Followed a 0.0008 chipload for 0.0625 roughing, then 0.002 chipload for ball finishing

Crazy! This is exciting. People keep asking me if I cut steel on my CNC and if can cut titanium then I don’t know why I can’t try steel.

You can cut pretty much any material you can find a suitable endmill for, and which one can work up suitable feeds and speeds for — potential problems:

  • need for coolant
  • low tooling engagement resulting in premature endmill wear
  • difficult to balance feeds and speeds which can result in broken tooling, or rubbing

Why did you choose a 1"16" 4-flute endmill? Extra rigidity with the extra flutes while being able to maintain decent surface speeds?

what face mill would that be? :slight_smile:

Pretty sure it’s this one

I had a set of 5 for $5 ones and it seemed like the most challenging thing to do. Speeds and feeds have to be on point

Looks pretty crisp, is this with your 60deg kyocera bit?

Yup, probably could use a little more rpm due to the tip size.

I put a little heat into it today, love how soft it feels on the machined side, nail doesn’t catch anything. Great pocket piece and thinking of making EDC items

Haha, naw. Actually him and I have talked about shapeoko setup, really nice guy.

At the end of the day the only person you should be competing against is the person you were yesterday.

That’s why we’re gonna try deep V carving with carbide create next. Love hearing the machine run while I work on other projects, it’s the best employee :smile:

Can carbide create V cut titanium - survey says yes! But default settings need to be changed.

Lookin’ good buddy!!!

My elbows still ache at the thought of drilling that stuff by hand, thank goodness we have inexpensive little robots to do that for us these days. How big is that piece and how long did it run?

Whoa! Beautiful! What endmill did you try this with?

Part is 45x70x8mm and it ran for about 2.5 hours. Pretty conservative and I didn’t stand around to watch it.

Endmill used is the same 2 flute 60 degree kyocera, also still looks brand new.

Gonna setup the other side for another go at a double bowl. The local titanium supplier will like this lol, he didn’t think I was going to be able to machine it.

Another Win for the s3. What’s next? Tool steel? Maybe i’ll pick up some 304
