 Conventional Milling (Up Milling)
 Max chip thickness is at the end of the cut
 Advantage: tooth engagement is not a function of workpiece surface characteristics, and
contamination or scale on the surface does not affect tool life.
 Cutting process is smooth
 Tendency for the tool to chatter
 The workpiece has a tendency to be pulled upward, necessitating proper clamping.
 Climb Milling (Down Milling)
 Cutting starts at the surface of the workpiece.
 Downward compression of cutting forces hold workpiece in place
 Because of the resulting high impact forces when the teeth engage the workpiece, this
operation must have a rigid setup, and backlash must be eliminated in the table feed
mechanism
 Not suitable for machining workpiece having surface scale.
