The main and basic difference between up milling and down milling is the direction of rotation of cutter to the feed. The milling operation is used to facing of those work piece, which are not symmetrical from its axis. It is also used to cut pockets, drill, slot and shape the work piece according to the requirement.

5) Power consumption. Power consumed in feed motion: up milling is higher than forward milling. Under the same cutting condition, the power consumption of down milling is 5% – 15% lower. 6)Chip removal: down milling is more suitable for chip management. Down milling is a general choice to improve surface finish and ensure the accuracy.

Advantage . The rotor blades can be flexible since there is no danger of a tower strike. The flexing blade has two advantages. 1. They can be less expensive to make. 2. They can relieve stress on the tower during high or gusty wind conditions since the. flexing allows some wind load to be transferred directly to the blades instead of the tower.

The Up-Cut Bit. One of the biggest advantages of the up-cut bit, is the ability to rapidly evacuate chips out of the area that the bit is cutting. This is very important, especially when cutting hard materials, like aluminum, deeper than 1/8″ where you run the risk of recutting chips, which can ruin the finish, cause chatter, or break the bit.
