Modern CNC Machining on a old CNC Lathe 

Hi, I'm actually the guy that emailed you about the toolholders for this machine a while ago, look at your email I replied to you. I have a Fusion post that I have modified to give me usable code to run on mine. The biggest hurdle your running into is that this control doesn't actually use work offsets, these use work shift coordinates that you put in the code on your G50 line. Programming a Fanuc OT is different than any other control I've used but after I figured out the quirks mine works great.

You sir are far more invaluable to us than Titan. We all bunch poor farmers with mules. No combines.

My man, Good on you getting the machine running! Old school CNC lathe men like me hand program the code. There should be sample programs in the books that you received in the machines. Every machine tool builder adds their formats/idiosyncrasies to the control. But most strait forward turning code should work. If this machine uses G28 or G30 (safe index/home) that will get rid of that alarm when you try to index. That lathe has a very tight work envelope. So be very careful when indexing and moving the axis under program. Ride that override knob and turn all the rapids down if you can. Try this as a sample program. It should start up, select a tool 1, approach, face the stock, return to home and end. O5443 G20 N1 G97S1000M03 G28X0Z0 (test this carefully) T0101 G00X2.1Z0.0 (Rapid for 2.0" stock) G1G99X0.0F.003 (face stock) Z.050 G00X2.0 G28X0Y0 M30 That should work and get you up and running. Most lathe jobs do not need Cad/Cam unless you are doing some very intricate shapes with tricky intersecting points. Most lathe jobs are bushings, pins, plugs, fittings etc. Once you write some good code, you can just cut, copy and paste proven code from one program to another like a template. You will need to interface a PC/laptop with the control. I am sure you know and have done that before. Best of luck and I hope I have been a small help to you!

Wow this video brings back lots of good memories. I worked at dial-up internet service providers back in the day and still deal with the ISP's 30 years later. All we had was racks and racks of modems before the digital equipment like 56k came out. Nice find of machines you come across. Love the content.

Nothing better than a big crate of stuff to look through!

Instant advice for a bro: remove line numbers, spaces and zeroes before periods. It will increase data tranfer rate for about 40%

hey man!! open up your fusion360 post processor - the cpp or whatever file format i cant remember (opens in visual basic) search for where your axis are configured - aka search Aaxis etc you will find where the axis are difined in the post processor - Now - you will see (1,1,1) this is meaning X, Y, Z you can take the axis from positive movement to negative by changing (-1,1,1) would inverse X axis, (1,-1-1) inverst Y axis and (1,1,-1) inverts Z axis - this is for 3axis post processor - have a look in the turning fanuc post you took from fusion

I look forward to you sharing the solution after reading all the comments from people who have run a similar machine!

I was in engineering when my company first started to play with CNC machines (a few decades ago, U.K.). Mostly press brakes, sheet punch presses & plate profilers (oxy/fuel gas, plasma). Fanuc was THE name at the time, for quality. An old machine was one of our first (4" holes through 1/4" plate in one hit), using holes in a paper tape. I got out, when I realised I could read the holes. Yup. "I've been here FAR too long...!" 🤣

I like that you show them actually working to and not just start and home.

I used to use a g30 on control like that. So my code would look like O1515(prog num) N1 (rh turn tool) G30 u 0 w 0 t000 (t000is offset cancel ) G50 x 5.0 z5.0 s1000 (x and z theoretical distance set by 736 parameters) (s1000 is spindle limit) T0101(01 is tool number and second 01 is offset number Always clear these when setting up) G96 m3 s500 (for steel) Here's where your actual cutting g code would begin I used to use a post processor called predator editor any way your video just brought some memories back. Good luck

Hi, I had a similar problem on a Doosan Lynx 210 with the Fanuc Turning Post Processor at first. When Posting the NC code I had to alter the Safe Retract from G28 to G53 and set the Home X and Z position. Without the adjustment, my program would over travel at the beginning of programs and tool changes. And I had to unselect "Use Cycles" in the Post Properties because my Lynx didn't come with any Canned Cycles. Hope this helps! Love the content so far!

Loving the content man. Suggestion for future - get head or chest mount for gopro so you can use both hands and still shoot content. Happy new year!

