Understanding CNC Cutting Tool Speeds & Feeds

SFM is a combination of diameter and the velocity (RPM) of the material measured in feet-per-minute as the spindle of a milling machine The faster the spindle turns, and/or the smaller the diameter, the higher the SFM The goal is to tool a job to run the SFM as high as possible to increase hourly part production...

Drilling Speeds and Feeds

Drilling Speeds and Feeds The speed of a drill is measured in terms of the rate at which the outside or periphery of the tool moves in relation to the work being drilled The common unit and term for this velocity is surface feet per minute, abbreviated sfm Every tool manufacturer has a recommended table of sfm values for their tools...
