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.

May 05, 2017 Climb Milling vs. Conventional Milling. There are two distinct ways to cut materials when milling: Conventional Milling (Up) and Climb Milling (Down). The difference between these two techniques is the relationship of the rotation of the cutter to the direction of feed. In Conventional Milling, the cutter rotates against the direction of the feed.

Jan 01, 2003 For low immersion up-milling, the Hopf lobes are located to the left of the flip lobes, while for down-milling, the Hopf lobes are positioned to the right of the flip lobes. Also, the frequency plots of up- and down-milling cases show this special duality or mirror symmetry for immersions 1/2 and below.

Climb Milling = Down Milling. Conventional Milling = Up Miling. Climb milling is when the direction of cut and rotation of the cutter combine to try to “suck” the mill up over (hence it’s called “climb” milling) or away from the work. It produces the best surface finish.

Up milling:-In up milling, cutter rotates against the direction of table feed. Chip load on teeth (or uncut chip thickness) increases gradually from zero at the point of engagement to maximum at the point of disengagement. Here, tooth experience gradual loading as contact starts with a line.

Up and Down Cut (CLIMB) Milling. When choosing a method to machine, up cutting or down cut milling (climb milling) is decided by the conditions of the machine tool, the milling cutter and the application. However, it is said that in terms of tool life, down cut (climb) milling is more advantageous.
