    Default Engraving using Radial live tool programming issues!

    Guys,
    I've got an ST-30Y and I'm trying to engrave on a barrel that's chucked up between the chuck and tailstock. Just trying to put some text along the Z-axis (G19 plane) and it's driving me nuts!! I used to do this as a 2nd operation on the mill with a 4th axis, using G107 Cylindrical Mapping. The equivalent on the lathe seemed to be G112, but I've had zero luck with that. The G112 worked great for me when I had to cut a hex shape on a part in the G17 plane, so I know: A) My machine works B) I'm not a *complete* idiot. None of my CAM systems have enough axes to just plug and play this job, so that's off the table. Would someone please post some code that shows engraving on the OD of a bar using a radial live tool? I don't even care if it doesn't use the C axis (I tried that and failed, too). Thanks!

    Hey, thanks! That actually runs on my machine. It's kind of clunky, though...seems like the C axis keeps putting on the brake during Z moves. That makes sense when you're doing serious cutting but a .010" tip engraving bit doesn't really require it. Wonder if there's a setting to turn that off?

    It probably has more to do with the resolution of the text. You could add an M15 to make sure the main spindle brake stays off.

    Not to hijack the thread but if you find a way to make G112 work in G18 or G19 I would be grateful to hear it. The code has to be output with Z changed to X, X changed to Z, and Y stays because its converted to C through G112. I haven't found a way to do it in software yet. Regular 3 axis mill code works for G17 & G112.

    I got it using G112 and G19.

    I'm using Mastercam with a 3X haas mill post. Its tricky but I can walk you through it.

    The code below will engrave a 1" tall letter D on a 5" cylinder. It does work. I ran it on our ST30 SSY.

    It obviously works, but are you actually moving the C axis with that program? Looks like it's just moving the three linear axes simultaneously with no rotation.

    Yes. If you run it on the machine you can see the C axis turning as its engraving. X stays at 5" diameter through the whole run. I didn't think it would by just looking at the code, but it did.

    Using G112, when there is a Y move in the program it converts it to a C move. When the machine is at X0. the wedge will only allow the Y to move +\-2.0". By using G112 Cartesian to polar transformation it converts the X&Y moves into X&C moves this allows you to machine around 5" diameter part even though the travel is only +\- 2.0" in Y. The machine itself is doing the math when you use G112. But it is less accurate than if you just used the X&Y as you would on a regular cnc. With G112 the tolerance is about +\- 0.001" at a 5" diameter. It get worse as the diameter grows from 5" because the resolution for the C-axis just isn't there.

    I modified a 3X mill post to swap the X and Z axes. I don't know what software you are using but the geometry for the D wasn't flat it was curved on a 5" cylinder, and I used a 3D contour toolpath to follow the curve. I could not get it to work if it output the code as G2 or G3 arc with I,J,or K. It has to be line segments.

    If you tell me what text you want, character size, and the diameter of the cylinder its going on I can post some code?

    Ok, I guess what throws me is that I'm not used to seeing simultaneous 3-axis moves for engraving. Normally it's Z down to the depth and then X-Y moves. Of course in G19 we're in the Z-Y plane and X is acting like Z (for those of use who are mill-minded). But it's still a bit odd that your X isn't just moving to a value and staying there while the character is being cut. I'd like to see the code for two characters and see if the X value rapids up between them. I finally got some code to work for my barrel engraving but I'm just using X and Y, not C. I guess I'll try doing a G112 but the main thing that throws me is that I can't find where to stick the diameter for the axis conversion. On the mill it's G107 and there is a Q value where up specify the diameter. Can't find an equivalent for the G112 yet... Sure, I'd like to see some code: text is: 50 BMG diameter is 1.150". Character height is .1 Thanks!

    Wow, thanks for all the effort! Only 2 things still bother me: 1) I can't seem to find ANYWHERE what the equivalent for the mill's G017 Q value is on the lathe. Maybe it just knows based on the tool offset? 2) I don't know why your program jumps back and forth between G19 and G17. I'm going to go out in the shop and play a bit and see if I can crack this nut!

    Setting 102?

    Yeah, I saw the G17s.

    I ended up doing a more lengthy test and took out the G17s. It input them because I'm using a 3 axis mill post to output the code.

    Here is a better video. I took the G17s out this time.

    The problem with the ST series lathes with a Y-axis is the spindles arent meant to function as a full fledged c-axis. That is why people have problems trying to program it like its a actual rotary axis. There is no code on the St series for the C to understand inverse time feeds like is present in true 4 axis programming. Also the c-axis brake is partly controlled in the firmware of the machine and it can be difficult to overcome its function. They are good for indexing, and accurate axial and radial machining if the work envelope is within the Y-axis travel limits. Anything else your best bet is G112 if you can work around it.

    Wow, thanks a ton for all your work trying to explain this. I still have yet to make anything other than just X-Y axis programming work, but as I get time I hope I'll zero in on the ultimate fix. Any chance you can post the code for your G112 example below?
    Thanks!
