I'm surprised that thing can change direction so quickly without inducing a following error. Great video. It's amazing how far HSM has come in the in the last decade.
@Ahnyx86 This was just a 1 time test to find the upper limits of the endmill grind. I would never run this machine at this rate under normal conditions. On the stainless piece the spindle load meter was reaching 150%. We have an opportunity to test on a machine with 24k spindle and 1900 ipm feed rate capability. Unfortunately, I wont be able to get any video because of the company rules.
@colinfoster27 Kinda looks like one huh. That would be an expensive handle out of 17-4. We tested on MP35N last week, did great. This stuff is nasty. 35% nickel, 35% cobalt and 20% chromium. Will be uploading the video soon.
I've run that machine before and I don't recall it moving that fast...but the video doesn't appear to be altered. Perhaps it's newer than the one I ran.
@caulk04 Also, do the chips stay silver or do they turn colors after hitting the chip pan? I often make chips that come off so fast they are silver, but turn blue/purple once they land.
congratulations, you program it fast, but have poor choice of rapid locations, cutter engagement locations, and how long exactly did the cutter last in the materials you machined?
Don't let the "Haters" get you down! Most end mills would survive not survive at those speeds and feeds in that material! If they did, the part would be glowing red!
@johnstonebreaker Thank you. This video was not to showcase my programming skills (or lack of :-) ). Hopefully I can get surfcam to program the next video I want to post. I am looking for 1500sfm with .05 radial, .01 ipt and 1.00 deep on 4340 at 30rc.
you need parallel keepers, and your core roughing toolpath Z-retracts are super inefficient. You probably spend 50% of your roughing pass cutting air. You must use mastercam x3, I have the same problem with my toolpaths. The new X5 with microlifts solves this issue.
Heat is still generated, that's simply a matter of physics. Work requires energy, energy has to go somewhere. In this case, it should come out with the chip. It's either in the chip, the tool or the workpiece so where is it going?
Chances are, the chips aren't even hot enough to turn that gold-blue color we'd like to see in a dry milling scenario, so yeah, there's a lot more 'work' capability here but then, these are extremely light radial cuts. What tool engagement angle are you running?
As I stated, almost no heat is generated. The cutter temperature at the end of the cycle was 125 degrees. part temp only rose about 5 degrees. The light radial cuts were to utilize the machines full potential. As programmed, this endmill can remove 20 cubic inches of material per minute on a low power machine. Cutter life is also greatly extended over a more conventional milling process. This grind will also handle slotting quite well and at a higher rate than many new cutters.
@jamesu229 You can state whatever you like, but zakne is absolutely right. Heat is absolutely generated. You cannot machine metal without generating heat. If the piece and the tool are not even warm and the chips are not discolored then there is simply not enough heat to do so.
@johnstonebreaker I'm somewhat doubtful that this machine tool is actually reaching 800 ipm at any point in this video. By the look of the spindle is a Fadal. Not a Makino mag.

@gabievagyerekek 1 endmill. Speeds and feeds have to provide hour minimum engagement, excluding all non cutting moves.

Would have been nice to select "keep tool down" with a dynamic coremill to eliminate all of the retracting! Still cool stuff though...

@caulk04 these remained silver. With a deeper radial cut, the color would have changed

@Deusrexmachina If any were to hammer on a vise handle even with their hand, I'd fire him. It's not necessary and it is hard on the vise.

@ardvarkkkkk1 Or use a tube and apply low force. :) That's what I do even to tighten bolts without necessarily using so much strength.

Really funny to see the servo motors handle the base like it was made of paper when its weigh most likely would be very high.

Out standing job on the cutter, at those rates the cutters at my old work would have been broke after the second cut. Nice job and keep it up. :)
