2. Milling
Position and diameter
In general face milling, the cutter diameter should be 20-50% larger
than the cutting width and the cutter should be positioned slightly
off-centre. Do not position the cutter exactly in the centre.
When the cutter diameter is smaller than the workpiece, it is
recommended that maximum width of cut is 60-70% of the cutter
diameter.
In full slot milling, it is very important to reduce the number of
engaged inserts to avoid vibration.
