I'm new to milling and just getting started with my manual mill. I have acquired lots of tooling new and some used. End mills of all shapes and sizes, shell mills, face mills, fly cutters ect ect.
My question is what tool to use for a specific job? Is there a chart or cheat sheet? It seems like some tools will do the same type of job as 4 other tools. But I just don't know where to start.
Ben a good rule of thumb is run your end mills
And shell mills slow enough that you can see the flutes . Or fast enough that they can't be identified .
Then back off some until you start to see them .
A six flute will run slower that a four flute
A two flute will be faster than the four flute .
This speeds will keep the RPMs low enough.
That way you don't burn up your end mills.
I am talking about Steel & Cast iron
Aluminum is soft and more forgiving.
Tool steel run your cutters even slower
Keep cutting oil on them .
Stainless Steel Slow
