    Understanding CNC Cutting Tool Speeds Feeds

    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).

    Unit 2: Speed and Feed Manufacturing Processes 45

    Speed, Feed, and Depth of Cut. 1. Cutting speed is defined as the speed (usually in feet per minute) of a tool when it is cutting the work. 2. Feed rate is defined as tool’s distance travelled during one spindle revolution. 3. Feed rate and cutting speed determine the rate of material removal, power requirements, and surface finish. 4.

    Pitfall #8 – No Adjustment for High Speed Machining. High Speed Machining (HSM) is nothing short of magic when it comes to speeding up jobs and even, in many cases, improving tool life at the same time. But, there is no simple cutting speed formula available to give proper feeds and speeds for HSM.
