Mazak/Fanuc Help
Hey everyone,
I am having some trouble setting up a M5 with a first generation 6 control. I have the program manuals and that's about it. What I really need is the operation manual or the parameter manual for this control.
Basically, I cannot get this thing to cut a arc properly. They do not use the r code, instead they use the I and K codes. This is fine and dandy, but even when programmed as such, it still does not generate the arc correctly. I am thinking that a parameter is set wrong, but without a parameter list and description I cannot identify or change anything.
Any help would be MUCH appreciated.
Oh and I only recently bought the machine so I am still working bugs out.

Are you programming in absolute, and specifying the I J values as relative positions, as I believe this is the method the 6M uses.

Is This Similair To The Mazak M4 Twin Turret Lathe With A Fanuc Controller? If So, Can You Post The Block Or Program With Which Your Having Problems With? Maybe I Can Help You Out! or Have You Tried To Use An r Value Instead If The I And K Values? I'm Pretty Sure It Doesn't Matter With A Fanuc Controller Which One You Use.
I Hope This Helps.
On the other hand, You have different fingers.
Better question would be what is it doing right. LOL commanding a corner radius it cuts a complete circle. Is like it is reading radians rather than dia.What exactly is it doing wrong? Alarm out? or wrong dir.? start stop pos.?
This is a 6AT fanuc, not a M. The I and J are incremental are they not?Are you programming in absolute, and specifying the I J values as relative positions, as I believe this is the method the 6M uses.
Yes it is a twin turret machine...ie: T1101 and T2101 and the back turret is negative. Here is block using a comp for a .031 r tool nose cutting say a 1.00 corner radius:Is This Similair To The Mazak M4 Twin Turret Lathe With A Fanuc Controller?

This machine was pre-r command so it can't be used.
A while back I had a Victor CNC flatbed like this machine and I had a heck of a time building a post processor for that machine as well. I am old and can't remember like I used to, but I had to massage the parameters pretty good to have it function properly. However, I may be doing something relatively wrong that is just plain simple and I am not catching it.
So please helpppppppppp and thanks alot for your responses guys, I really appreciate it.

Yes, I and K would be incremental looking at the arc start pos. from the arc ctr.
N105 G01 X1.9380 Z0 F.0080
N106 G02 X4.0000 Z-1.0310 I0 K-1.0310
so in the case above X1.938, Z0 would be the start pos., G2 cw arc ending at X4 (or should it be X2.969). should be:
N105 G01 X1.9380 Z0 F.0080
N106 G02 X2.969 Z-1.0310 I0 K-1.0310
or
N105 G01 X2.969 Z0 F.0080
N106 G02 X4.000 Z-1.0310 I0 K-1.0310
depending on o.d. of part to create a 90 deg. arc on an o.d. corner?
( if had I had a print of what your making maybe I could be of more assistance. looks like more of a prog. issue than parameter)
