In up milling, the direction of the cutter rotation is opposite to that of work done.Whereas in the down milling, the direction of the cutter rotation coincides with the feed direction.. In up milling, the thickness of the chip is minimum at the beginning of the cut and it reaches to maximum when the cutting ends.Whereas in the down milling, the cutting forces …

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.

Climb Milling versus Conventional Milling [ Sneaky CNC. Mar 22, 2018 Advantages and Disadvantages of Up Milling and Down Milling (Conventional vs Climb) Advantages of Conventional Milling (Up Milling): The width of the chip starts from zero and increases as the cutter finishes slicing. The tooth meets the workpiece at the bottom of the cut.

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.

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.

In a milling operation, the workpiece is fed either along or against the direction of the cutter rotation, which affects the start and finish of the cut, as well as if down milling or up milling method is used. The golden rule in milling – thick to thin When milling, you always need to consider how the chips are being formed.

In milling process, there are two separate ways by which we can achieve cutting of materials from the workpiece. The first method is called as up milling and the second one is down milling. The fundamental difference between these two processes is the direction of rotation of cutter relative to the feed motion.

Milling machines allow you to use drill bits to cut up and down, but drilling machines don't allow you to cut horizontally with milling bits. For this reason, it's easy to present the idea that milling machines have a wider range of uses. It's also worth noting that milling machines have a secure hold for regular drill bits.
