Adjust the cutting speed and/or feed rate based on your cutting conditions. NOTE: All speed conditions are for stable conditions. For unstable conditions, it is suggested to reduce starting speeds by 10%. For interrupted cuts, reduce by 20%. For 4 X D, it is highly recommended to start with feed and speed values reduced by 10% less than above data.
