The spindle can be fed up and down with a quill feed lever on the head. • The bed can also by fed in the x, y, and z axes manually. Once an axis is located at a desired position and will no longer be fed, it should be locked into position with the gibb locks. • Most milling machines are equipped with power feed for one or more axes.

But in up milling, as the cutting proceeds, the chip thickness increases gradually whereas, in the down, milling chip thickness decreases slowly. In other words, chip thickness in up milling is zero at the start and maximum at the end of a cut, whereas in down milling chip thickness is maximum at the beginning and zero at the end of the cut.

Up Milling: Down Milling: 1. This machine is also called as conventional milling. This is called a climb down milling. 2. The cutting forces act upward. The cutting forces act downward. 3. Mostly used for rough cutting operations. This is used for finishing operations. 4. Due to the more tool wear rate, the durability of the tool is less.

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.
