Sandvik Coromant – How to reduce vibration in metal cutting 50
Depth of cut
1. Do not exceed half the cutting edge length when rough boring as this will
result in too high cutting forces on the cutting edge. When finish boring
the maximum cutting depth is small. Typically less than 0.5 mm.
Tolerance of hole diameter
1. For finishing with one insert, a tolerance of IT7 can be achieved under
good conditions.
2. Tolerances will be influenced by the clamping of the tool holder, the
fixture of the component, wear of the inserts etc.
3. It is recommended that a measuring cut is made to see what adjustment
is needed to compensate for tool deflection.
4. To achieve a good surface finish and close tolerances it is important to
use cutting fluid. Cutting fluid will prevent recutting of chips and pre-
vent heat expansion of the tool and workpiece.
