  I did something by accident yesterday with some results that were pretty good. Using the milling advisor program from Helical to generate speeds and feeds for a .5" 5 Flute endmill I used the 9076 RPM 314 IPM and .06 stepover recommended for mild steel for 4140 which called for 8320 RPM and 205 IPM at a .035 stepover. Didn't think a thing about it while the endmill was in the cut because it all sounded right and the load meter was consistent at 85 to 87% peak for the complete cut without variance. Later I realized what I had done and this has me wondering what the real top end for Adaptive is without losing to much of my tool life.

  Had an old time Mastercam guy over for this and he was real nervous about the speeds and feeds so we started off slow and after a pass or two I jumped it up right away to full speed. Needless to say he was in shock and figured that what we did in 19 minutes with no discernable damage to the endmill under 10X would have taken him 1.5 hours using the traditional feeds and speeds he is used to.

We have had soms discussions on the forum. With adaptive most of the time the machine will be you limit. Or in feed, block processing time or in spindle power/speed. Most serious cam systems have something like this, but almost none as good as the AutoDesk CAM Adaptive Clearing in house developed! Where many is bought in made to work with the software here the software was almost based on it. 😉
