· To remove excessive chip accumulation use an air blast. in the above table.
· When chips stick to the cutting edges (aluminum machining), · Cutting conditions are limited by machine power and material
use a water soluble cutting fluid. rigidity. When the cutting width or depth is large, set Vc and
· When interrupted cutting or cutting in a cast condition, the fz below the recommended values and check the machine
cutting feed (fz) should be reduced to below the values shown vibration and spindle load.