Oh man that is awesome I ran a mazak years ago for 9 or 10 years I loved it

For a while i have the same control and i am learning to use it now soo... -use 'dry run' when testinng , then the G0 is also variable with your feed override. Keep it slow-don't crash it! The MX0 workshift ( i learned from someone who knows these controls very well) : use this to make a drill to be on centre with the chuck and a x offset for this tool of zero. Then if you pop in a drill you just fill in offset X=0 for that tool and you can drill. (! After MX0 recalibrate your toolsetter in the parameters.) MZ0 works on all your tools (as does MX0) so if you have your tools properly setup then you load one,touch of your workpiece,then MZ0 input and every tool has the right z offset for that workpiece. Made some parts so i know this works. Calibrate your toolsetter is a thingie... In short....: Mount a tool- choose tools and select toolno. touch the tool off on toolsetter. then again load the tool to import these offsets. Turn some part in x. read display. measure size.Calculate difference. Change this in tooloffset. reload and check for same size indication. (its confusing so you can correct the wrong way etc) The correction value needs to be added/subtracted in your parameters to correct your toolsetter. (4 parameters , x inside , x outside etc)Touch of again. Reload tool. Check.... Took me a day to get it done as you make so many mistakes! But now that works its a great machine. Because it is so compact way of programming i think its worth learning iso. I think Fusion will just flood this control with too much data. I am not so far to test that yet so what do i know...

I custom make post processors. The last one I made is for a 1995 protak mx3 and mx2 mill. Zero errors on arcs and events.

the fusion post processor forum on autodesk forums is golden for this

wow super knowledgeable viewers.

funny that this was put on my feed.. i just last night in my pajamas finally figured out the post from fusion to my 1989 milltronics lathe at 11pm went in house couldn't sleep lol ran 3 parts just to be sure LOL

this is where acorn retrofitting comes in handy.. Its got all the pin outs for old fanuc based machines.

One place I worked at, we had an Amada Pega 358 CNC punch with a Fanuc controller. Every program was loaded from floppy disc via a unit on the front. We ended up hooking a PC to the RS232 port via a couple of adapter leads. The PC was set up to communicate with the Fanuc. Thus, we were able to access the programs stored on a networked drive and start the transfer process. All we needed to do was load the program from the controller as we would from floppy disc. The controller had no idea the program was stored on a PC.

Can you film in 60fps to maybe stop the screen blink? Just wondering if that might help.

One word of advice from me would be to have you post processor modified to remove any redundant/unnecessary code i.e. G00>G0 G01>G1 G02>G2 etc.etc. if the control will accept it that way. Those old fanuc controls had VERY little memory and it adds up VERY fast.

At where I work we have a Mori Seki Sl-15 it’s a machine from the 1980s , that machine use the faunac system we use master cam however to program the machine

I always made my program around the tools that I had

I never touched a CNC but love your content! Those machines are cryptic for me, hopefully my 3D Printing skills helps me to understand what is your challenge here. Was really cool to learn that USB->RS232 modules exist to wake up those awesome machines. What are the machine brands you recommend which are more suited to be used with modern Fusion software? Something like Haas for instance? Thanks for the great content ! Cheers from France

Sometime I do my best Diagnostics on some problems getting in the car and driving home a lot of times I figure stuff out I have to turn around and go back

Those jaws look like uncut soft jaws. Rule of thumb you don't want more than a thou difference between the radius of you part and the radius of your jaws.

Great video.. im interested in the dnc box . Could you please share some details abbout how to get one .. thx

I highly recommend learning how to use canned cycles like a G71. Fusion 360 does not produce canned cycles for lathes and makes extremely long programs that you will eventually not have enough memory to run. Also, if it has macro b, learn to utilize that. If you stick to Fusion for bulk code and can use macro b as well, only have “N” numbers on the tool changes or important blocks of code (such as GOTO or conditional branching) as it will help free up available space in memory for usable code. 😊

Br cautious when setting your tools on x. The point where you touched off is not 0. You need to account for the radius of the part when entering the offset to get the zero on centerline with the spindles axis

Is that an old Miyano lathe? I've worked on a ton of DNC and OEE implementations. Love to see these older machines getting upgrades to allow them to continue to be useful as technology progresses.

Fanuc 0t really benefits from being a rather prolific control. There is plenty of information on them easily available. That said the flexibility of them does cause issues. Like the g54 issue... some 0t controls are configured to use offset tables, others only g50. These configurations by the machine tool builder (mtb) make it difficult to have an 0t post that actually works with all 0t controls. As an alternative to editing the post you could take a look at the fanuc 0t parameter manual. Although i would work on the post first. Is your machine utilising A,B or C format for its gcode? Usually there are options on the post screen in fusion that allow you to select things like this. There may also be a g50 option which would omit g54.

You cant spin the spindle in the other direction? M3/M4? So that you can use all the tools ?

