Need a litttle more info, what tool number are you using? is this when your cutting 5/8" birch ply? what are your feed, speed and stepdown, is the scream continuous thru the whole cut or mostly at ramping speeds, are you cutting climb or conventional? are you doing an LP toolpath for the final pass?
If you would like to discuss, your welcome to call me

Eric, I see you noted the scream in the corners, what is your ramping feedrate?
