fanuc 16mb high speed machining

[Poxino]

In certain areas of the toolpath there .01mm movements, in fact is where machine slows down most , I have run just a fraction of that program for testing, from memory, and is slightly better, but it still slows down a lot.

It's not the feedrate in the code that is slowing you down, it is the sheer volume of code being processed through the DNC (Dripfeed).

What are your Line/Arc filter settings?

That is what I was suspecting, we had that problem trying to run HSM code through a drip feed at my last job.

I will upgrade my machine memory this weekend , as I had issues on getting an sram card(for parameters back up) that actually works on my control, then I will be running programs from machine memory only.

But at this stage, I hope to be wrong, but I believe that toolpaths I want to run are "too modern" for the actual machine capabalities , unless there are other parameters which need to be tweaked, the max speed I am running these toolpaths is around 100ipm 2500mm/min.

Hello guys,

Just an update, after many weeks I managed to get my 2mb memory upgrade done on my machine.

It still does not make much difference in terms of motions, machine still struggles a lot where there are many small movement to be processed (0.01mm segments) , slows down about 80% of the programmed feed rate or more.....

Any suggestions, or I just need to forget about it as the machine and control are too old to do what I want to do?

Maybe play with the filter and tolerance settings in Mastercam to streamline the code a bit?  I usually run a .0004" total tolerance and 20% filter for surfacing.

I use solidcam which has a similar feature, but again it does not seem to be any different

Can you post some of your code?

[Matthew Hajicek - Singularity]

Looks to me like the filtering could be improved.

[Poxino]

How do I do that?

[Matthew Hajicek - Singularity]

In Solidcam, I have no idea.  In Mastercam I would try opening up the filter tolerance a bit.  I'm working in inches:

 

[Teh Bear without Brains kinda idiot]

I have run HSm on slow machines .

I ended with using such principles

Lower RPM ,Slower feed with bigger side -off milling

For stainless I used to go up to 1/3 of diameter  and slower feeds

I even used High speed mills with hsm toolpathes

More aggressive filtering  you can filter up to 0.1-0.2 mm and even more if you have enough material for finish
