machining parameters for MDF

[andy55]

I'm going to be cutting MDF with a 2-flute 6mm cutter running at around 30krpm.

What would be ideal machining parameters (feed, depth of cut, stepover)

I will be doing a rough mill first and then a finish pass.

My router can go up to around 10000 mm/min or 393 ipm

thanks,

Andy

Try 6mm depth at 3000 mm/min for starters, but you'll probably want to feed faster at 30K rpm.

I don't know how heavy your mill is but where I work we build molds out of mdf and we rough .5 deep 350ipm 4500 to 5000rpm. We use 1 inch ball with carbide inserts.
