Cutting Speeds & RPM Calculations ChartsFormatApplicationsExampleAppearanceResultsTechnologyEquipmentUseThe three factors, cutting speed, feedrate and depth of cut, are known as cutting conditions. Cutting conditions are determined by the machinability rating of the material. Machinability is the comparing of materials on their ability to be machined. From machinability ratings we can derive recommended cutting speeds. Recommended cutting speeds are given in charts. These charts can be found in the Machinerys Handbook, textbook, or a chart given to you by your tool salesperson. In Table 3 you will find a typical recommended cutting speed chart for drilling.
