Hi, im wondering if this is even possible.
Need to make a circle motion in xyz at the same time
i have a bowl and im gonna mill 3 lubricating grooves.. 360degrees/3
so the first groove is only in x and z axis and i use g18 so that works well but the other 2 grooves i have to move xyz all at the same time in a circular motion, is that even possible?
Do i need to manual program like 100 vertexpoints for this to be possible?
sorry for my bad english

Using a Mazak VTC 20-B with Mazatrol Mplus

G02/03 is possible only in the three orthogonal planes.
You may cut the three grooves after rotating the workpiece by 60 deg.

I'm having a hard time visualizing your part. But would helical interpolation work?

You should be able to program that. You can move a G02 or G03 in XYZ simulatenously. For example:

G20
G0 G17 G40 G49 G80 G90
T1 M6
G0 G90 G54 X1. Y0 S15280 M3
G43 H1 Z.25
Z.2
G1 Z0. F6.2
G3 Z-1. I-1. J0. F61.1 <-- Cuts a helical motion, moving in XYZ
G1 Z-.8 F6.2
G0 Z.25
M5
G91 G28 Z0.

Code G49 C120 will rotate the orientation and then run your G18 code you used for the XZ Plane
Then cancel with G49 and then G49 C240 etc.
Note this is for a Fagor controller,

Fanuc G68 does the same.

Hi,

Do you have a (3D) drawing or an example for what you want to make ?
Normally you need XYZ coordinates when you only have 3-axis, generated by CAM-software.

G68 method did not occur to me.
Thank you.
