End mill Wikipedia

An end mill is a type of milling cutter, a cutting tool used in industrial milling applications. It is distinguished from the drill bit in its application, geometry, and manufacture. While a drill bit can only cut in the axial direction, most milling bits can cut in the radial direction. Not all mills can cut axially; those designed to cut axially are known as end mills.

How to Calculate Cutting Force Sciencing

Blade Cutting Force Calculation. The shearing process that produces metals that manufacturing plants use involve a sheet metal cutting force that ensures metals are cut properly. The process is called blanking, in which a machine known as a die exerts a cutting force, which engineers call a "punch," on the plate material to be manufactured. The word "die" can also be used to refer to the part

Down milling vs. up milling liming Coromant

In down milling (climb milling), the cutting tool is fed with the direction of rotation. Down milling is always the preferred method wherever the machine tool, fixture and workpiece will allow. In peripheral down milling, the chip thickness will decrease from the start of cut, gradually reaching zero at the end of cut. This prevents the edge from rubbing and burnishing against the surface
