The routers according to the number of axes can be three, four and five axis.
Operations during the milling process cycle are as follows:
End milling: Tool mill makes peripheral and slot cuts across the work-piece.
Chamfer milling: Tool mill makes a cut along of the work-piece to create a 45 degree angled.
Face milling: Machine works in a flat surface of the work-piece to create a smooth finish.
Other operations are drilling, boring, counter boring, countersinking, tapping and reaming.
