Radial Holes (Circular Pattern)

[patrik_stellgren]

Hi

I've been trying out the BETA  Siemens MillTurn PP in F360.  Im Using the " 2X Turning with Live Tooling " Example part in the library.

Looking at the Radial drilling operation with circular pattern, it looks like the PP is creating a separate operation for every hole instead of like the Axial drilling further down where the PP just outputs the C-axis moves.

Now is this a limitation of the CAM software because of it's changing the "coordinate plane" or is it because of the PP?

I've tried the Fanuc and HAAS post and they did the same thing. It would be nicer to have it more like the Axial code.

Radial Drilling Code: 

MSG ("; Drill5")
SETMS(2)
G94
G97 S2=500 M2=3
;Machining from X+ G19
G0 SP1=180
G0 X106.68 Y0 Z-5.588
X86.36
F254
MCALL CYCLE81(43.18,22.86,5.08,14.505,)
Y0 Z-5.588
MCALL
X106.68 Z-5.588

I agree with you that that output would be nicer but the current output at least works.

It's sort of a software limitation that a drill cycle can't go around an axis. So doing this with a pattern would allow us to make a sort of "hack" in the post to still create one cycle.

Since this is a little tricky to make and relies on what the machine it capable of I think the post development team didn't want to put this in the generic post.

You could ask a CAM reseller to implement this or try an edit yourself(With the forum help of course.).

I did a Siemens Emco Millturn postprocessor in the past but I never read that you could put a rotation into a Siemens radial drilling Cycle, but I agree with Laurens, would be kind of a hack to get it out of the post. The post does not output much information about patterns
