MAZAK QT Nexus 250 with pc fusion 640t EIA program.
I feel stupid that I can not get it to work so i hope someone can help. I am cutting 13 pcs off a slug. The program is structured with a face skim cut, m00 flip then a sub to cut the 13 pcs. My problem is that I can not get the g50 shift to work. I have read all the books and done what it says. I am having to use a common varible to shift each part "ie X7.5 Z-0.100-#100" and add to it at the end of the loop it works but is a pain. after I post I have to add the varible to each line. I use G50 shifts on a Murata, and Tsugami with no problem. I added a sample program of how I have to do it. PLZ help

In your carse it's not a big problem since you have macro variable. But before I attempt suggest any change, my question is you want to shift 0.2792 in Z and reset it after 13 piece?

[03clipse]

Yes. I want to shift .279 for each part so there is 13 shifts. then reset back to the original Z zero for a new slug. I know I could use MAZATROL to do this and get the first and second side and all shifts much easier. But there is some geomotry that MAZATROL doesnt like to do and I would have to sorta trick the machine or lie in the program to get it done"if you do alot of MAZATROL you probably know what i meen". I feel stupid I have been doing this for 14 years and can not figure it out on thise dang mazak. I want to make it as easy for my operators as I can. Thanks for any help

[CNCRim]

Double check it, I hope that is what you want.

test - is without change work offset.
test1- is work offset change for particular machine.

[03clipse]

thanks I am going to try it soon as I get done helping one of the guys clean out our vtc 200c "time to change coolant". I use the if and goto statement on our OKUMA's when using the bar feeder and just use VZSHZ=VZSHZ-0.??? to make the offset never thought of that for the MAZAK. the line at start
"G10L2P0Z-8.55(Write the Z in work offset)" I never saw in the books Where could I find out more about it. and thanks

[03clipse]

on the test without change Z offset I will have to move the n2. I only want to face the first part off the slug. then after that the cutoff is my face. yes it is to break the part off i dont want an 8.5" part flopping around in there. I really like the way the program looks with the offset change. I will be looking for more info on that.
