Variations
As mentioned before,
milling is a very versatile process. It includes many machining
operations such as: slotting, drilling,
reaming,
facing, and pocket removal.
Slotting
Slotters are vertical
shapers that are used for machining notches, keyways, and dies.
They are capable of producing complex shapes, such as cutting a
helical impeller, in which the workpiece is rotated during the cut
through a master cam. Due to low production rate, slotters are generally
used in toolrooms, job shops,
and repair work.
