Re: NC look ahead
and everything worked fine until it gets to a bit where the cutting and repositioning moves are small then it slows down
hy stevie, this should be normal : a cnc is never moving at a speed greater then the program value, thus real feed <= programed feed
a toolpath is a serie of geometrical entities, and the machine will never show an alarm if entities length is too small for the nc to reach the programmed feed; in such a case, motion gets succumbed, but it should keep on going / kindly
ps : imagine what would happen if an nc would stop when programmed feed is incorrect : an important fraction of active machines would suddenly breakdown however, you should be glad that you have noticed this behaviour, because it is the begining of a new path, that leads to a programing style that creates continous cnc motion; if you would work on an okuma machine, i would start to share you a few tricks; unfortunately, i can't help with tips for hurco, thus i don't know if hurco has methods to deal with this case
