I've said it before and I'll say it again; Peter you are ,by far, the best, most precise and accurate toolmaker I've seen in my half century of machining! And then to top it off, your running a graphic simulated tool path simultaneously with the actual machining operation so we could know what was going on, was beautifully done! Thanks for sharing your deep knowledge.
Good day to you fine sir, My company has purchased me a Haas 35-LY lathe for my inventions, creations, abilities to think out of the normal box. In this, we will spend around $200,000.00. I will understand this machine sooner than later. I have ordered Mastercam, I have been using Mastercam design for a few years. I always have pressure on my shoulders, then solve the problems. In this new pressure, I also will not fail. I believe that I have seen everyone of your mastery videos. I think similar to yourself, you are very unique, thank you for your video's. I will create in my own way, but, I enjoy seeing how you think. You are very special to this World. Sir.
The sound that the "second roughing drill" made upon entering the material is possibly the coolest machining sound I've ever heard. Maybe that was just the result of speeding up the video though, haha.
Enjoyed this a lot. Long time subscriber and I remember some great series you had on your channel which were taken down because of non-disclosure issues. Happy that you can finally show a similarly complex part again from start to finish. Actually I started a job as CAD/ CAM engineer at a company making mainly one-off and small runs of large parts which most often have gear teeth of some sort. They have indicated that all work is under NDA so everything stays within the company walls. I am learning Hypermill which is currently only used for milling but will find its way to turning. An Integrex or two would fit the shop very well and I think we will definitely be heading in that direction. My career move has most definitely been inspired by you (and others) so thanks a lot. I hope we will see videos from you for a long time.
At first when you milled with the tilted vise, I thought you were pushing it into deflection, but then I realized you were getting some four axis action. Good video, thanks for keeping it up!
Hi Peter. Another impressive video. Really appreciate the editing, the overlays etc as others mentioned. No BS just really informative and interesting. Nice touch milling the conical on the clamps. Always look forward to the next video. Keep it up as long as it's worth it to you. Thanx. Be well.
It's funny how I watch so many videos where I think to myself (admittedly in a delusional way): "yup, if I had that [shop, machine, time, equipment] I could do that". Somehow you have the biggest, fanciest equipment of any of the creators I watch, and those thoughts never cross my mind when watching your stuff. Thanks for the video.
Apologies if this has already been covered but 2 things really caught my attention. first, you didn't really verify the part was in the chuck straight. You indicated the outboard end but not the inboard end. You then dialed in the chuck when you (possibly) should have tapped the part into alignment before adjusting concentricity. Second, the gravitational error of sweeping the part for centerline could have been a couple thou, so unless you take measures to verify, you won't know. A good touch probe is far better than a dial indicator. In our shop all the horizontal mills have probes so we don't need to monkey around with indicators for position.
You must be new to my channel. I have covered the gravity error of indicating in the horizontal position many times. This indicator and arm I use in this machine I have tested and verified the error. But yes you are correct there can be an error with some setups. As to the runout error with the clamps holding the back parts face solidly back in the jaws (in this setup) it is holding the part perpendicular to the chuck. This wasn’t the first part I did and I did check that the lathe operation had turned the parts perpendicular on that end to the other (the one I’m doing). But again you are correct this error can exist where the part could run true in one place on its diameter and not in another. If it isn’t running perpendicular in the chuck. As to the probing.The way they built this machine it only has -10mm of X axis travel before hitting its limit. So here again you are correct a spindle probe would be best. But with only 10mm minus travel I can’t reach the bottom of the part with the probe. So using it can’t be done on this machine for this purpose. I hope that clarifies your questions. Thanks.
If you jog at a high rate into the part & brake the indicator or probe, it's guaranteed you won't have spares in stock, and it'll be late on a Friday afternoon.
Dialing around the center every now and then, probably couldn't hurt. But just out of curiosity, I was under the impression that the main spindle's center is always a consistent value away from X and Y Home. The only way it could basically change is if the definition of Home got reset. Like if the travel limit stops moved at all.
@@EdgePrecision That's a bit interesting. Neat. I work on 4th and 5th axis machines, and the center of rotation of the tombstone, is next to never checked. Only if something knocked into something, it would be.
