Dymamic Milling speeds and feeds

[Mr. M]

I know for the Aluminum stuff we do I run most of the endmills at the max rpm (for me thats 10k) and on the Ti job I have the endmill doing a 6% stepover. The chip thining calculator tells you what the actual chip load is.

I cut alot of 1018 steel and I run a 1/2" 5 flute carbide endmill at 5000rpm ~ 200ipm 1.25" deep cut the full length of the endmill with .05 step over. I also run it dry with air blast and it last forever and sounds great. The blocks im cutting are 1.25" thick and 3.25" wide and 7" long and im cutting almost have of it away. One endmill last me 25-30 parts easily. I have had it last 40 parts, I just run it until it breaks. At worst im paying $45 an endmill so I figure it cost me around a little more than $1 or so a part. Pretty good considering how fast it knocks the parts out.

I did forget to mention that when I come into a corner I do go down to 50 percent on the feed otherwise it sounds real bad lol.

Fraisa's new NX-NVD tools have been out-performing Varimills in steel & titanium.

 

These also have beaten the Varimills.......
