Where to start dynamic feeds/speeds

[CNCAppsJames]

I realise early days but what's tool life like? Should be a whole lot better too?

I did a test in Ti about 4-5 years ago. Traditional toolpaths vs. Dynamic style toolpaths. 

With the dynamic paths we were getting between 150-155min of tool life. 

Traditional paths were giving us less than 70min.

Full DOC'S, 6.5% stepovers. I cannot recall the exact SFM but IIRC it was around 255, and Chipload off the top of my head... not having success pulling that one out.of the memory bank. LOL 

The MMR was nearly double the traditional toolpaths. The tools were not showing any real signs of wear until the 130min mark, and then it started going quick. 

This test was with the Kennametal 6fl tools. I believenit was the predecessor to the KOR6. 

We tried Imco, Iscar, Destiny, OSG, Sumitomo, Sandvik, SGS, Dataflute, and Ingersoll and the Kennametal beat them all handily in performance and Tool life.

Latest update on this. So far so good. We have over 160 pcs on the first endmill and still going strong. Tool life on the other tools is better than we had in the other machine, so this is also a win there.

Working on speeding up the other operations (finishing) today. Hoping to get 5 mins 35 seconds a rod out so that adding our roughing operation is free. This will reduce handling and machines needed in that cell, as well as man power required.

This is a fun project for me and I enjoy this challenge. The tool rep from Garr will be here today to look at things and give me his opinion. I will test other brands as well and see if I can get something with more tool life if needed.

If you want to speed up finishing, look into 7 flute end mills.

also look into quality tool holders like heavy duty hydralic holders
or heavy duty shrink fits.
It doesn't do a lot of good spending big $$$ on fancy high tech endmills
if the tool crib puts them in a Weldon holder and tightens the screws up with a 5 foot cheater bar.
Then your fancy 7 flute endmill is running out so bad it's really a 4 1/2 flute endmill

I swapped out a 4 flute Fullerton for a 7 flute Garr and was able to increase feed rate and keep the same surface finish we are after. I have been using mill chucks from Techniks for my holders. We don't have shrink fit here, that's been discussed, but it's a big expense that may not be needed right now.
