FEEDS AND SPEEDS

[CORBIN92087]

I JUST USED OUR 1" INDEXIBLE END MILL TO MILL OUT A 3/16" DEEP POCKET. THE MATERIAL IS A36 A.K.A. 1018. THE LINEAR FEEDRATE I USED WAS 40IPM. AND THE RPM WAS 1000. SOMEHTING IM DOING MUST BE WORNG BECAUSE ITS WAY TOO LOUD. WHAT SHOULD I CHANGE OR DO DIFFERENTLY???

There are soo many variables involved like, type of machine, grade of carbide, chip break style the list goes on and on........I will admit that the first thing I do when cutting something new to me, or a new tool to me is hit the books, or call the tech dept for the specific tool manufacturer. I will say though, that even uncoated carbide should be able to handle 500sfm safely and 1000 rpm and 40ipm sounds like a pretty heavy chipload. Once again how many inserts? Lots of variables. The other thing is that even though it may sound like **** does not neccessarily mean that your speeds and feeds are wrong. Some tools need to be beaten on to last. Just like running some grades of carbide dry, a little disconcerting at first seeing sparks and glowing chips but they like it!

I do not need any more info. The chipload is too heavy even for the most rugged machine. It should have been more like 8 ipm. Try 1500 rpm and 8ipm. I do not know how many flutes but a 1.0 dia indexable should have at least three. I think it will work in this range.
