Cutting speed (SFM) SFM - Also called surface speed or simply speed is the speed difference (relative velocity) between the cutting tool and the surface of the workpiece it is operating on. It is expressed in units of distance along the workpiece surface per unit of time, typically surface feet per minute (sfm) or meters per minute(m/min).

Horizontal vs Vertical Milling Machines

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.

Using an end mill to do face milling is often inefficient, but can create some appealing patterns in your finish, if that's what you're after. An end mill often comes to a sharp point at one corner and the bottom edge is usually at a 1° angle as it goes to the center, so it doesn't overlap with the previous pass.
