High Speed Milling alum

I've been working with composites, so it's been a while since I've done high speed machining. What kind of sfm do you all use? We're running a VF3 and a VF6. They use IMCO M203N High Performance Streaker End Mills.

 

Thanks

 

 

With a haas id say try starting w/ 1000 sfm.

If it handles it bump it some more.

 

 

 

 

 

 

 

 

 

PEACE :D

Does the machine have the high speed look ahead on it?

Are you doing 2d or 3d or both?

 

What is the max spindle on the machines?

This all makes a diffrence to give you the info needed.

 

Are the EM 2 flt or 3flt or 4flt?

 

 

What he said. There are too many variables to guess what sfm you need to run. You could have three machines with 10,000 rpm spindles and have to run them differently depending on the machine.

On a Haas. I have a VM-3, with a 12000 rpm spindle. I run 1500 SFM on the roughing. EX: 12000 rpm, 100 ipm. I use a rougher at the start as it breaks up the chips so the coolant system can flush the chips out. For the jobs I do, .500 depth of cut works well as I usually have a lot of posts to cut around.

WIth aluminum... MAX RPM and probably .030-.040 chipload if using High Speed Style Toolpaths and 5-10% stepover and FULL DOC.

 

The Haas should be able to handle that.
