I am having a seriously frustrating issue with cutter comp. I am running a fixture with multiple parts and the first 6 parts run just fine, then I get to the seventh part and I get an p/s 041 alarm on the lead-in.

Code 041

Interference in CRC

Overcutting will occur in cutter compensation C. Two or more blocks are consecutively specified in which functions such as auxiliary function and dwell functions are performed without movement in the cutter compensation mode. Modify the program.

I dont think I really understand the wording of this alarm as I havent encountered it before, can someone explain it to me in a little bit more layman terms?


This is the section of program that it happens in:

/G01Z-.4F50.0
/G42D31X15.3112F8.526
/G03X15.9388Y-6.I.3138J0.

/G40G01X22.6488

6 parts before the alarm run fine, I have checked the math, the leadin and leadout.... I am just really stumped.

Edit: Forgot to add Im running a Hardinge VMC 600II with a Fanuc 0-MD control.

Not an expert on your control, however, think the control is looking ahead to this line:

/G42D31X15.3112F8.526

So the other six parts contain this line?? The "D" is dwell or cutter comp offset?? Some controls require a "dummy" move when invoking cutter comp or turning it off. Seems error message doesn't like G42 D31 together. Would like to see what the code looks like for the six good parts, or I could wait for someone who has same control as you, who knows EXACTLY what he is talking about, lol, sorry, had to reply I have felt your frustration in the past.

D is my offset value, the move from my rapid point to the point in my G42 line is my lead-in.
This is the first six parts that machined perfectly.

Well I hope you're happy.....two of us stumped now, misery loves company???

Worth a peek??? At least it explains your error message in better terms.

Youre using a .5 end mill so you must have .250 or more movement to deactivate cutter comp. you have .2499
one more tenth and it would work. Or you could change your D offest to .2499

16.1887-15.9388=.2499
change X16.1887 to X 16.1888

Thank you so very much! I combed over the numbers a couple of times but still seemed to have missed that math

Gotta love the little things with CAM software lol.

[SCRAPWOTSCRAP]

I was told there would be no math!!! lol, good job, golf clap issued.