First thing I see people wanting to do is throw that word upgrade just do with what you have and get it figured out

FAN-IC

What do you think about Okumas and taking old Okumas to run on fusion 360

Sir, that is like daily life for me😅. Its easier to use DNC server on pc, and if it has no port - usb to rs converter. You can presset in ap many machines, auto save improt from external sources or cloud, drip feed etc. No clunky expensive brick to move around and take off spece on table. Note 2. Communication settings are in parameters, if you have parameter manual

How I buy these type old cnc machine

I program Fanuc 0T manually into the console on a Colchester tornado if you want to look at any programs I have written I’d be glad to help

Hi dude, I run a fanuc OT A control, I use fusion to spit code, I found a suitable post processor after a ton of faff, and I also have to manually edit the output to remove the g codes it doesn't like. Happy to help if you want

I had to use one of my t-nuts to fix my truck I couldn't hold the nut in place but I can put a t-nut in between my fingers and slide it up in there now one not short of a full set

At some point would it be possible to put a modern controller on an old machine like this? Would it make sense?

I always had the computer sitting right next to the machine and wired it directly sometimes a faster baud rate does not work on an older control

Fanuc 0T is the simplest Fanuc system. I have worked many years with it, but only in 3 axis machines. But why not get a Usb to serial cable adapter directly from your lap to the machine Rs 232? It is so cheep, these adapters. Cheers.

I can try and help you if you want, I used to run a Daewoo Puma 350 lathe with the Fanuc O-T control but i don't have a post processor as i would just program the machine by hand The O-T control on your machine is a little different but they should work about the same as each other

use a generic fanuc prossesor, and you'lll have to erase he g54 code it spits out. my YCM doesnt use the g54 fixt offset my lathe has a fanuc 0T as well ::EDIT::: also for more information, i had to reach out to the company, and get all the M code and G codes that were set for the machine, and its likely going to be the same for yours. just give them the serial number and the have all the documented info on it. it was pretty cool knowing it was tracable

Have you tried letting ChatGPT help you out with commands, postprocessor etc?

You buy old machines. I'm having a hard time trying to find a turret shaft for my Yam CK1 it's a 1989 it runs great but the shaft broke. If you run across one.

To touch off x it’s Mx (the diameter) It wants simple gcode

double check some basics, lathe v DNC v Fusion , are all calibration units: inch - inch, mm-mm…just thinking out loud :)

I had a machine at first I did not do the g50 ofsset boom plowed right into chuck.

That Spindle sounds rough

Just throw a Allin1Dac from centroid, should be a relatively easy retrofit

You have to run g code one by one. And then see what code is not working. After you can edit the g code. Is the fast solution. The hard solution is try to see if the machine can do circular interpolation using 2 axis at same time

It looks like i am in a similar situation, that is, i have an EMCOturn 120, with the original TM02 Control, which is slightly different from the EdingCNC Controller i run on my other Lathe.. But.. i can write Code that Postprocess the Code for EdingCNC to EMCOtronic TM02 Code, so i just have to write a program with Eding G-Code, and run a simulation of that, and have it postprocessed at the same time.

When will the new video be??????

When are you coming back to fix g18 I no what it is I cannot explain it

It is possible that there is no G54 etc. This was still optional with very old Fanuc controls. The control may only have one workpiece zero point.

You can actually call FANUC on this and they will support you. No charge during normal hours. You should use tape input and drip feed it so you are not program space limited.

to use that tool setter {tool eye} it works just like homing the machine. you hold the jog button till it slows down and touches. when you pull the setter out, the screen that comes up is what enables you to use it automagically. they are usually little cubes. but maybe yours is Z only, or i didnt get a good look at it??

What state are you in?

You said you wouldn't keep this machine, Would you be thinking about selling it?

Your g54 is your fixture offset you probably need a g53

Probably need a g53

It's the axis movment ztox xtoy

you probably need to edit your post processors to remove all the g-code that doesnt work on it, "nyc cnc" do some tuto on it if you are ever interested

Can you write the program on the machine?

150 lb of pressure can exert a few thousand pounds at the chuck

OKUMA FTW

BewmBewm!!

I thought you sold that machine right away but I guess I missed something

I said that about the bar right before you got to it hello my guy I can't get a job because nobody wants to hire me because I'm too old

You just have to edit that program and take out that code

drop me the manual i edited some pp for Fusion in past. Greetings from Germany

Without those manuals these machines would be just scrap. You should attempt to digitalize them and share them online for other people to use, or even for yourself. In case you ever damage or lose them.

You can never have enough tools and Tool holders

Please like, guys. 30k views, and only 585 likes…. 😢

what about a cheap Chinese controller

Lathe programs are easy, just fingerbang it.

lsk is communication error

If you were doing more than a test cut you would bore those jaws

Hey mate i have a post for fanuc ot if you need

Might need a nee controller board and a raspberry pi or similar 😅

Have you got Fusion post processor configured?

these lathes use a master tool system. all tools are based off the first tool you setup. so if you move/change/reset the master tool it fucks up ALL of your offsets!!!! this is why i use a bar stop as my master tool. I never take it out the turret, and it doesnt wear or crash. watch that olson kustom works video! he shows you the modern way to set these turds up!
