Hello everyone

This is my first post on this forum and i have to start with small problem.

Im trying to do a groove on OD of the pipe. The groove is shaped like a rectangle with roundet corners and unfortulately I don't know hove to program it.
I tried to use Manual Guide but then simulation is stoped before corners.


I working on 3 axis lathe with FANUC Oi-TC.

This is the program for something similar and also it's stop befor radius

I was attached a drawing where the groove is marked in red color.

If anyone knows how to make the groove or can make understandable sample please contact me

Your code look quite diffrence than from what I normal know, but you said Fanuc so I have some thing that I had done. You can try program few difference way, first try G107(cylinder interpolation), if doesn't work then try G112(coordinate interplation), G112 will require little twist but quite easy, CAM recommended for this.

Hi
Thanks for your reply but this program does not work.
The program stops on M69.

Hi
Thanks for your reply but this program does not work.

Do you get an alarm (such as Invalid G Code) when you try to run CNCRim's program, or does it just stop? It may be your machine doesn't have the Cylindrical Interpolation option turned on.

I don't believe his suggestion to use G112 will help you. That's for Polar Coordinate Interpolation, used for milling in the face of the part.

My ManualGuide-i doesn't want to run, so I can't help you with your program, but if you need to cut a part I can generate a "longhand" program to get you going.

[Rzadziu]

Machine just stop without any errors.
Can you tell me what parameter I need to check for turning on Cylindrical Interpolation.
Yes please if can generate program I will be grateful.

Regards
Marcin

[dcoupar]

I've attached a .txt file that can be called as a sub after you get the tool turning and positioned over the start point. I'm not sure about feedrates, so be careful.

As far as the Cylindrical Interpolation option, I don't have that information.

[CNCRim]

So, I am. I don't have that info. The example I gave you is worked and tested program(it was for Mori and Funuc).

Don't use M69
CNCRim what is M69 ??

[Rzadziu]

Hi

"decoupar" I tested this program and it works great. In fact, I had to change the feed because I was a little too small now I have a F200. But I have to You one more request, if you can generate the same program only with the start point in Z-4.5

Maybe my machine don't have some function.

[dcoupar]

Here you go. Start point at Z-4.5 and feedrate at F200.

[CNCRim]

CNCRim what is M69 ??

m69=brake off

[Rzadziu]

Thank you all for your help, the work done. Subject closed.

Hi

Can you help me one more time. I have to make groovs on face like on drawing.

[dcoupar]

I assume the red stuff is the groove? Do you have dimensions?

[Rzadziu]

Hi


This drawing is only for overview. I have many diferent dimension to do.
If is possible please make me a program with the possibility to change dimension.
For this one can be>

lenght of grooves 172mm
width of rib 10mm
pitch 1mm
