Hail Guys!
In the near past, My experience has grown a lot in intelligent roughing techniques. By the way I have started to face the high table feedrate related problems such as clattering in high feed small corners(basically during aggressive direction changes[toolpaths are generated with Edgecam 2013 R1]).
I have two VMC-s equipped with Fanuc 0iMD control which booth are supporting AI advanced preview control/AI contour control (G5.1). I have already set up a set of parameters to eliminate all the ballscrew destructive acceleration/deceleration habits during high feedrate operations on these machines.
So My interests are the following:
1.: How does Okuma OSP U10M controller carries out axis (Feed not Spindle) acceleration/deceleration when no high feed functions are enabled(Just asking because it seems to Me that Okuma does not make any clattering or undesirable axis loads during the above mentioned conditions, meanwhile Fanuc 0iMD would definitely damage the ballscrews in high feed operations without using acc/dec control function in a continuous production)
2.:What are the applicable high speed machining functions for Okuma OSP U10M control? I would really appreciate an understandable explanation next to them, because the manual is not always the best thing to understand with its convoluted sentences.
3.: Is it healthy for the ballscrews if I use High Feed programs (F3000 mm/min maximum) without programming any direction change smoothing techniques on an Okuma ESV 4020 VMC equipped with OSP U10M control? (Tool path generated by Edgecam does not always the smoothest, when used on Fanuc 0iMD it makes clattering noise in sudden direction changes if programmed without AI advanced preview control/AI contour control enabled)
By this way I am tempted to start another thread about the above mentioned Fanuc functions because there are some phrases in those manuals as well which would be nice to hear translated to understandable format. And there are a lot of things to ask about, like parameters, working of predefined sets (G5.1 Q1 R1-10). I think I will just leave that for tomorrow.
Please forgive me for the poor selection of words in some cases and generally for my English!
