Cutting Speeds RPM Calculations

Cutting speed is the speed at the outside edge of the tool as it is cutting This is also known as surface speed Surface speed surface foot age and surface area are all directly related If two tools of different sizes are turning at the same r evolutions per minute (RPM) the larger tool has a gr eater surface speed Surface speed is measured in sur face feet per minute (SFPM)

Speeds and Feeds Charts

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 Use the RPM IPT CLF and the number of flutes to calculate the feed rate or IPM
