Learning to imput G code today.

Had my first hands on lesson on writing G Code for a HAAS TL 1. Of course the first thing we did was to work on Barrel Tennon and Threading. LOL. Learned a lot and was fun. Made some mistakes but thankfully did not crash anything so that alone made it a successful day I believe.
Anyone here do there barrel work on a CNC here?

Love this stuff.

No barrel work yet but I don't have a cnc lathe either. I have a Haas Mini Mill in the garage that I make things on though. If you lathe control is anything like my mill control I suggest always running the tool path check before hitting the start button. I used to work at a machine shop programming and running Mazak lathes and mills. The programming for those was conversational and very easy to learn. One thing I found was that almost all of my mistakes were from fat fingering a button when modifying a program. After almost rapid feeding a tool into the 12" chuck turning 3000 rpm because I entered 2.0 inches instead of .20 thousands I learned real quick to always check the tool path.

I'm sure you'll do fine and it's fun to learn new things like this.

I don't know what we did today but there was NO chips being made! Err. Tried Canned Cycle for Threading and kept getting an Error code for the X Axis being out of bounds. Lots of head scratching and frustration in that 3 hours. Sigh... Learning the Hard way.

Make sure you didn't flip flop an X- to an X+ or something along those lines. I believe you are limited as to how far you can go down below X centerline or X0 If you will.:)

Do you have another program in the memory that has RH threading in it? If you do, download it, get the two programs side by side and compare. Looking at the same lines of code, over and over, you can go 'snow blind'. I've done a bit of barrel work (profile tapering & chambering) on a TL, but it and the other CNCs stay busy making real money. So, I go back to the manual machine. Might not be as fast, but its just as good. Robots are 'cool' , but they have their place, IMO.

You must have a death wish by spinning a 12" chuck at 3000rpm and rapiding a tool towards it without verifying your code. If you are going to keep your lathe that way I'd restructure your code so the spindle does not start until the tool reaches the starting point.

Someone should seriously consider changing that lathe's parameters that limits spindle speed.

Did you home the machine? What about your tool offsets? Are they set for your tools? Read up or you will make a mess of things. http://www.cnccookbook.com/CCCNCToolManagement.html This is the first one I found so I don't know if it's a good read or not, but it's better than nothing.

Some controls will accept both radius and or dia inputs for the X axis. Seems you need to crack the books. you will find it more productive than trying to teach yourself CNC by filling a bucket with broken things.
