16IA 16Ib

[Bluesman]

Ok folks here is a fun one, I got 2 Kitamuras HX500I, These machine have the absolutly identical CNC program in them. I have a 2 min cycle time difrence between the 2 machines the 16IMA is slower than the MB. I have been thru the parrameter manuals and they seam to me to both have the same look ahead capabilties and also the bell curve rapid feature.
Is it psoible there could be a 9000 parrameter I am missing. It is driving me nuts, Fanuc is no help and Kitamura of course is no help. I ahev been thru parrameters and every time i think i find the right ones i match them to the MB control but no chance. Any answers out there

HI M8

what do u mean is slower?

waht is slower the buffer or the movements of the axes?

and i think is a 900 parameter that should be active but this is an option as u know.

let me know exact maybe i can help u


GOOD LUCK!

More info is needed. Is the program running off memory or DNC?
Have you compared feed/rapid/overrides parameters? How long is the fast cycle time? Give as much info as possible.

I been all over this thing, I am not sure of its a buffer issue or an axis issue, But here is more info, I have the identical CNC program in both machines. The A control is 2.4min slower than the B control.
I have compared all the standard feed and max rapid parrameters and they match, However the 1400 series and the 8400 series parameters that control the high speed functions and settings for the "high speed conture control" the bell shaped rapid and all the like.
These parrameters do not macth, BUT if I set them the same there is no change. I am still missing something.
I am running from the control there is no DNC

I can send the parrameter manuals to anyone that needs them

thanks Bluesman

How long is the fast cycle time? Are the actual feeds the same on each move block? Break the program down into sections and compare the cycle times for each section, so you can narrow the problem down. If I were there, I would probably find the cause in a day.

I agree you need to break it down further, could be rapids, could be ATC, block processing speed, corner tolerance window, finish signal time of something etc.

How about mechanical factors such as different inertia, lubrication issues ...

Ok *******, A day??? I been a Fanuc guy for 30 ****ing years. Fanuc cant tell me nor can Kitamura. I have broken it down tool by tool line by line segment by segment. Please if you cant help the go **** your self but do not be a smart ass. This is not a simple problem. You got to be one of the ussless ****s that think they know everything.

thanks for the help. Bluesman

Yea, I looked at all those settings too and matched them all to the faster control. This aint my first BBQ guys.

Thanks for the help, Bluesman

I thought about that, One of the machines is a HX500 and the other is a HX500I could there be mechanical difrences between the 2 that are just what they are and it wont change no matter what??

Maybe, thanks. Bluesman

I do not know if the following info is related to your problem:

FANUC NEWS no.173, Dec. 2008, on page 4 informs that a new function has been introduced in series 30i/31i/32i - model A which results in a higher speed canned cycle for drilling such as G83. Basically, they use a higher tolerance for positioning (in-position width) at R-point and intermediate retraction points, and a tighter tolerance at the bottom of the hole. This does not affect accuracy because accuracy is not so important at intermediate points; it is important only at the bottom of the hole. Thus cycle time improves without affecting accuracy.

I get that you are frustrated. I have been a field service engineer for longer than you have and I still ask others for insight. And yes, if I were there, a day would probably be enough: I have that much confidence in my skills and knowledge.
I also noticed that you don't like to answer specific questions, but rather rant and rage and be abusive.
Have a great day.
