The spindle speed must be set so that the tool will be operating at the correct cutting speed To set the proper spindle speed we need to calculate the proper revolution per minute or RPM setting We stated earlier that cutting speed or surface speed would change with Aug 14 2021 nbsp 0183 32 If you require a controlled cutout on drywall use these Rotozip 1 8 in Drywall Guide Point Cutting Bits They are made tough for reliability 8 bits are included This formula is used to calculate the net power from the depth of cut the feed per revolution the cutting speed the specific cutting force and the machine efficiency Example Depth of cut mild steel ap 5 mm Feed per revolution f 0 1 mm rev Cutting speed vc 140 m min Machine efficiency η 80 0 8 Given To calculate the proper spindle speed divide the desired cutting speed by the circumference of the work Experiment with feed rates to achieve the desired finish In considering the depth of cut it s important to remember that for each thousandth depth of cut the working diameter is reduced by two thousandths Example 2B Calculate the speed and feed for a 1 2″ diameter 3 flute carbide endmill if peripheral and plunge cutting in aluminum using a CNC milling machine in lab First lookup the recommended surface speed in Table 1 V ≈ 625 ft min and calculate the spindle speed from Equation 2 N peripheral rpm 12 215 V π 215 D
