I would like to use elliptical interpolation in my Hitachi Seiki VA Machining running under Fanuc 6M-B.
Is there a G-code for this ?
If not, how should I proceed ?

Thanks,

Perhaps you should use CAD/CAM to generate an elliptical tool path.

I have this software for ellipses. Saves money on a big CAD CAM system if you don't already have one. CNC Mate :: Engineers Calculator

Do you need a true and perfect ellipse? If not, you can approximate an ellipse with 4 arcs. That is how paper draftsmen used to do it. If you search Google for "4 arc ellipse" it will bring up the technique.

Attached is a VB program which will generate GCode for an ellipse.

Greetings!

I badly need help for generating G codes(G03) for a CNC 2-axis lathe for turning a ellipse out of a rod. The Rod dia is 12 mm and the ellipse (Full Ellipse) size is 11.5 mm height and 20 mm width. The G-code required is for the section shown in the attachment. The start point is at 0,0 and continues in the Z- axis till 10 mm (Half width of the ellipse). Any help would be appreciated.

Hi,

Thanks for the reply. I am specifically looking for X, Z, I , K value type of stuff. Secondly, can you recompute the values ? The total height of the ellipse is 11.5 mm and width is 20 mm. The required size is for half ellipse: height 11.5 mm and width 10 mm only. Your code is showing total height of the ellipse as 23 mm.

Thanks in advance.

Hi,

When I open the G-Code in jviewer or SketchNC, I am seeing the following instead of a curved line

Attachment 264068


Is this ok or is some post processing required on the G-Code ?

Thanks in advance.

Hi
Is your software able to check arcing on the XZ plane?
I may not have converted the IJK correct to suit your XZ plane.
I don't have software to check for paths on XZ plane or for a cnc lathe.
Try this. I've changed the X to positive

Hi,

I used the G-Code in the software. The Ellipse curve is fine but there is one final issue - The Ellipse section is reverse. It needs to be rotated by 180 degrees (Clockwise). Can you do me one final favor by rotating it ? I need the ellipse section in the +X,-Z sector (as seen in the image attached by me in previous post)

Thanks in advance.

Hi,

Sorry, I was not clear in my post. Your G-Code is correct but there is a little modification required. The movement in the -Z axis is 10 mm and +X axis is 5.75 mm. When I plot your G-Code, the ellipse curve is reverse. Image attached below -
Attachment 264220

The ellipse section needed by me is highlighted by the green box in the image below -



Thanks in advance.

[Kiwi]

I didn't know there could be so many wrong answers.
I don't know why the curve is the wrong way around.
You may need to change the I/K positive/negative. (watch first line, I is different to others.)

code is for x(radius) not diameter.

Hello,

Thanks for the G-Code. Can you re-send the same suitable for diameter of 11.5 mm as the CNC Lathe operator accepts diameter only and does not know how to key in radius.

Thanks in advance.

Hi,

Should the code be from X-5.75. to X+5.75 while catering to the diameter ?

(I have no knowledge in CNC Lathe )

Can you let me know the software being used to generate the G-Code ?

Thanks in advance.
