| Recommended Starting Speed are pointing to 90° Shoulder Milling . Starting Speed for Face and Copy Milling can be Increased by 20 %. As the average chip thickness increases, speed should be decreased. Material groups P, M, K and H show recommended starting speeds for dry machining. For wet machining, reduce speed by 20%. Material groups N and S show recommended starting speeds for wet machining. Not recommended for dry machining. | |||||||
