Love the charisma!

Holy cow! That endmill simulation video of the chip forming was incredible to see! I'd love to see more video on that and deep cuts where you'd end up with multiple flutes in the cut at the same time.

How to calculate what pitch we need to interpolate at. I am interpolating a 125mm dia, 8 tipped high feed paramet cutter into the casting with 145mm hole to bore it to 152mm. The feeds and speeds are calculated but really confused about increment of Z into the bore. I tried same cutter same feeds and speeds for a bigger bore in the same casting which is about 180mm and used an increment(pitch) of 0.5mm per lap but the same increment is not working for 152mm bore. Could you please explain how to calculate that?

What a compliment! Exactly what I was going for. Thanks for watching! Ctc

I want to know how many things can make a peak finish like a helix (45' ?) , Rake angle 10 , 20 ' ? , Cusp Height, step over, Wiper ( I heard that Nissin ball nose design like insert wiper, etc... why mention only cutting way, not mention the other factor.

The problem I've run in to, in a formula 1 team, is the axial forces make the parts vibrate quite aggressively. This means the delicate parts we machine will rattle too much and damage the tool.

In high speed (Volumill) machining, the tool does not slow down in the corner. The toolpath engine makes sure that all corners are 10% greater radius than the tool radius allowing the tool to maintain its velocity. The cutoff point between HSM and HFM is the depth and width of the feature. (Generally 3X Depth of the cutter diameter and 4XW)

23:47 in my hole?

Thanks

Another Great Video!

awesome, hopefully not too long for the next video😁

great info, I'm biased because when I came up I had a lot of problems with feeds and speeds engraving titanium rings, back in the day Harvey site had all my feeds and speeds handy, I'm in a job shop now and I always recommend Harvey to the boss, near retirement and just want to say thanks for the service

KEEP ON MAKING THEM.

Great explanation, I've seen tools like this but didn't really understand what I was seeing

First ever My experience with circle segment cutters is that they aren't as great as they seem. The sell is that they are versatile, and I thought I would have them as dedicated tools in my machine but that just isn't the case. First, they're expensive. Second, holders are a problem. Helical solutions is just now making standard inch sizes so this might not be as problematic now for us American machinists. Third, full five axis machining is slower than three axis on most machines. Typically less rigid as well. Plus the holder being longer, and less beefy... You lose all the speed you gained from bigger step overs. Third, programming is a pain, especially for pockets. At least in mastercam. It does really weird things in the corners forcing you to attack it one side at a time. Furthermore, you need to be careful with excessive c-axis motion. This is not shown in backplot or verify, and is difficult to notice in simulation unless you're specifically looking for it. For pockets, I found 3+2 rough-finish followed by a ball nose clearance cutter from Harvey to get the fillets in multi axis to be the most effective, fastest, easiest and most reliable approach. The sales people are going to tell you to use a taper form for the sides, an oval form for the corners, and a lens form for the floor using 30 different tool paths. Plus painstakingly verifying the tool paths in simulation. Maybe the next video will change my mind though

So can we use ball nose end mill to surface a flat piece of aluminum 10 mm thin ?

Another awesome video. You tha man Don!

Another great video!

Don.. New video please...

So which of the two H40ALV-3 Uncoated/Zplus has a better performance-price ratio for the 6xxx and 7xxx series aluminum? Great channel👌

Thanks for an excellent explanation of the "Your four flute ball end mill is really a two-flute at shallow DOCs"! Very informative and clear. Just one hopefully constructive comment, (please feel free to ignore my advice). The "meat" of the video doesn't start until 3 minutes 52, I very nearly clicked away about five times during that hugely long intro. Asking me to like and subscribe before delivering anything of value is also a major turn-off, and the extended repeat of what was covered in the long outro also had me very close to clicking away. If you chopped the intro and most of the outro, and did the call to action right after the big reveal about 5-axis milling, like "If you've found this useful, please like and subscribe if you think I've earned it", I would have watched the entire thing and clicked all the right buttons immediately. Absolutely excellent descriptive content, definitely 10/10 for the "meat in the sandwich".

Small diameter, reduced shank, carbide High feed mills are good for making deep skinny enclosed slots

Great video

Keep the series going! Liked it very much

I have almost 2 years programming some 3d surfacing and never understood why my finishes never were as good as I wanted, I knew something was wrong with my feeds and speeds. Thanks a lot for the great knowledge shared here!!!!!!! This what I was looking for!!!!!!

excellent video!

TWO MINUTES of useless banter before getting to the tools is TOO LONG. Cut the BS and get down to business! Check the stats and I'll bet you lose a lot of readers because of this.

I use my 5 flute helical chip breakers to finish all the time. They leave a great finish on stainless. Absolutely love these endmills. My favorite to use by far. Cut great and amazing tool life.

thanks

Nice thanks

Thanks

I don’t understand about chip splitters offset between next flute. If splitters should be placed in 1 line to avoid double chip load, but in this case we get poor surface.

dude knows what he is talking about (refreshing...)

The music is too much.

Don... Aluminum is a soft material.. Which is that gummy material? Is sterl is gummy? But steel is hard material and we do machining that with tool of more number of flutes. right?

excellent video - using this in class

Could you teach me about the rake angle for cutting HARD MOULD, SKD61 55 hrc up? I use helix 30' rake -2 -7 +10. Why is +10 the best one.Theory said minus good for hard metal
