We are trying to program a rough & finish cycle with radius compensation inside it but the machine does't seem to like it. It gives us an alarm.
What is the problem with the code here?

Thank you for your help.

Can you tell us exactly what the alarm code is? (Full text of the alarm message please)
At first look it looks like you are reasonably on course, but the actual alarm will help point out where the problem is.

You must write NAT2 front of G81 and change G87 NAT2

Ah YES, the G83 shape definition for NAT1 is only required for the roughing cycle, not req for Finishing Cycle (G87).
Good pick kurmay.
I have only used the G83 shape definition a very few times as most of our parts are ex bar stock and have no need for this coding.

hy i run a quick test on your program ; comp. and auto-chamfer does not work together, even on comp active and radius=0; if comp codes are eliminated, than program works

in my opinion, just rough without chamfers, and do them on the finish pass

if chamfer is big, than you may rough it on last pass of the rough tool > this eliminates some unnecesary movements and reduces stress on finish tool, but requires a bit more coding

for a better reply, just share part drawing / sketch / photo and data about tools that you wish to use / kindly !

Here`s the alarm we have.

same program work perfect on 7000L but it is not working U100L. Interesting.

I experienced a problem like this.

[deadlykitten]

yup i also received error on comp start-up ; comp & G75 don't work toghether

Duly noted!
Thank you for all your replies.

You may be having an issue with the size of your G75 L value. If you are at X4 and move to X5.5 with a L of .75, the chamfer is as big as the move is. This may cause a problem depending on the comp value in the register. Get rid of the G75 if it is just a line so to speak.

Best regards,
