Note:<br />
· To remove excessive chip accumulation use an air blast.<br />
· When cutting interrupted surfaces like a casting skin, the cutting feed<br />
(fz) should be set below the values shown in the above table.<br />
· Tool overhang should be minimized.<br />
When machining with long overhang applications the tool tends to<br />

· Cutting conditions are limited by machine power and material rigidity.<br />
When the cutting width or depth is large, set Vc and fz below the<br />
recommended values and check the machine vibration and spindle<br />
load.<br />
