I'm trying to figure out why a particular program runs fine in one mori lathe, but not another, when both have very similar controllers (both are Mitsubishi Meldas 60 series - one is a MSG-803 and the other is a MSG-805). The problem is that one machine will not activate tool compensation, and the other works fine. I have a bunch of flanged bushing shaped parts, of varying sizes, to produce, and have written a parametric program, that includes a couple of G71 roughing cycles for the project. Things are up and running on the lathe with the MSG-803 controller, however, when I transferred the exact program to the lathe with the MSG-805 controller, tool nose comp is apparently not working??? The obvious things like tool nose radius, and tool tip designation (i.e. 3 for the turning tool / 2 for the boring bar) have been entered into the machine that is not functioning properly. I don't know what else to check. As a matter of fact, the programming manuals for each machine are virtually the same, in regard to automatic tool nose radius offset. I may be wrong, but I'm inclined to think the problem is something other than the program. It is probably something really simple and basic that I'm overlooking. Any help would be much appreciated.

SL machines? A quick thing to check, do they have the same MAPPS software version?

System / System Config / MAPPS Software ( )

Denny - One is a CL-253 with the MSG803 controller and the other is a SL-204 with the MSG805 controller. I'm not sure about the MAPPS version(s). I just shut them down and am on my way out. I will be in tomorrow to get some set-ups done for Monday's production, and I will try to determine which version of the MAPPS software each controller has - Thanks.

Check the cycle format setting. F0 or F15. If a change is made, you need to power cycle the machine for the format switch to take effect.

I have 2 new NL's with Mapps3. I ran the first program this after noon in the NL-3000Y. The tool nose and comp worked fine, but as soon as the G71 finished, I got an alarm p160(i think). It has something to do with the cutter comp cancel and the return to tool change position. I am using an existing post for my Haas SL-30 that works fine. The Apps guy said it would run fine but it has alarmed every time I ran the part.

The program looks something like this:
TIP DIRECTION: 3 TNR: 0.0156 CUTTING X NEGATIVE
(2.00 SANDVIK DEVIBE B/B X 20in. BAR )

Does anything look funny.

I think the biggest thing I can't get used to is all of the door locks on these new machines. PITA!!!!!!!!!!!!!

the G71 line has P101 and Q103, the can cycle starts at N101 and ends with N102. I think you need to change the "Q103" to Q102.

That N103 was a typo. It is N102 in the program. I have Ellison working on it. They sent the program to Mori in Irving to look at it.

The machine finishes the cycle but alarms as it hits the clear point.

Try cancelling comp on a dummy Z move instead of the X move.

Are you getting an alarm or is it just over/under cutting?

this is an older post, so this has probably been fixed by now.....

also, on my CL's noes comp is not turned on during roughing, only gets turned on in finish cycle...G70 P101 Q102
when comp is on, any move straight up/down in X needs to be at least twice what comp value is.
