When milling or drilling or creating a tool path for a CNC machine the feed rate must be determined Materials have rated surface speeds for a given type of cutter The harder the material the slower the speed Given the diameter of the tool and the surface speed the RPMs of the spindle can be calculated Then if the tooth load for the cutter is know and the number of teeth the feed rate ## Drilling Speed and Feed Calculator

This RPM and IPM calculation formula for drilling can also used to figure out how long the cutting time would be in minutes for a given cut length Our CNC machining formula collection also provides Milling Speed and Feed Calculator and Turning Speed and Feed Calculator accessible to anyone Feeds and speeds are usually all set in the programming software you always have chance to calculate ## Calculating Output Speed Using Pulley

· RPM Output/RPM Input = Multiplication Factor On a belt driven fan the two primary speeds required are the RPM of the Motor and the RPM of the fan For example if you know the motor speed is 1778 rpm and the fan speed is 944 rpm the multiplication factor would be 944/1778 = 5309 The multiplication factor is input into the Nest when building a machine If you can t get to the fan shaft to ## Milling Speed and Feed Calculator
