now put it in my DMG reduce the cycle time by half

you need to look again. I am using SinterGrip jaws. They are only gripping on 0.09" of material. The material has no support underneath it.

+Brian Stall It's not just what your holding in the vise. Its all that material above the vise to surface cut with the end mill absorbing also. The part looks good no doubt. How many could you do like that? Could you do 50 to 100pcs without changing tooling or inserts?

We cut the demo down until there is no material left. Yes the tool last for a long time months, I don't count parts, since parts have different shapes and amounts of material removed. And we have several different demos tan with same tool. Since September 2015, we have changed the tool one time. That's what you get when you run on top quality machine and spindle.

This is a machine/tooling demo showing various strategies and machine capabilities. Not a production part. Cheers.

@@BrianStall are you using the old espirit or the espriti TNG?

@@fredrezfield1629 I try to use TNG as much as possible. V4.9

MachinedConcepts It will work with Hi-Cut or SuperNurbs. We run the demo on any of the GENOS or MB-V/H machines with either option. I don't recall if the machine had SuperNurbs option in video. We actually demo it on our MB-4000H with Hi-Cut. Is there a particular reason you are asking? If you are looking for speed in 2D cutting, then Hi-Cut is the right option. If you are going to be consistently machining very high precision, true 3D path, surface finish < 8Ra, or 5 axis simultaneous, then I would invest in SuperNurbs. Because Okuma mills are 100% digital and has a PC based control, Hi-cut outperforms the majority of other builders dynamic motion software. Hi-Cut has 3000 block look ahead. The digital encoders and PC based control can communicate at 3 to 5 milliseconds, which is the real factor for achieving high machining speeds while maintaining accuracy.

Brian Stall Thanks for the detailed answer. I looked at this machine and both these options... but I guess this clears up the major application differences between the two options. Is Hi-Cut an option or is it standard?

MachinedConcepts Hi-Cut is standard.

Not if your machine can reach and maintain a fast enough feed rate!

For clarity, I mean the rotational speed of the surface of the tool, called Vc, the speed at which the edge is cutting into the material. Not the RPM or the feedrate :) Officially, steel has a very narrow range of Vc that it can be cut at, around 200m/min, which is about 8000IPM, but you're going over twice that speed with good results, which is interesting! This is according to a moderately old handbook I have, so it might be wrong with it comes to modern techniques :P

@@bluustreak6578 Gotta say mate, you made yourself look pretty dumb in front of all of the people here. Obviously we know that rpm=vc, have a look at radial chip thinning, and how it affects your feed.

But RPM is not Vc. Vc= RPM*ToolDiameter*pi Vc is the speed that the cutting edge on the very circumference of the tool is travelling at, and while it is indeed dependent on RPM, there's more to it than that. Steel likes to be cut at a specific speed, and that cutting speed is meassured in Vc. And yes, the feed can be increased a lot with a small Ae(radial engagement) due to chip thinning, however, this does not affect the allowed Vc value. EDIT: just for clarity: Feed speed(Vf), RPM, and surface speed(Vc)(which is what I call rotational tool speed) are three totally different things

@@bluustreak6578 Yes, everyone here knows that. Surface speed and RPM are not totally different, and radial chip thinning does allow for a higher rpm.

For what tool and operation?

Brian Stall My guess is the tool that's using inserts! ;-) My question is: what's the rDOC of that first solid carbide end mill? 12k@700IPM tells us a little since we know the diameter of the tool, but how many flutes? I don't want to try and find that tool on Sandvik's website. aDOC?

atomkinder67 It is a 4 flute end mill. The part # is at the top right corner of screen. Sandvik now has the new Plura HD line, which you can get in 5 flute with variable pitch. 7% - 10% diameter of tool for rDOC. aDOC in video is 0.75", but you can use tool's entire max ap value.

+jonathon friedl Like what?

The first and second tools seem pretty inefficient. Why the high high speed swirly on a face mill? Why the pause at the beginning and end of the cut on the second tool?

+Brian Stall But you know what, in the grand scheme of things, this is a pretty damn impressive machine. Great surface finish, lots of torque and rigid enough to handle 4140 like a haas handles aluminum.
