Thank you as always for taking us along!

Hand writing G code on the fly like a boss!

[@Rubbernecker]

Or looking at a sheet of paper and punching it in.

[@paul5683]

​@Rubbernecker I would say a little bit of both. We used to keep cheat sheets at the machine that would have what was a functional program written in black and white. Then by using an existing written program in the control one could easily adapt that program to what your new part requires. The nature of most cnc programs is that there are a lot of start up sequences that have to be included in an exact manner or the machine just will not even start. No problem with it crashing because it was showing an error code before the spindle came on or any slides were even moving. That's where the cheat sheet was handy because you could go from the very beginning of your new program and compare to what was written on the cheat sheet to determine where the mistake was made. But for the most part all you had to do was change the starting size and then the geometry of what you want to end up with, that was what was in your g71 line. G70 being the roughing cycle and g71 being the finish cycle. G72 and g73 were the boring settings for the turned part.

@@Rubbernecker Even if that’s true, the button punching speed was impressive. Clearly someone who’s been doing it for years.

[@BruceBoschek]

James, you are truly an artist! Watching you enter code in is like watching a great orchestra conductor. Thanks for another great video.

[@ThomasGriffin-zn1rr]

Wow VTLs have came a Long Long way from the 1948 Do'ories VTL I worked around 20yrs ago , these are Way more faster & efficient than WW2 technology ! Thanks

[@寶寶-n8m]

Great job man The coding was so impressive

[@GLAJMAN]

There is something very cool about forged chunks of metal :). Thank you for the vid.

[@randypiper7485]

I was gunna say, this guy must be a boss level haha, Because I only know certain codes. But not how to design the code program needed fit from scratch. Lol, that's dope!. I use to run a Haas VF2 for a couple of years. Fun gig.

[@Zappyguy111]

Holy crap those metal forgers are good at their work. You want 450Ø × 450H? I've gotcha mate.

[@SirHackaL0t.]

‘Groove here’ *starts the Saturday Night Fever dance*

[@hinz1]

Toolpath simulation available, on that Fanuc? Otherwise I find it rather scary, to run hand g-code directly, especially on such a monster machine. My old Fanuc3T sucks particularly hard in that regard, if you forget a "." it thinks 0.001mm instead of mm ;-/

[@catsmr]

Thanks for the explanations!

[@ronsullivan132]

Brings back memories, except I had a 60 inch chuck and would do pump castings that will fill the entire swing. OM machine

[@descent815]

Good job. I do have one question as to why on the jaws of the machine did you not put some kind of insert so when you clamped down the product it didn’t gouge or put gouges where the clamps tighten down on the project so that you don’t have those gouges? Is that not something you’re worried about at all because you want to redo it over again or what?

[@ColKorn1965]

Very good surface finish my friend!☺

[@Xris-FJ1200]

Many thanks for this new video xris

[@fupersly]

Thank you for sharing. Would it be possible to show how you center the work item? Always curious with castings and forges

[@BobBeatski71]

With such large pieces of metal, do they need to be set aside to cool between processes or can you run cuts from start to finish without a break ?

[@xsarchitect]

I'm disappointed you didn't show skimming the parallels before machining second side

[@lonelyplanet1080]

i notice some markings on the machined surface where the chicks were tightened onto the work piece....ahould there be a protective material between the chuck jaw and machined work piece?...to prevent such markings?

[@Woodnsmoke]

Thanks for sharing! Do you have to babysit the machine all the time? I imagine some of these cuts take forever if you just gotta wait on them? 😅😅

The CNC Stanley Cup!

[@LANless]

Super cool, thank you for sharing!

[@IsZomg]

5:58 I can hear those chatter marks lol

[@brianpreston8483]

I ran a bullard very similar, differelnt controls. I always liked it

[@Awfultyming]

Awesome video. Can you show inspection? Thank you for sharing

[@paulmoloney5569]

Nice work as always

[@Chris_L.]

Why do some operations need cooling fluid and others do not? It all looks quite warm.

[@Smallathe]

Very impressive 😄👍

[@rosewhite---]

I never wanted to try run a vtl as I can't understand how tall parts can be gripped securely!

[@ypaulbrown]

what would Lumpy Rutherford have to say ???? ''Gee Beaver.....that is massive, Right Wally''

[@davidwoodcock139]

Could have done that in a lathe

[@7-BitesPatrick]

I thought you were typing an email on that thing-ie. 😂

[@warehouseman6325]

Very nice job

[@ВладиславДанилов-р4ч]

Внутренний диаметр на стенке сделали, а полом по "черному" в ЧПУ поставили зафиксировав по не отработанному!??? Почему не сразу???

[@bdude92]

Any way to reduce the chatter on the button insert tool?

[@FrancisoDoncona]

How come no one cleaned up the floor, good help is hard to find.

[@xsarchitect]

My company bought a youji vtl and said they can't reach table in Z, making some sort of riser just to be able to run parts on a brand new machine, somebody is lying

[@CraigLYoung]

Thanks for sharing 👍

[@olukayodeokunowo4631]

Great! Thank you for this great video more grease to your elbow

[@MurlWatne-io2bo]

Why do they call them lumps?

[@MegaRich7]

Bit risky when you're not chucking onto the part securely and taking 5mm depth of cut when the part is that long. Look after yourself.

[@MalcoJack]

[@christopherskipp1525]

Can one machine magnesium?

[@BLenz-114]

With lots of coolant, probably.

[@christopherskipp1525]

@@BLenz-114 Thank you.

[@robertlanders5723]

You do NOT use water based coolant when machining magnesium… If burns EXTREMELY HOT if the chips catch fire. It burns so hot it will break down water into its composite elements (hydrogen and oxygen) which will accelerate the combustion process. Special fire extinguishers should be present when machining this potentially volatile material. NEVER USE WATER TO EXTINGUISH A MAGNESIUM FIRE !!! I’ve seen lathes destroyed (melted) when a fire erupts.

[@alansawyer1219]

Play nicely

[@GeeTheBuilder]

All these million dollar machines and they still flip parts over using a strap and two bits of wood to cushion it. 🤷‍♂️

[@Jack_Rabbit71]

Worlds slowest tool changer ever!

[@paul5683]

We didn't even have tool changers on our cnc lathes. Cutting 4 inch diameter S7 we could only take a little more than the tool nose radius for a depth of cut so our cycle times were pretty long. Using a quick change tool holder like the Aloris brand, we would find that our tool offsets held very well as long as you didn't crash the machine. S7 was hard on the carbide so making sure that there was fresh inserts in the tool holders was key to success.

[@matthewryan3380]

Shitty finish on it

[@noodles7011]

are all your machines Fanuc? After 30 years of being a fabby im learning CNC now on a Fanuc run Mill. Your videos are great because I understand the operating system

[@jamespark_85machiningtv]

All machines are fanuc.

[@paul5683]

Most of the older g code / m code controls operate similarly. All of them need a little start up sequence to tell the machine what you are doing like are you working in metric or sae, which direction you want the spindle to turn , do you want coolant, etc. Once you learn and recognize those pieces of the program you can read almost any program just like a different language.
