Speed ,Feed & Depth of cut for Titanium

[australia]

Hi we would be starting a research & development project for medical stuff and it will made from Titanium, i hope you can share to me some speed & feed & depth of cut chart for cnc milling operations

Call your supplier!

Modern Machine published a magazine I'd say within the last 8 months on how machine Ti, but it was related to aircraft thin ribed aircrat parts. Check out their website.

thanks for the info

We don't do production so these speeds and feeds may be slow.
150 sfm and .0002-.002 ipm for carbide endmills (from 1/16 to 1/2")
35 sfm for cobalt drills
Keep in mind that medical parts are weird shapes and on secondary ops you rarely have much to hold on to.
I was actually hoping to see some speeds and feeds from a production guy but these work.

Simple rule:

*** This is for prototyping, not mass production***

Treat it like 304 Stainless Steel, DO NOT cut dry, avoid slow feedrates.

Tapping holes isn't fun.

There was a post on CNC Zone about tapping holes and a suggestion for using a specific brand of tap that worked well for Ti.

Try a search for Ti tapping.

Oh...I didn't see the post above, that's sounds good.

thanks again, yes your right they are weird shape, seen some drawings last friday and the problem would be how to hold on the second operation, and there would be a 2mm tap holes on it. for the mean time we would be doing prototype but i guess if finalized with the design they might go on to production unless they sent it in china, and for now i will treat machining it as stainless, been reading some articles from Boeing team on how they machine Ti.

Hi, Machining Titanium is a bit tricky job. If possible, go for wire-edm. Or follow good-ole tips. Sharp tools, not too light cuts & rigid clamping.
