As the average chip thickness increases, speed should be decreased. Material groups P, K and H show recommended starting speeds for dry machining. For wet machining, reduce speed by 20%. Recommended starting speeds are pointing to 90° shoulder milling. Starting speeds for face and copy milling can be increased by 20%. 13
