Using G2/G3 instead of G1

[lazartamas94]

Hi!

Can u help me?
I dont understand how to use more g2-g3 instead of g1. Too much line in the generated program. 

I saw the entries about this problem, but it wont help , i mean "smoothing" "play with the tolerances" or maybe i screw it up. 

I added 3 pictures about the problem, the PP built-in, 2D contour settings, the generated program and a last from the project.

Thank you.

Would you be able to share your Fusion file here?

I can't remember why exactly but the Siemens Posts all seem to linearize arcs, If you create just a basic circle and apply a 2d contour path it outputs all in G1

283 lines of code for just the circle

If you post the same with Heidenhain its literally 2 lines of code to do the same circle

35 CC X+0 Y+0
36 CP IPA+360 DR+ F4000

I think I've fixed this in the past for someone, but cannot remember what I did, I would be interested to know why the standard posts are setup this way

OK

Looking a bit more into the post, Arcs are linearized if Cycle 832 is turned on, with Cycle 832 off arcs are output.

This may be due to this wee nugget of info from the Siemens manual

Whether The controller won't accept arcs with Cycle 832 on I don't know, seems unusual if that were true.

Are you actually seeing issues at the machine, or is it just that you would like to see arcs in the Code?

The Siemens control should be able to handle lots of  G1 segments no problems with Cycle 832 on.

It used to be said (maybe 15 years ago now) that all newer controllers liked linearized code. Now it seems the opposite is true. All our machines use linearized code and run just fine with great surface finish. But our machines are 15-20 years old.

Hi guys!
Thank you for the answers, sorry but i cant share this program but i have tried the solutions.

What works:

playing with the smoothing and tolerances (tolerance 0.01, smoothing 0.001)

i turn off the cycle832 and i got the generated program what i want

Why i need this?

We check the final product profile before and after the cycle832, there is no difference

but

the generated program now consists of much fewer sentences and it consists of much fewer sentences and is therefore much more transparent and takes up less space in the memory.

Thank you so much for the help and sorry about my late answer!
