Determine the spindle speed (RPM) and feed rate (IPM) for a drilling operation, as well as the cut time for a given cut length. Drilling operations are those in which a cutting tool with sharp teeth, such as a twist drill, rotates and feeds into the workpiece axially, forming a hole with a diameter equal to that of the tool.

Effect of Mill Speed on the Energy Input In this experiment the overall motion of the assembly of 62 balls of two different sizes was studied. The mill was rotated at 50, 62, 75 and 90% of the critical speed. Six lifter bars of rectangular cross-section were used at equal spacing. The overall motion of the balls at the end of five revolutions is shown in Figure 4. As can be seen from the ...

Cutting Speeds & RPM Calculations

Apr 15, 2014· *At 300 rpm move the drill's diameter, decimal point one place to the right. .250 drill 1/4" 300 rpm, inches per min. feed rate = 2.5 IPM.* *3000 rpm move 2 places to the right. One half inch drill 1/2" drill = 50 inches per minute.* If the material will allow you to go 9000 rpm (3 times 3000), then 150 IPM. This keeps the chip load the same.
