WebFPT is in inches per tooth (IPT) or millimeters per tooth (MMPT). Choose the proper chip load factor (CLF) based on the radial depth of cut. Now choose the right surface feet per minute (SFM) or surface meters per minute (SMM) Use the SFM and the diameter of the mill to calculate the RPM of your machine. WebCalculate the Feed per Tooth, based on the Chip load and Chip thinning factors: F z = C L × R C T F × A C T F Calculate the RPM from the Cutting Speed and Cutter Diameter: n = V c × 12 π × D * If your Vc is in m/min units use 1000 instaed of 12 in the above formula. Final Stage: Calculate the Table Feed: V f = F z × n × Z
