Formula to determine feed rate FR = the calculated feed rate in inches per minute or mm per minute. RPM = is the calculated speed for the cutter. T = Number of teeth on the cutter. CL = The chip load or feed per tooth. This is the size of chip that each tooth of the cutter takes. Click to see full answer. Hereof, how do you calculate cutting speed and feed?Divide by 1000 to change to m from mm. vc (m/min) : Cutting Speed. Dm (mm) : Workpiece Diameter. π (3.14) : Pi. f (mm/rev) : Feed per Revolution. I (mm/min) : Cutting Length per Min. n (min-1) : Main Axis Spindle Speed. h (µm):Finished Surface Roughness. f (mm/rev):Feed per Revolution. RE (mm):Insert Corner Radius. Also, what is the formula for calculating feed rate? Milling Speed and Feed Calculator Feed per tooth (IPT) × Number of teeth Cutting speed (SFM) × 12 ÷ Tool diameter (in) × π Cutting feed (IPR) × Spindle speed (RPM) Then, how do you determine cutting speed? To determine this (you might need to break out the calculator), simply multiply the recommended cutting speed by the value 3.82 (round up to 4), and then divide by the tool diameter.What is the formula for spindle speed? When maximum speed of the machine spindle less than value of recommended milling conditions Maximum Speed of the Spindle Speed Spindle Speed of Recommended Milling Conditions n min-1 ÷ n1 min-1
