SPEEDS AND FEEDS FOR EXOTIC MATERIALS 1

[ashyarugby]

HI THIS IS MY FIRST POST HOPE I AM IN THE RIGHT ONE
I AM A CNC TURNER/MILLER NOW DOING CAD/CAM I HAVE NEVER BEEN GOOD AT WORKING OUT SPEEDS AND FEEDS BUT I COULD NORMALLY TELL IF JOB WAS CUTTING RIGHT NOW I AM SAT IN OFFICE CANT HEAR THE JOB SO I NEED TO BE WORKING SPEEDS AND FEEDS FOR INCONEL AND TITANIUM ARE THERE ANY WEB SITES OR BOOKS WITH CORRECT SPEEDS AND FEEDS
CHEERS

Here is another well known source. Perhaps you could get a copy from a local engineering college or a bookstore to look it over:

http://www.amazon.com/Machining-Data-Handbook-Machinability/dp/B000F3NHKW

Good luck with your search.

Most tooling manufacturers will have sppeds and feeds they recommend. In my experience these materials will have to run between 100 and 150 sfm depending on machine stability and exactly what the material is.

Contact President Titanium and ask if they would send you one of their product catalogs. It has decent general guidelines for grinding, turning, and milling titanium. PH 781-294-0000.

could any one inform me where to find these book s for free

No, we paid for our copies.

engroshdy24,
The type of information you are asking for is all over the internet and of course it is free. All you have to do is put out the research effort.
See below for some examples.

http://www.google.com/search?hl=en&q=speeds+and+feeds

Of course it really isn't the same as owning your own "Machineries Handbook" or equivalent.

It is really nice to have your own library of current information.

 

[tomwalz]

Yes, there is a huge amount of information that is still only available in bound volumes. Machinery’s Handbook, CRC Handbook of Chemistry and Physics, Glover’s Pocket Ref are at the top of my list.

As a somewhat author I can tell you that a huge amount of work goes into technical books for only a little return. AWS, ASM, and similar are doing a service by publishing these. They really are a bargain. Besides they look really good on your bookshelf.

Most Titanium works best at 150 with carbide tools. Maybe half that for highspeed. Inconel down to say 50 in some instances carbide tools. Chip load depends on size of tool size of cut etc.

Best bet is the following:

Machining Data Handbook Machinability Data (Hardcover)

It has everything and is a great place to start. Hope you can find it - try Ebay? or SME

Another thing to keep in mind is that there are so many variables involved in machining a part that it really isn't worth your time to try and find the ideal speed/feed, because the Setup Machinist is most likely going to change it (or try to change it) anyway. Even if you hit the bullseye PERFECTLY, the Machinist will still try to tweak the program to improve surface finish or cut cycle-time. If he didn't try, he wouldn't be doing his job. He has sound feedback, visual feedback, the vibration of the machine... all these things to help him that you don't have in the programming department. So be somewhat conservative at first and when the job is in production mode, go out and take a look at what they've tweaked the settings to, then you have a better idea of where to start next time.
