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.
The milling machine's knee rides up or down the column on a rigid track. A heavy, vertical positioning screw beneath past the milling cutter. The milling machine is excellent for forming flat surfaces, cutting dovetails and keyways, forming and fluting milling cutters and reamers, cutting gears, and so forth.

Aug 28, 2019· Milling is the machining process that removes material from a workpiece by combining the rotation of a multiple cutter tool and the advancing (or feeding) of the workpiece in a direction at an angle with the axis of the tool [].This process presents two distinct ways to cut materials namely, conventional (or up) milling and climb (or down) milling.
Answer (1 of 2): Few differences are: 1. In up milling, Cutter moves against the workpiece while in down milling, cutter moves in direction of workpiece. 2. In up milling the chip size is comparetively larger in size at first and goes on reducing at the end but in down milling, the chip size is ...
