First let me say There is a lot of valuable information here on the forum and I appreciate the advice and help.
I did some searching today for different feeds and speeds people use on the various materials.
Most of the time 3 components are given. Feed rate, RPM's, and the bit size. (1/8, 1/4, 3/8,1/2 Etc)
There were many times I would get the end and say "at what depth?"
Is depth of cut per pass a standard thing that I am not aware of? Like assume one material thickness or 1.5 times bit diameter per pass. If someone says 2.5 IPS at 18,000 RPM's with a 1/4 inch bit don't you find yourself wondering at what depth? Is not the depth per pass an important component in this calculation too?
Thanks.
Jim
