Cutting data recommendations Uddeholm Global

For side milling the same cutting speed as for slot milling can Axial depth of cut a p = x D be used but the feeds must be adjusted in order to obtain a suitable average chip thickness Correction factor for side milling Divide the cutter diameter with the radial depth of cut See in the chart below which correction factor C f this corresponds to and multiply the chosen feed

Critical speed Wikipedia

Critical speed depends upon the magnitude and location of the shaft unbalance the length of the shaft its diameter and the kind of bearing support Many practical applications suggest as good practice that the maximum operating speed should not exceed 75% of the critical speed however there are cases that require speeds above the critical speed to work correctly In such cases it is
