only turn a maximum of 1600 rpm. Not enough to worry about for this chuck.

[@tmurray1972]

I would consider that just a little “interference rub”. A crash is when the machine has to be realigned IMO. Although if a rookie was running it and didn’t stop it, it would’ve been much worse. I’ve seen some bad ones over the years...lol.

[@tompetto5172]

Peter, i lost track of how many times i crashed on a manual mill. But shouldn't these "smart" machines foresee the interference themselves?

[@EdgePrecision]

If everything is defined properly and the safety work zones are enabled. Yes but it is a lot of work to keep changing the settings. If they would have a way to save different setups for different safety zones I would use it more. Otherwise I turn them off. And pay attention to what I’m doing. I should have been paying more attention to what I was doing. Instead of video production.

[@demandred1957]

For stuff like this it's a bit harder but I always SIM before running a program ujnless it's miles away from the chuck. Takes time, totally understand why would wouldn't bother for this, but mymillturn is 550k, I'm not risking that for 15mins programming time :)

[@EdgePrecision]

It's up to you. I just find that the simulation is good if everything that's defined in the cam software is exactly (and I mean exactly) the same as the machines setup. Even if its off (as in this case) a very little bit it does no good. It far better to just pay attention when you run the first setup. Witch in this case I didn't do. I normally watch this very carefully, because I know its a problem with this machine.

[@mannycalavera121]

@@EdgePrecision totally, not throwing shade. Even with SIM I'm still keeping a close eye on first off runs. Everything has to be on point Becuse it's quite often clearances are so very tight.

[@EdgePrecision]

Yes this solves the turning clearance problem. But not for milling tools. I do have a tool for the CNMG insert but not for my finishing tools insert. I tend to use the other tools because you can't use those 45 tools with the tail stock. Unless you put an extension on them. But in this case they would have worked.

@@westervonburgermeister9877 I think Aaron was referencing the engineer that designed it. I've made oil and gas parts that were quite complex, and then been shown where they were going.... I think there is definitely getting to be a divide between engineers and machinists, where design for manufacture isn't taught enough in uni's. The worst thing is when an engineer starts to think his part is more "advanced" or "smarter" by applying tighter tolerances needlessly, the whole key to being a good engineer to me is being able to apply the loosest tolerances allowable, while still allowing the part to function, through good design practises.

[@SuperAWaC]

@@matthewgowan7546 DFM isn't just "not taught enough" for many engineering degrees it's a completely optional or afterthought course now. I've even met mechanical engineers who have no clue how machine tools work, they are all theory and no practice.