Thanks for another great video peter! Useful to have this intersecting hole trick in mind. I would like to ask if you ever used any 'abrasive flow deburring' to deburr internal intersecting features like this?
You ca buy on Amazon the connection for hypodermic needles. I just bought threaded one and mounted it in a blow gun. Then I could buy off Amazon needle blanks to mount in the air blow gun. It really is handy for this and blowing shavings out of tapped holes. You can buy all different sizes and diameter of these needle blanks. All with the same connection to put on the air gun.
@@EdgePrecision Hey Peter, love the idea and was trying to find the adapters on Amazon. "Luer Lock" is my best guess of the adapter and needle style from what I could find pictures of. Does that sound familiar? Thanks.
On reason is this machine doesn’t have any more than -10mm X axis travel. So I can’t even get the Haimer probe on the bottom of the part. Also I prefer swinging the indicator around the part. With this short arm and indicator there is extremely small error not really enough to worry about. If I really wanted to streamline things I would purchase a Haimer centro gauge. I have seen this gauge and concider it precise enough as a coaxial indicator.
Sorry, I don’t use the Mazatrol part of this control at all. There are people here that use it and are very good with it. And even they say the milling part or Mazatrol is limited and for complicated stuff they prefer cam software.
@@EdgePrecision Yeah, I've found this as I've been using mazatrol recently to make fixtures for the company I'm working at. I think it could be a combination of the software lacking ability and the fact that I don't think we have paid for all the options on the software. thanks for responding.
Hi Peter, One question, do you use dynamic offset when you're using the vise? Or different work offsets for each indexing? Just got our new Mazak VCN-700D with a Sankyo roller cam 4th axis. I'm planning of adding a tombstone and a vise very similar to your setup. I'm trying to think of something more fail proof than using centerline rotation or multiple WCS since I'm not the only one operating the machine.
This machine is older and doesn’t have the dynamic offset option. So for this setup I positioned the part in the cam software in relation to the C axis rotation. But if you have dynamic offset option it would make things easier.
Nice work but it's getting a little redundant for us advanced machinists, we know how your machine works and how to do setups, you should shift gears and switch over to the programming side for us guys that are wanting to learn new software, I am a Mastercam / Gibbs guy but would be interesting to see some of the actual 5 axis programming in Esprit. Also Peter keep in mind 60 to 70 % of the comments on RU-vid are AI generated bots now, so don't fall victim and cater to the bots.
Are you kidding? Peter's work is in no way getting redundant to me, but I'm a CNC manufacturing engineer who uses tips and ideas he shares almost every week!
There are still some old guy's, and inexperienced guy's who don't believe the modern techniques, ideas behind using air instead of coolant for roughing steels, what's your opinion since I know that you rough out with air all the time? I am a tool and die machinist, we use air to rough out tool/mold steels all the time for injection molds, and the RU-vid channel "CNC Frezar" uses nothing but air on mold steels also, really makes me wonder why there are still a lot of people that don't use or believe in this system, thoughts? I think this could be a video of interest that would benefit not only the newer guys on your channel, but the older machinist that don't believe in the modern techniques.
When machining steel with carbide tools sometimes coolant can make the carbide breakdown. But this does depend on the tool and how you are using it. On a High Feed Milling cutter for instance it is better to use air or even better if you can introduce some mist into that air. But flood coolant just makes the inserts fail sooner. I have also noticed a similar thing with Ball Endmills in steel. Particularly this is true with steels that have a higher carbon content. But if you need the coolant to help evacuate shavings then you need to make a balance of some sort. Do the machining such that the tool doesn't experience a lot of temperature changes. In other words keep it in contact with the material as much as possible cutting to keep heat in the tool. I have also found it is better to mill full depth with the side of an endmill taking shallow radial depth of cut if possible. Like what some programs call Adaptive machining (My software calls this Profit Milling). Rather then taking peck depths down in the Z axis with higher chip loads. This would be more like old fashion type of milling with HSS roughers. Carbide likes to get hot and stay hot wile cutting. The only area this really doesn't apply is in exotic materials like Titanium, Inconell, Nickel alloys and maybe some stainless steels.
@@EdgePrecision You should make a video on these concepts for others future reference, Its still a debatable topic, that in my eyes shouldn't be debated anymore, its concepts have been around for a couple decades now.
